Return E level and electron dot quiz from last Thursday.

Review of methane molecule Practice possible quiz questions: Matching: carbon's nucleus, hydrogen's nucleus, carbon's level 1 and 2, hydrogen's level 1, covalent bond site. Draw energy level and/or electron dot diagrams for both Hydrogen and carbon KNOW: how many protons, neutrons, and electrons are in hydrogen and carbon. Methane molecule quiz tomorrow!!

Review pages 14 and 15: Predict the charge quiz is on Thursday!! Finish page 15. = = =Friday, May 25: Kolt L, Michael G, Hannah K, Joe D, Olivia N= YOU HAVE ONE DAY TO COMPLETE THIS LAB ACTIVITY 1. Color 10 circles red 2. Color 6 circles yellow 3. Cut out the cirlcles (Red are protons, Yellow are neutrons) 4. Start to draw your methane molecule in the center of the paper using energy levels for carbon in the center of the page. Leave room for 6 red circles and 6 yellow circles in the nucleus. The nucleus should never touch an energy level! 5. Draw a single energy level for hydrogen 4 times at compass points connecting energy level 1 of H to level 2 of C Step 4 and 5 picture:

6. Glue 6 protons and 6 neutrons in the nucleus area for carbon. I need to see 12 things here! This is why carbon is 12 x heavier than H 7. Glue 1 proton in the center of each hydrogen energy level. 8. Glue the small green circles (or electrons) in the energy levels where they belong. (Carbon has 4 outer electrons and hydrogen has 1... when their outer energy levels match up, their electrons pair next to each other at the meeting point of levels) 9. Make sure you have 10 electrons in their correct place! 10. Copy the notes in the corner of a page!! Label Carbon E level 1and 2, Hydrogen's E level 1, C's nucleus, H's nucleus, one covalent bond site You will have a methane molecule quiz on Wednesday 5/31 THIS MOLECULE NEEDS TO BE COMPLETE BY NEXT CLASS. Whatever you do not finish is homework. = = =Thursday, May 25: Michael G, Hannah K, Olivia N, Devin D= Electron dot and energy level diagram quiz (25 points) (students that were out for keystone testing yesterday will take this quiz tomorrow!!)

Guided notes pages 3, 12, and 13. Page 14 -15 We covered the bottom of page 14 and the top of page 15.

Please remember that the t in caTion looks like a positive sign. Mettttttttttals form cattttttions by losing electrons. The metals are usually found in groups 1A, 2A, and 3A. The charge it will make will be positive, matching the number of bond sites (Lonely electrons). Carbon is a sharer! It doesn't form a charge!!

Please remember that ANions (an- as a prefix meaning negative) are negative. Non-metals are the opposite of metals!! Groups 5A, 6A, and 7A contain nonmetals that will GAIN electrons to have negative charges that match the number of bonding sites!!

Here are the board notes. The predict the charge quiz will be on Thursday June 1, Practice quiz will be offered Wed 5/31 = = =Wednesday, May 24: Michael G, Champ S (Kestone: Dan C, AJ B, Alex L, Kolt L), Olivia N= Review page 1 and 2, Practice quiz for energy level diagrams like page 2. Kinds of questions: How many levels are needed? How many levels are full? How many levels are not full? Will it gain or lose electrons?

Finish Page 4. Practice quiz like page 4 Board notes for today:

Study the practice quizzes for the quiz tomorrow!! There will be no pictures to guide you. The questions will ask, draw and energy level diagram for Ar.... or draw an electron dot diagram for Ar or another element = = =Tuesday, May 23: Michael G, Alex L, Kolt L, Kaitlyn K, Olivia N= Return Ch 5 Test and Packets Board notes for today:

Review page 1. Discussion of orbitals (sublevels) and why each energy level can hold maximum of 2, 8, 18, and 32 electrons.

Finished the bottom of page 1 up to and including all of page 2.

Page 1 paragraph 6: lowest, greatest, strongly

Write At the bottom of page: attraction is like magnets. The farther away the less attraction. Closer magnets pull each other!

Page 2: para 1: protons, electrons,

Para 2: ONE

Quiz on Thursday having BOTH energy level diagrams and electron dot diagrams. Know the maximum number of electrons per energy level up to level 4. Energy level diagrams show all electrons. Electron dot diagrams show only the outer electrons. The number of outer electrons match the group number on the periodic table!!! (He*exception) Elements will either gain or lose electrons to become more stable (unless they are already stable {noble gases}). You need to see if their outer electrons are closer to 8, then they will gain! If they are closer to 0, then they will LOSE! gaining electrons makes you negative, losing electrons makes you positive! = = =Monday, May 22: Zach R, Kolt L, Michael G, Alex L, LeeAnn G, Joe D, Olivia N, Lexie Y, Devin,= Return chapter 5 packet and chapter 5 Test tomorrow due to the large number of people still testing

Got new chapter 6 packet.

There will be daily activities that will be worth class points almost everyday or every other day in this chapter!! They will be used as mini-checks to make sure you are paying attention in class. There is a lot of information to cover... stay on top of it!

Today we only covered page 1: Here are the responses for the guided notes by paragraph:

para 1: nucleus, proton, newtrons, mass, tiny (1/1840), electron

para 2: Positive, negative, impossible to know the speed and location at the same time, structure

Para 3: physical, chemical

para 4: energy levels, energy

para 5: **2, 8, 18, 32***

Paragraph 5 needs to be memorized to complete energy level diagrams and electron dot diagrams!!

Paragraph 6: least, most (highest), strongly (like magnets)

electrons move in levels as a fan blade moves in a fan, you cannot see the individual fan blade when it is moving, only the shape it produces.

