Big idea: Making s'mores can help us understand chemical equations and the calculation of masses of reactants and products.
1. Warm-up: Masses of a reactant problem (see Dr. Rico's warm-up booklet).
2. Review the calculation of mass for either a product or reactant: do problems #7, 8, and 9 from the Chem Calculations worksheet.
3. Go over the S'mores "Lab" worksheet. Explain concept of making s'mores, and the relationship to chemistry.
4. Hand out materials, have students hold up reactants and products.
5. Do calculations on worksheet.
(Note: quiz for today postponed until Monday.)
Homework: see pink sheet next to white board in Room 1006.
