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.

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.