Period 9: took p or c quiz (20 points) Watched this YouTube video and filled out a question sheet. This will be worth 10 points in your packet grade. Make sure you complete and it and staple it TO THE BACK of your packet. https://www.youtube.com/watch?v=kL5xGQUiAxQ Filled out the answers to the question on the end of your packet that go with the movie. Here is the question sheet if you lost it for any reason: = = =Thursday, May 11: Connor, Lal K, Olivia N, GigiA, Devin D= Don't forget about the quiz tomorrow!! P or C There are 5 general types of reactions Reaction types Notes: YOU DO NOT NEED TO KNOW THIS FOR YOUR TEST NEXT FRIDAY!!! However, if you take the reaction type notes from the board I will give you 2 points in your packet!!

Decompostion: one thing forms more than one thing (evil bunny Tuesday) We watched a chem alive version of the evil bunny with an exploding watermelon... and this clip on youtube (rainbow elephant toothpaste)

Combustion: DEMO TODAY (or yesterday) need oxygen for fire!! hydrocarbons combine with oxygen to form carbon dioxide (or monoxide) and water

The best whoosh bottle compilation ever (1:43) https://www.youtube.com/watch?v=BthkreW753I You need oxygen for fire!!! Why don't you use water to put out grease fires?

In a hydrocarbon (made of only carbon and hydrogen atoms) combustion, you produce water and either carbon dioxide, or carbon monoxide as products! The hydrocarbon combustion of methane: CH 4 +O 2 --> H 2 O + CO 2 (complete combustion) products are water and carbon dioxide CH 4 +O 2 --> H 2 O + CO (INcomplete combustion) products are water and carbon monoxide

Combination: 2 or more things form one thing Na + Cl2 --> NaCl

Show sodium plus chlorine makes sodium chloride clip and synthesis of nylon In a combination reaction you have 2 or more things combining to form only one product

Single: 1 element replaces another in a compound double replacement: 2 elements change places between compound

Complete page 7: This is an example of a single replacement reaction Show sodium in water gone wrong on youtube. This is why Mrs. G no longer does this demo... because worse than this happened to her!! If time permits: youtube search: brainiacs alkali metals: These are more single replacement reactions! https://www.youtube.com/watch?v=OrqYaDO-8K8

Study page 15 for quiz FRIDAY 5/12

Here are the extra credit notes = = =Wednesday, May 10: Amarie S, Connor P, Devin D, Lexie Y, Juan B, Olivia N,= Period 6 went outside.... The room smelled funny!! We covered the correct answers for page 15. Use this to study for quiz on Friday!

Period 9 Watermelon elephant toothpaste:( 2 minutes) Review pH (5 minutes) Review page 11 signs for chemical change:

Study page 15 for quiz on Friday!! You had 10 minutes to work on page 15 yesterday...

You have 5 minutes to compare your answers with someone else and argue your choice

Done early? switch partners again!! Go over correct answers for page 15:

We watched chemical reaction clips that show indicators of chemical reactions: color change iodine clock: (2:38) [] four color change reaction: (1:43) []

formation of a solid from 2 clear liquids beautiful chemical reactions (1:23) [] Chemistry experiment 41- Golden Rain (3:51) []

SPONTANEOUS temp change: "cool" reaction- ammonium thiocyanate (0:55) []

All but solid formation (thermite) The strangest and wierdest chemical reactions in the world. (2:52) [] all signs shown Indications of Chemical Change (5:24) []

Combustion demo??

= = =Tuesday, May 9: Kolt L, Zach R, Kaitlyn K, Connor P=

Evil Bunny: DECOMPOSITION REACTION- shows the formation of oxygen and hydrogen gas from the breaking apart of Hydrogen peroxide. Hydrogen peroxide will break down over time to form hydrogen and oxygen gas. However it takes a long time, and the formation of clear colorless gases from what seems like an evaporating solution of clear colorless liquid is boring... SO LET'S KICK IT UP A NOTCH...

by adding a catalyst (something that doesn't participate in the reaction... only makes it go quickly), postassium iodine, we get a fast decomposition into hydrogen and oxygen gas... still clear and colorless... and boring...

So we add some food coloring and soap... food coloring for flare... and soap to trap the oxygen gas. Evil Bunny Review: spontaneous gas production (we trap the oxygen in soap) Here is a rainbow elephant toothpaste clip: https://video.search.yahoo.com/yhs/search?fr=yhs-mozilla-002&hsimp=yhs-002&hspart=mozilla&p=rainbow+elephant+toothpaste#id=3&vid=1f1ffa85061fce692922f0cb88171377&action=click

We also watched chem Alive labs with the evil bunny in a funny watermelon cut out!

We watched chemical reaction clips that show the first two indicators of chemical reactions (coupled with other signs):

Gas, Temp, and Color: sugar and sulfuric acid (4:53) []

Exploding pumpkins (3:42) https://www.youtube.com/watch?v=U5oBfl1QD_g

Finish page 11: (5 minutes) last two signs of chemical change: solid forms from 2 liquids [NOT FREEZING] color change... Usually with another sign of chemical change!!

Quiz Friday on P or C changes like page 15. Page 15 is your practice quiz!! (15 minutes) You have 10 minutes to take it. You have 5 minutes to compare your answers with someone else and argue your choice Done early? switch partners again!!

=Monday, May 8: Hannah K, Michael G, Brandon K, Austin W, Connor P= (5 minutes) Review of pH Scale: acids: low pH 0-7, sour, squeaky, ex: soda, OJ bases: high pH 7-14, bitter, slippery ex : soap

(10 minutes) You may work by yourself to answer the questions on the back of the sunset/sunrise observation page. LOOK AT THE TOP! pH limits of phenol red are listed!! If you choose to work with ONE partner, you may NOT work with your lab partner from last class. Now you have two different sets of observations to help guide your responses. Observations may be similar, but maybe you can catch something you missed or have more info to make a decision. If you finish early, switch partners again, and compare answers!!

The reaction that took place between sodium bicarbonate and calcium hydroxide was the first example of a chemical reaction. Dissolving is a physical change, even though sometimes it spontaneously changes temperature. (step 4 in sunset activity) Formation of a gas and solid, coupled by the spontaneous change in temperature definitely suggest a chemical change has occurred!! (step 7 in activity)

(15 minutes) On page 8 review the definitions of a chemical property. The major difference between a chemical and a physical property is that a physical property can be seen or measured without a chemical reaction. Physical properties include color, temperature, density, odor, etc. Chemical properties cannot be seen with our eyes or measured without changing the substance in question, such as flammability, toxicity, or reactability.

