Friday, Nov. 21st, 2008: Molar Mass

BIG IDEA: You can count the number of molecules in moles and convert them to a mass to weigh out and look at!

1. Warm-up: Name the four macromolecules and their subunits, and three properties of an acid and a base. Then balance this equation: NaCN + CuCO3 --> Na2CO3 + Cu(CN)2.
2. Turn in Packet #6. Write down homework for over break.
3. Practice balancing equations with "Another Balancing Equations worksheet."
4. Notes #13: Moles and Molar Mass.
5. Practice with Molar Mass.
6. Quiz #10.

Homework: 1. Complete Trial 1 for your Quarter Project.
2. Write THREE quizzes for your partner, and email or mail them off. Do their quizzes. Q#1: Notes 1-5. Q#2: Notes 6-10 Q#3: Notes 11-13.

Thurs., Nov. 20th, 2008: Balancing Equations

BIG IDEA: same as yesterday.

1. Warm-up: Explain how an acid and a base can degrade a protein.
2. Review the warm-up.
3. Hand out homework worksheets
3. Notes #12: Balancing Equations.
4. Practice with Balancing Equations (worksheet).

Homework: 1. Complete Counting Atoms worksheet and Balancing Equations worksheet.
2. Finish questions for Lab #7; Packet #6 will be due tomorrow (Friday).

Wed., Nov. 19th, 2008: Introduction to Balancing Equations

BIG IDEA: Matter cannot be created or destroyed, only recombined. Balancing equations is one way to demonstrate this idea.

1. Warm-up: draw the Lewis dot and structural formula for CO2 and H2O.
2. Review the warm-up.
4. Check results from Lab #7; answer questions.
5. Debrief Lab #7: Organic Molecules in Acids and Bases
6. Introduction to Balancing Equations: Demonstration of counting atoms and simple balancing equations. Counting Atoms Worksheet.
7. Counting Atoms: Practice with balancing equations.

Homework: Counting Atoms Homework worksheet

Tuesday, Nov. 18th: Organic Molecules, continued

Big Idea: Organic molecules make up all living things, and are made of subunits.

1. Warm-up: Draw the structural formula and Lewis dot structure for AsHCl2.
2. Go over Notes #11: Organic Molecules again
3. Review acids and bases and how they affect organic molecules.

Homework: none. There will be double for tomorrow, since none today.

Mon., Nov. 17th: Organic Molecules

BIG IDEA: Organic molecules can be degraded by acids and bases. Can you explain in general what happens when you are burned by an acid or a base?
1. Warm-up: Draw the Lewis dot structures and structural formulas for the following molecules: N2H2, C2H5OH
2. Collect homework/assign new homework.
3. Review acids and bases, and the lab
4. Make hypotheses for Lab #7
5. Run Lab #7: Organic Molecules in Acids and Bases
6. Review Big Idea, remind them of homework.

Homework: 1. Start your Trial 1 for your Q2 project. 2. Counting Atoms Classwork sheet.
