Big idea: the pressure, volume, and temperature of a gas are related in clear mathematical ways. Can you calculate one, given the other two?
1. Warm-up: Given 100 g of NH3, how much NaOH can you make? TRY TO DO THIS WITHOUT THE CHEAT SHEET!!!!
NaOCl + NH3 --> NH2Cl + NaOH
2. Review website, note relationships from all the different demonstrations (balloon, syringe, crushed can, candle, love meter).
3. Review the Animated Gas Lab site.
4. Notes #17: The Gas Laws
Homework: 1) see Monday's homework.
2) Make sure all the worksheets from Packet #7 are finished:
a. Balancing Equations worksheets (2: Bal Equ and Another Bal Equ.)
b. Chemistry Calculations (one side is classwork, the other homework)
c. S'mores Lab (be sure you complete this, we did NOT complete it in class!)
d. Solutions worksheet
e. Kool-Aid calculations and sulfuric acid dilution calculation (on looseleaf)
f. Exploratory Gas Lab (on looseleaf paper, balloons, syringe, crushed can, candle, website)
g. Gas Laws worksheets

Monday, Dec. 15th: Kinetic Theory
Big idea: the kinetic theory of gas (motion related to temperature and therefore pressure and volume) can be used to explain things!
1. Review grades and grade sheets.
2. Quiz #12: Masses of Reactants/Products, Solutions, and Love Meter.
3. Remind students of kinetic theory of gases. Redo demo with hot and cold water and dye.
4. Crushed can demonstration. Explain what happened, using Notes #16.
5. Candle activity. Explain what happened, using the ideas from Notes #16.
6. Demo: website with changes in pressure, temperature, and volume. (Animated Gas Lab)
7. Assign homework, review big idea.
Homework: 1. Explain to someone how the love meter, the crushed can, and the candle activity work, and how they all relate to the kinetic theory of gases. Write what you say and 2 questions/comments from the person.
2. Trial 2 due Wednesday.

Friday, Dec. 12th: Intro to Volume, Pressure, and Temperature
Big Idea: When dealing with gases, the temp., pressure, and volume are clearly related.
1. Warm-up: Explain how the love meter works. Do last problem on quiz #11 as warm-up, too.
2. Collect homework, hand out graded work.
3. Go over Quiz #11.
2. Mini-lab: Balloon in hot and cold water, mini-marshmallows in syringe. What is relationship between temperature and volume? Between pressure and volume?
Homework: Get in late/make-up work! End of time for progress report.

Thursday, Dec. 11th: Introduction to Gases
BIG IDEA: Molecules move!
1. Warm-up: determine molarity if given 20 g of NaCl in 50 mL of solution.
2. Practice with these kinds of problems.
3. Hand out Love Meter and make guesses on how it works.
4. Notes #16: Molecular Motion
5. Explain how love meter works.
Homework: Make up 5 solutions problems like the warm-up, solve them.

Wednesday, Dec. 10th: Practice with Making Solutions
BIG IDEA: You can calculate the molarity of a solution, and make solutions of a particular molarity!
1. Warm-up: how many grams of Sr(NO3)2 needed to create 100 ml of a 2M Sr(NO3)2 solution?
2. Practice with problems in making different solutions of things we’ve used in the classroom: 3M NaOH, 8M HNO3.
3. Short lab: have each lab group make different concentrations of Kool-Aid: 0.01 M, 0.1 M., 0.25 M., 0.5 M., 0.75 M., 0.9 M., 1 M, and 2 M. Line up the different molarities to see if they were done correctly.
Homework: 1. Make up 3 solutions problems where you provide the molarity (M) and the amount you want to make, and then find the # of grams you need to do it.
2. Quarter Project, complete Trial 2 by next Wednesday.