(PLEASE ADD "Reactivity and Toxicity" to common chemical properties in the middle of page 8)

Mini Lab Page 8: Finish page 8 . Observations for steel wool in water: small amounts of rust in less areas Observations for steel wool in salt water: More spots of concentrated rust. More rust dust in the bag! More time... all of the steel wool is brown! Analysis questions: 1. salt water causes more rust 2. metal will lose conductivity, cost time, money for replacement after a shorter amount of time!

We filled in page 11: Completed page 11 too!! The 4 signs for chemical change are the most important to think about while answering questions in this chapter... make sure you understand them!



Quick View Evil Bunny: explanation to follow Tomorrow

QUIZ ON P and C Friday!! Practice Quiz Tomorrow and Wednesday!

=Friday, May 5: Eric N, Connor P, Devin D, Lexie Y, Austin W, Brandon K= Acid and base notes Page 5:

Stuff on board today...

1. by PH meter (acids have 0 to below 7.... water a pH of 7 and is neutral... bases are above 7 to 14) 2. by indicator (acids and bases are different colors with the liquid indicator, or litmus paper) 3. by touch (acids are squeaky, bases are slippery) 4. by taste IF SAFE TO CONSUME (acids sour, base it bitter)
 * Make sure you know how to tell the difference between an acid and a base: ESSAY QUESTION**

An acid plus a base equal salt and water. THIS IS YOUR FIRST EXAMPLE OF A CHEMICAL CHANGE

Here is a demo of an indicator with acids and bases: https://www.youtube.com/watch?v=Iiu5mcAA8pU

Sunset in a bag. Page 10.... WE CROSSED OUT PAGE 10!!! Here is the new and improved sunset and sunrise in a bag!!! Do not lost this paper!! We will answer questions next class!!

Here is A YOUTUBE VIDEO for you to fill in data and observations and also answer the questions if you are not available to make up activity on a review day before the test!!! https://www.youtube.com/watch?v=3Qi8AAulYcQ

= = =Thursday, May 4: Hannah K, Kyle S, Isaac A, Lexie Y= Absent people from Wednesday, you will measure your one block, follow directions on the board pictures below... and when time permits in another class... you may continue this activity if you don't finish today.

Check out this link on density facts: (youtube search: 5 facts about density)
 * https://www.youtube.com/watch?v=zlkpZZW29b0**

1.) As you add/dissolve stuff in water, it gets more dense, how do we use this? - Dead sea: 7 times saltier than the ocean and really easy to float in because youre so less dense than that water, see this cool density video: [] Awesome sugar density crazy Russian hacker

- Without something to mix it (like seamounts or mini ocean mountains) all our nutrients would end up stuck down there! Density gradient doesn’t break itself as you can see in this video about ocean current salinity: - []

It sinks and is really cold, eventually freezes as it travels down making a cool brinecicle. Look! - [] Brinecicle or “finger of death” - Entire ocean is driven by density! - Different kinds of layers in the ocean from different parts of the world, coldest and saltiest is Antarctic, then arctic, then atlantic, then pacific usually.


 * Look at this density chart for metals. Notice it DOES NOT specify an amount. No matter the amount, the density DOES NOT change**
 * https://sites.google.com/site/chempendix/densities-of-pure-metals**

= = =Wednesday, May 3: Hannah K, Austin W, Connor P, Evan H, Brandon K, Lexie Y, Devin D, Isaac A= DENSITY IS AN INTENSIVE PROPERTY THAT NEVER CHANGES BASED ON AMOUNT
 * Bye-Bye to Mr. S!! Mrs. G will start teaching tomorrow.**

Groups of 3: I person in each group is responsible for measuring the length, width, and height of one block in the group of blocks. MEASURE IN CM. The ruler is precise to 2 decimal places! ALL MEASUREMENTS SHOULD BE 2 DECIMAL PLACES. Density is a calculation... not a measurement. There are NO TOOLS that measure density directly. Density Blocks activity page 2 (20 points) one point per block, one and a half points per column for unit and 2 decimal places and 2 points each for questions 1 and 2)

You can have some time to finish tomorrow (10 minutes maximum). You may take this home and finish the calculations for homework if you want! .

= = =Tuesday, May 2: Hannah K, Amarie S, Connor P= Review some of the class observations for each material. If we mention a good one you don't have... copy it down!

Here are the physical properties that belong to the observations we made: Physical properties being observed in the silver powder: State, color, magnetism, consistency (texture), size, amount, luster Physical properties being observed in the magnesium strips: state, color, shape, size, color, texture, malleability, luster, transparency, amount Physical properties being observed in the salt water:state, color, amount, viscosity, transparency Physical properties being observed in the boiling salt water: additionally boiling point Physical properties being observed in the iron wire: state, color, ductility, magnetism, amount, size, shape, luster Physical properties being observed in the iron shavings: state, color, magnetism, amount, shape, size Physical properties being observed in the regular water: state, color, amount, viscosity, transparency Physical properties being observed in the boiling water: additionally boiling point Physical properties being observed in the soap: state, color, texture, amount, size, shape, smell, transparency, magnetism, texture

Each material may differ in observations even though some of the same properties are being observed.

Some properties that can be measured were not observed, like density, melting point, freezing point, etc...

Notes on the bottom of page 2: Notice the differences in a rock, baking soda, and oil. They all have different states, color, transparencies, sizes, etc. Some have viscosity and other properties that are not seen in all 3 things.

Physical properties are something that can be observed or measured without changing the identity of the substance.

Start physical properties lab on page 3 and 4. Complete the observations only for each station. You must have a state, color, and 3 other describing characteristics minimally. Someone from the hallway should read your paper and be able to visualize and think of the thing you are observing without knowing the identity

If you were absent last week make sure you complete the make-up activity. Today: Covered page 3 activity. You should cut your grid into 4 quadrants (17down, 10 across) You must use each piece provided on the board one time. The top two quadrants are crystalline, so you can create a pattern with, or without spacing using your pieces of choice. The bottom two quadrants are for the remaining pieces you have not already used, one per quadrant. You DO NOT want to create patterns with these pieces. Just jumble them up!! You cannot change the piece.. but you can have an anti-pattern arrangement of the pieces. Here are the do's and don'ts of the activity: If you were not working on this activity in class, you will lose credit for it in your packet! We will have time to work on it tomorrow. If it is not finished by the end of class, it will become homework!

=Thursday, April 13: Hannah K, Champ S, Kaitlyn K, Connor P, Jadyn S, Javier U, Austin W, Devin D, Joe D= Characteristics of solids discussion... completed page 1B: Completed making a crystal lattice lab on page 2.

Instead, you will complete the make up activity: Make Up activity: = = =Wednesday, April 12: Hannah K, LeAnn G, Bri F, Ryan A, Shayna F (late with pass), Austin W= non-newtonian fluids video: the fluid shown on it's own behaves like a liquid. When they add a force to it by turning on the speaker, it does not act like a normal liquid, but instead bunches together and hardens. Upon removing the force it goes back to a normal properties.

If you change the surrounding conditions of a liquids it's properties can change. When going back to original conditions, the properties will go back as well!

Start thinking about properties of water and why this is possible.. class thoughts: water is cohesive (sticks to itself). Surface tension keeps the water together in big blobs https://www.youtube.com/watch?v=lMtXfwk7PXg

You can over fill a glass to the point where the surface tension can contain the water above the level of the glass. You can only do this so much until the force becomes to great to hold the water together and the water starts to spill over the edge.

How many drops of water can you put on a penny?

Actual quiz on rounding, sig digs, and sig digs in calculations (15 minutes). Talking during the quiz is a 3 point deduction each time!!

Period 6 only: In the Packet... We covered the next page: Title: A FEW MAJOR SI UNIT Here is what we wrote on this page:

Tomorrow, don't forget about the POST TEST. This will be 18 points. It will be exactly like the Pre-quiz given before the chapter began. This will be used to hopefully show growth from what you knew before we started to what you know now!!

Keep in mind the difference between 125s and 125.00s (125.00s is more precise and has more sig digs.). Remember the rules you used to make estimates on the measurement lab. You can report all the numbers you know for sure plus a guess digit. What is the difference between 3cents and 3m? (one is an exact and one is an inexact number) = = =Wednesday March 8: Shelby S, Devin D, Lexie Y, Aaron B= Review of upcoming assessments: 1. Practice quiz today- Use this pdf and key to study: 2. Actual quiz tomorrow (roudning, sig digs, and +,- of sig digs) 3. Friday: 18 point post test to show growth from pre-test given BEFORE the chapter started. (covers measurement, precision, exact # vs Measurement)

Took the practice quiz. This was collected by Mr. S. It will be graded and reviewed before the actual quiz tomorrow.

Rounding and sig. dig handout was stapled to chapter 2 packet! If you didn't have either one of these today, it is now your responsibility to staple and keep track of!!!

In original packet, turn to __Section 2__: SI UNITS Board Notes: = = =Tuesday March 7: Shelby S, Kyle S, Brandon K, Aaron B, Liv N, Giavanna= Review of important upcoming information. See board notes: Also included is the review of the HW that was checked for points (the right side column of the sig dig practice on page 2).

Practice quiz Wednesday Actual quiz Thursday Post Test on Friday: Keep in mind the difference between 125s and 125.00s (125.00s is more precise and has more sig digs.). Remember the rules you used to make estimates on the measurement lab. You can report all the numbers you know for sure plus a guess digit. What is the difference between 3cents and 3m? (one is an exact and one is an inexact number)

We went over the bottom of page 2 under the sig dig columns. To add or subtract you must carry out the calculation, report the calculator answer, and then round to the smallest number of decimal places in the problem. You must show the number of decimal places in your problem and your final answer!!!! In class we completed the bottom of the next page of handout with 8 addition and subtraction answers. : For full credit on the quiz: you must write the number of decimal places next to each number in the problem show the calculator answer under the calculator answer you must round to the smallest number of decimal places in the problem show the number of decimal places in your answer.

= = =Monday March 6: Shelby S, Michael G, Devin D, Joseph D= Checked homework from Friday for points. Went over homework, odds were covered in the board notes. Think about place holding zeros' to the left of the decimal. Think about why zero's aren't place holders to the right of the decimal.

Significant Digits Covered from page 2 of the new handout from Friday. From this point forward, you will be expected to record measurements from tools used in the measurement labs to the correct precision. YOU MUST KNOW WHERE THE GUESS SPOT IS GIVEN THE TOOL! If you are given a measurement in a problem, that you did not take yourself... there are rules to follow so the reader can determine the guess spot. These are called significant digit rules. When using given numbers, we need to be able to round responses to match the precision of the tools used! You cannot report an answer that is "better" or more precise than the given data you are working with.

Here are the board notes that cover the HW answers, significant digit examples, and future homework on significant digits. HW was to finish the right side column of SD practice on page 2 of the handout. YOU WILL HAVE A QUIZ THURSDAY ON ROUNDING AND SIGNIFICANT DIGITS. There will be a practice quiz on Wednesday. For the quiz you will have to round to specific place values, determine the amount of significant digits in a measurement, and add and subtract significant digits rounding the answer to the correct precision. = = =Friday, March 3: Shelby S, Austin W= Returned the measurement quiz from yesterday and went through the answers. Begin to review rounding. Rounding is a basic concept that will be needed when adding and subtracting different value using measurement tools. You cannot report an answer that is more precise than the capability of the tool used to make the measurement. Sometimes you will have to round your response to the correct guess spot. Here is the handout for today and Monday: Board notes: (what we filled in on the handout)

In class we worked on the rounding practice. You should be able to complete number 3, 4, 9, 15, 16, 19 and 20 (next page in rounding handout). For homework, complete the odds, skipping #7 and #11. You can try 7 and 11, but for a correct response, you need scientific notation.

This will be checked for completion at the beginning of next class.

= = =Thursday, March 2: Shelby S, Austin W, Josh H, Michael G= Went over the practice quiz from yesterday. Papers were graded by you!! Put a score at the top. Mrs. G and Mr. S went around to staple this to your packet so it can be counted towards packet participation grade. Make sure you have this included when you hand in your packet. If it was not complete today, you will not get credit for it in the packet!! Here are the board notes and how you would grade your quiz. The exact same grading will be used on the quiz for today. The quiz has the same format as the practice quiz!!

The remainder of class students took the actual measurement quiz.

= = =Wed, March 1: Shelby S, Brandon K, Austin W, Devin D= Started class by going over specific examples from trial 2 yesterday (1, 5, 6, 20). Here is what you should have for this activity on these packet pages:

Before the practice quiz it was explained that students need to show the range on the tool picture, write the value of the lines for the range, pick a value for a possible volume measurement by writing all the things we know for sure, plus one guess spot. THE GUESS SPOT NEEDS TO BE __UNDERLINED__ in the estimate. UNITS ARE NECESSARY FOR BOTH THE RANGE AND THE ESTIMATE!!! Practice quiz on measurement and answers with point distribution: We will go over all answers tomorrow for a review before the actual quiz is distributed. If you have questions, please make sure you ask them before the quiz tomorrow.

Absent students, please print out the practice quiz or find the copy left for you in the back of the room. Follow the directions and complete this before the packet is due!! = = =Tuesday, Feb 28: Shayna (late with pass), Austin W= Note: All students that were late or in the nurse at any time during this class are responsible to have work complete for tomorrow. They were given a wiki-ticket in class to make up missed work

Practice quiz announced for tomorrow on Measurement. Actual quiz on Measuring will be on Thursday.

Today we went through all the possible answers to yesterday's measurement lab. Even if the volumes change, the tools would still show the guess spot in the same place value. For example, if the range is from 70-80mL, a possible estimate is 7__4__mL. The guess digit is in the ones place. If we dump out some water and our measurement falls within a new range of 50-60mL, a possible estimate is 5__7__mL. The guess digit is still in the ones place!! Here are the possible answers to yesterday's lab. Check yourself and mark the number incorrect on your page.

We have changed the volume of water in each tool from yesterday. Today you will use page 5 in your packet to collect data in the lab. SKIP SECTIONS 12-17. Complete only liquid measurement. Directions: 1. Walk around and mark you water line on the tool in the picture for each station. 2. SIT BACK DOWN IN YOUR SEAT 3. Draw arrows to the lines outside each water mark. Figure out what the lines mean and report these two values as a Range under the picture 4. Estimate a value for the water mark. Your estimate must fall between the range you report. UNDERLINE the guess digit!

If absent today: Here are pictures of all tools. Look at each volume, mark the water line on the picture in your packet. Draw arrows to the range lines on either side of your water line. Report the range and an estimate for each picture. UNDERLINE YOUR GUESS DIGIT!!

= = =Monday, Feb 27: Connor P (2:33 came in with pass), Gigi A, Joseph D= First look at measurement lab. Mr. S passed out a piece of paper. Number 1-20 on this paper. Explore the 20 stations in the back of the room. Make measurements or answer the questions with the tools provided. Staple this sheet to page 5 of you packet. (The page with the tools drawn in on the packet) We went back through and explored a few ranges and measurement possibilities for numbers 1, 5, 6, 12, 11, 20 and 10.

Important things to take away from today: A measurement is an inexact number. Every time you use a tool there is error in measurement. You can report all the numbers you know for sure given the lines on a tool.... PLUSSSSSS one guess spot.

To explore measurement possibilities, you must first look to the range the measurements fall in. The range is the top line and the bottom line on either side of the desired measurement.

Here are some measurement notes that may help you for this topic: = = =Friday, Feb 24: Brandon K, Jadyn S= IF ABSENT DO THE QUESTIONS ON PAGE 5 BY YOURSELF. Copy the group conclusions listed below under YOUR response for each question.

10-15 minutes to answer the lab debrief located on page 5 in the packet. You must write a group response to all 4 questions.

One member from each group will put their answers to each question on the board. We will then discuss the similarities and differences in group responses and come to a class conclusion for each question.

Here are pictures of the group answers for period 6: PERIOD 6 Class conclusions: 1. Times became more precise. (closer to each other and more decimal places) 2.100m Tokyo had a tie and the 10000m didn't because it was a longer race so there is a greater margin between times and placing 3. because the times were closer in the 100 m, we need more precision 4.Yes, all tools lack precision, you must use a tool with capability to measure the desired need. **Write this under your group answer in your packet!!**

Write this under your group answer in your packet!! = = =Thursday, Feb 23: Shayna F, Alexis B, Jade O (Ex), Lexie Y,= Review of page 1 and 2 for period 6 Start of page 2 for period 9: Please see board notes below under Wednesday, Feb 22 below for what to write on page 2 in your packet!!
 * Here are pictures of the group answers for period 9: **
 * PERIOD 9 Class conclusion:[[file:pd 9 olympic debrief page.pdf]] **
 * 1. Times became more precise. **
 * 2. The 10000m was measuring a larger quantity of time, the margin was larger and needed less precsion **
 * 3. 100m: measured times that were closer to each other so more precise timers were needed **
 * 4. You need a tool that can measure your desired precision **

BOTH CLASSES: Computer activity for page 3 and 4. You will need to collect some data!! As you finish looking up data, you will be assigned to a group after Mr. S inspects your data charts on page 3 and 4 of the packet. If time permits, you may have gone to the lab stations in the back of the room to start the "Lab Debrief:" page in the packet. You must come up with these answers as a group. Tomorrow: each group will put their answers to each question on the board. We will then discuss the similarities and differences in group responses and come to a class conclusion for each question.

This activity should begin to make you think about units for measuring time. Different tools with different capabilities can be used to measure different circumstantial data. The IS a DIFFERENCE in the measurements 125s and 125.00s (that question on your pretest!!) = = =Wednesday, Feb 22: Shayna F, LeeAnn G, Jade O (Ex),= Hand back pre-test. This is not a grade that will count towards your average. It is however, questions that you are expected answer correctly AFTER the content from this unit is taught by Mr. S. Pay attention to where you missed the mark. Think about these questions as we go through material.

New Packet handed out for chapter 2: This is not the same packet that is located above at the top of the page!

Board notes and topics covered on first two pages of new packet: Went through the new packet pages one and two. See the above PDF for what needs to be written in your packet. Main ideas: 1. Tools can measure things with more certainty. Measurements can be more precise or less precise depending on the tool used. Estimating without a tool has no certainty. 2. Accuracy is how close something is to the target Precision is how close repeat attempts are to each other (Precision of a tool means how many places it can measure)

= = =Tuesday, Feb 21: Shelby S, Amarie S (ESL), Jade O (ESL)= Returned chapter 1 test. returned chapter 1 packet. Egg-speriment or make-up lab grade is returned with chapter 1 packet. Chapter one class participation points were also entered in computer. Think about your behavior and if you are positively or negatively affecting class.

Pre-test Chapter 2- this counts as a participation grade More inquiry activities will be used to teach the material on the pre-test. After the activities are complete.... you will complete a post-test that will count as a quiz grade. We can then show your progress throughout the unit. The post test will be the same types of questions, with different data, or differently worded questions covering the same content.

If absent: you will still complete the replacement activity, but you will not lose your check.

If present: We have a problem.... and angry teacher who will let out anger in the process of throwing eggs to break them!! You must prevent the eggs from breaking when thrown.

Think about constants and variable in this experiment. A constant is something that is the same for ALL people completing the experiment. Variable are things that are changing from person to person or throw to throw.

Controlled experiments can only have ONE variable. If more than one thing changes, how can you decide which had more influence on the result?

If we were to complete this same experiment again. How could we modify it? Would you do the same thing? Would you use the same materials? We will use this information to answer question sheet on Monday.

Upcoming events: Monday: practice elements #1-30 Tuesday: Actual element quiz #1-30 Wednesday: REVIEW OF CHAPTER Thursday: CHAPTER 1 TEST, CHAPTER PACKET DUE TODAY All pages must be complete in the packet. Extra credit vocab is available. The egg project or replacement activity question sheet should be attached to the end of your chapter 1 packet. = = =Thursday, Feb 9: SNOW DAY NO SCHOOL= = = =Wednesday, February 8: Shelby S, Leeann G, Kevin A, Amarie (came late), Joseph D, Cara W, Kaitlyn K, Brenton K, Aaron B= Collected syllabus agreement!

Review on VACUUMS? How do things fall in a vacuum vs from the roof of a building? Review on Questions science CAN and CANNOT answer? what is a system? 3 Branches of Science: name them!

Practice element quiz #1-20. ACTUAL ELEMENT QUIZ TOMORROW

CLASS **//DISCUSSION//** ON EXPERIMENTS: What is an experiment? How can we control an experiment? We can't just change a bunch of stuff and know for sure what has an effect on our result. In order to have a controlled experiment, you need to approach it systematically. You have to measure the effects of one thing before you can change something else!!

Look at page 3 and try to answer the questions. PAGE 3 ANSWERS: 1. B 2. H

Think about this... On Earth we can put things on a scale and get a mass. NASA has a problem. In space they can't measure mass because there is no gravity. The objects will not push on a scale. This is a problem NASA must solve. It is an **observation.**

How can they solve this? Now they have to test this. This is an **experiment**. After they experiment, they get results to **Analyze**. Did the scales work? Are they accurate? Can they be better? This is called a **conclusion.**
 * Hypothesis**: they think they can measure mass by measuring the force exerted when an object moves in an "If, Then" statement: "If the new scale displays an accurate mass when tested, Then the scales work".

If the conclusion is that the **hypothesis is right,** they **repeat** it to make sure it will work again. If the conclusion is that the **hypothesis is incorrect**, they go back to the drawing board and **revise the hypothesis.**

Yesterday's activity was discussed. As promised, Brian Cox visits the world's largest vacuum chamber, was shown on youtube. []

This shows a bowling ball and feathers falling from the same height outside and inside a vacuum. Inside the vacuum, the air is removed. There is NO air resistance. The feather and the ball fall at exactly the same time.

On a similar note, terminal velocity was discussed and demonstrated through a youtube video. (search: mythbusters penny drop) []

Here are the notes for pages 1 and part of page 2 in your packets. This is what will be checked for packet participation points. Please copy the right answers!! On page 2 we discussed questions that science can and cannot answer!!!

Finishing the day we took a sample element quiz for 1-10: Here is a copy: The key to the element quiz is ATTACHED above in the same pdf.

Actual quiz will be on Monday, using this same format. It is NOOOOOT matching!! The elements and symbols will not be in the same order! If you are absent today... you are STILL TAKING THE QUIZ. Quiz dates were announced last week!!!!!!

Pass out chapter 1 packet, if time permits. Go over storage procedure and how to enter the class protocol. start chapter 1: exploring gravity

Page 1: Fill in an answer to the first question at the top of the page. How is science part of your life??

We did the activity on page 1, but didn't write anything down. Two expo markers taped together feel at about the same time as one expo marker. Two expo markers fell faster than a piece of paper.

Conclusions: GRAVITY IS CONSTANT. AIR RESISTANCE AFFECTS BOTH OBJECTS In a vacuum, ALLLLLLLL THINGS would fall together. Gravity is constant, and air resistance is removed!
 * Things can fall at different speeds depending on their mass and surface area.
 * A 1 pound copper ball would fall differently than a 1 pound copper sheet that has been hammered into a very large thin sheet of copper, even though they weigh the same.**

= = =January 13: Johnathan V, Tatiana V, Nestor M, Nick M, Loren R,= Explain activity on Page 20. When positive ions come in contact with negative ions, they form neutral compounds. NEUTRAL MEANS NO CHARGE. You must have the positive cancel with the negative. In some cases elements like sodium and chlorine form a positive and negative one ion. They make a perfect match.

When you have something like Al 3+ and Cl -, you would need 3 Cl - to cancel the ONE Al 3+.

Today we will follow these directions to make compounds with the charts on page 20. There is an extra if you mess up. Glue the resulting compounds to a graph paper and staple to your packet.

Predict the charge make-ups.

We don't have a lot of room to make an actual model. We will staple the graph paper methane molecule into the packet. You must still answer the questions on page 6 for credit for the methane molecule lab grade. If you are not complete we will finish on Monday. The circles take a while to cut out!

= = =January 5: Brad S., Xavier H, Henry G, Anneliese T, Johnathan V, Nick M, Simon K= Review page 4. Finish notes on page 3. Complete practice on electron dot diagrams. Take two practice quizzes on energy level diagrams, and electron dot diagrams. The quiz will be combined tomorrow.

YOU WILL NOT SEE CIRCLES OR A CHART WITH #1-8. You will be given a periodic table to find the elements. You will then have to decide if you need to draw circles of energy levels with ALL electrons (energy level diagrams)... OOOORRR You will decide if you need just OUT ELECTRONS ONLY. The number of dots match the group number at the top of the column.

PLEASE DRAW DOTS IN THIS ORDER: TOP< RIGHT< BOTTOM< LEFT, like points on a compass. Move clockwise! Dots not drawn this way WILL be WRONG!

Start to think about methane molecule, page 6. Carbon's electron dot structure is unique, because it can either gain OR lose electrons to become more stable. It is half way to both. Hydrogen's electron configuration is similar that is is half way to full as well! Look at these and think about how they can make the perfect match!!

We will put together 4 hydrogen atoms with one carbon atom to make methane tomorrow after the quiz. We will have to cut our protons, neutrons, and electrons to fully represent the atoms! Methane molecule quiz on January 10! = = =January 4: Justin C, Henry G, Chris H, Joseph T, Johnathan V= Finished the bottom of page 1 up to and including all of page 2. Page 1 paragraph 6: lowest, greatest, strongly Write At the bottom of page: attraction is like magnets. The farther away the less attraction. Closer magnets pull each other!

Page 2: para 1: protons, electrons, Para 2: ONE

Bottom of page 2 notes and page 4:

Quiz on Friday having BOTH energy level diagrams and electron dot diagrams. Know the maximum number of electrons per energy level up to level 4. Energy level diagrams show all electrons. Electron dot diagrams show only the outer electrons. The number of outer electrons match the group number on the periodic table!!! (He*exception) Elements will either gain or lose electrons to become more stable (unless they are already stable {noble gases}). You need to see if their outer electrons are closer to 8, then they will gain! If they are closer to 0, then they will LOSE! gaining electrons makes you negative, losing electrons makes you positive!

We completed the first page of the practice quizzes on ENERGY LEVEL DIAGRAMS with the questions:

Make sure page 1 is complete! Finish physical properties lab on page 3 and 4. We discussed as a class our observations. There are certain things that MUST be included in each observation for full credit! This will count as a lab grade, not part of the packet grade! Make sure your observations are descriptive! You can look to make your own observations, at the pictures posted from YESTERDAY! I f you look at this and copy it word for word from someone else, you will get NOOOOOOO credit for the lab.

The actual quiz is tomorrow. Test for the chapter will be Thursday. = = =October 5: Justin C, Brianna D, Nick M= What is a significant digit? Page 2

An answer in calculations using measured quantities must reflect the error/precision of the tool used to make the measurements.

You cannot use a bad tool, for example something with a range of 0-100mL and report and answer to 33.3333333333ml. If the tool used only has one significant digit, the answer must reflect the error in the tool.

Adding and subtracting is easy if you know what a decimal place is... the number of places (count them) after the decimal point shown. See rules on page2 :

Quiz Friday on SD AND SD in math using addition and subtraction. If you learn the rules for multiplication and division on your own, you can receive extra credit on the chapter test and also in the packet! See the very bottom of page 2.

Start of page two. We filled out questions science can and cannot answer, and then we talked about systems. We discussed systems in the picture of page two, systems in the body, and other types of systems. Practice element quiz tomorrow! Keep studying and keep bringing in boxes. BOXES ARE DUE BY FRIDAY!!! = = = = =June 9 and 10:= DO NOT REPORT FOR SCIENCE FINAL ON THE 15th!!!! THERE IS NOT FORMAL FINAL OFFERED FOR THIS CLASS!!!!

Bonus Final: 100 questions TODAY AND TOMORROW ONLY! If you are not here, there are NOOOOOO makeups as this is a bonus opportunity. Students with a B or better: If you grade on the final is higher than your marking period grade, I will replace it with your final grade. Students with a C or below and passing: I will average you marking period grade and your final grade together for a new 4th marking period average. Students with an F have a chance to earn up to 15 points: A= +15 B= +8 C= +4 D= +3 F on final means no change to your grade.

If the final grade hurts you... it will be thrown out and not counted!! = = =June 8:= Last test of the year. Chapter 6 (82 points) Packets collected for a grade. (35 points)

= = =June 7: Laci, Baltazar, Chris, Shydon, Sheyanne, Alyssa, Kevin,= Played kahoot and made sure packet was up to date. Last test tomorrow. Bonus final offered in class on thursday and friday. If you are not here... you DO NOT get to take it! Packets due tomorrow too! = = =June 6: Laci, Alex, Jae B= Methane molecule quiz (30pts). Went over predicting charge using electron dot diagrams. If something has less than 4 dots it will lose electrons and become positive. If something has more than 4 dots it will gain electrons and have a negative charge the same size as the number of single dots in the structure (to get to 8!!). Test format is listed in PDF below along with the answers to page 23: = = =June 3: Laci S, Dakira= Took a practice methane molecule quiz. Quiz will be on Monday!! Some previous packets were passed back if you would like to study for the Bonus Final. Chapter test is one Wednesday.

You need to get the notes we wrote on the board.

Packet is also due Wednesday. Pages 5, 7-10, 16-21, and anything after page 23 will not be graded!! BONUS FINAL IS THURSDAY AND FRIDAY.... If you are not here, there are NOOOOOO makeups as this is a bonus opportunity. Students with a B or better: If you grade on the final is higher than your marking period grade, I will replace it with your final grade. Students with a C or below and passing: I will average you marking period grade and your final grade together for a new 4th marking period average. Students with an F have a chance to earn up to 15 points: A= +15 B= +8 C= +4 D= +3 F on final means no change to your grade.

You may chose to not take this final. It cannot hurt you in any way... so you may as well give it a try!

= = =June 2: Laci S, Shydon, Jae, Kevin, Sheyanne, Alyssa= Took quiz on energy level diagrams showing all electrons, and electron dot diagrams showing only valance (outer) electrons for 25 points.

= = =May 13: Baltazar, Kyle M, Julissa, Shydon, Alyssa, Tiara, Keairah,= Watched this YouTube video and filled out a question sheet. This will be worth 10 points in your packet grade. Make sure you complete and it and staple it TO THE BACK of your packet. https://www.youtube.com/watch?v=kL5xGQUiAxQ Here is the question sheet: = = =May 12: Laci S, Alyssa, Cory H, Julissa, Tiara, Jessica= Reviewed the difference between physical and chemical property again. We also talked about physical changes versus chemical change. Chemical change rearranges elements and breaks bonds allowing new things to form. You start and end with things that are much different from each other chemically. Physical changes start and end with the same material chemically. You may change the shape size or state, but not the compound itself!! Here are some clips that demonstrate the bottom two signs of chemical change that we listed on page 11: https://www.youtube.com/watch?v=BGUfC3UUBkI https://www.youtube.com/watch?v=AO67MnZaAvQ https://www.youtube.com/watch?v=MyAzjSdc3Fc https://www.youtube.com/watch?v=2pXyJ7P0B0k https://www.youtube.com/watch?v=FOeH29hlHlU https://www.youtube.com/watch?v=znsPa1BSaIM

Usually a chemical change exhibits multiple indications at the same time. Showing ONLY ONE indication of a chemical change can often be a tricky physical change example !!! salt dissolving shows color change, but that is it.... it is physical a blue solution plus a yellow solution shows greeen... but that is it... it is physical water freezes, shows change of state... but that is it... YOU TOOK HEAT AWAY... it wasn't like the water just naturally freezes because it is reacting with something!! that is physical. = = =May 11: Corey R, Dracon, Alyssa, Cory H, Julissa, Kevin= Went over answers to page 7: 1. sparks of a chemical reaction 2. Yes, matter can neither be created nor destroyed 3. nothing On page 8 review the definitions of a chemical property. The major difference between a chemical and a physical property is that a physical property can be seen or measured without a chemical reaction. Physical properties include color, temperature, density, odor, etc. Chemical properties cannot be seen with our eyes or measured without changing the substance in question, such as flammability, toxicity, or reactability. We filled in the bottom of page 11: 4 clues to hint for chemical change: 1.color change and new substance (not a blend of the original two colors) 2. formation of a gas (without added heat) 3. Spontaneous temp change or energy production (without added heat) 4. formation of a solid from 2 liquids.

We watched chemical reaction clips that show the first two indicators of chemical reactions: https://www.youtube.com/watch?v=OPTdAmSx4m4 https://www.youtube.com/watch?v=xK4z_YhtTBM https://www.youtube.com/watch?v=OKurcQt3ZOU https://www.youtube.com/watch?v=U5oBfl1QD_g

= December 16: Asheel = Packets due tomorrow. The only thing that should be empty is page 10. Everything else should be complete. Here are some answers to things we did in class... Kahoot Day

You will need to remember the maximum amount of electrons in energy levels 1-4. (2, 8, 18, 32) You have to know how many energy levels are needed for each element, and if the levels are full or not. You also have to know if they will lose electrons or gain electrons to become more stable. You will also be required to draw electrons in the appropriate energy level on a quiz TUESDAY JANUARY 5!! We will take a practice quiz tomorrow. We entered pictures and electron distribution for page 2 for elements H, He, Li, O, Ne, Na, and F:

=December 23:Aansa, Aseel= Practice quiz on electron distribution for TUESDAY JANUARY 5: Finished page 3 and 4 in packet. Quiz Wednesday will be on material up to page 4... mostly electron dot diagrams.

=J= Returned quiz from yesterday and reviewed energy level diagrams (WITH CIRCLES). Took new quiz (10 points) on energy level diagrams versus electron dot diagrams. Electron dot diagrams ONLY COME FROM THE GROUP NUMBER ON THE PERIODIC TABLE. We then finished our methane molecule project. There is a quiz on the methane molecule project where you will have to identify a covalent bond, carbon nucleus, hydrogen nucleus, hydrogen atom, energy levels one and two. There will be a matching word bank and you will be given an accurate picture of a methane molecule. On the other part of the quiz you will have to draw energy level diagrams for both Hydrogen AND carbon, you will then have to list the number of protons, electrons, energy levels, and full energy levels for each atom. Here is a picture of what you should have to get full credit for the methane molecule assignment. It will also help you study for your quiz.

packet due Wednesday. You should already have complete pages 1-5 (no questions on page 5) and 11-15. Yesterday and today should have been enough time to finish page 17-19. There are no instructions on page 17.... see following pdf file for directions and examples. Tomorrow (Friday): complete page 22-24, 29-30. Pages 31-32 will be extra credit. Also to be turned in with your packet is your methane molecule activity and your ionic compound color/paste activity. As a whole, this work will be worth APPROXIMATELY 90 points!!! The test on Wednesday will be 100 pts!! Check out this board work:
