Text: pages 376-401 7-10 day unit.
Objectives
After completing this section, students will:
1. be able to compare and contrast solvent, solute and solubility,
2. be able to compare and contrast unsaturated, saturated and supersaturated solutions,
3. be able to compute and express the concentration of a solute in 3 different ways,
4. be able to construct and interpret a solubility curve.
Activities
1. A lab in which the solubility of salt and sugar are compared.
2. A worksheet on determining molarities of solutions.
3. A worksheet on determining the mass of a substance needed to create a solution.
4. A worksheet on dilution.
5. An activity exploring ppm concentrations. Also a set of problems on concentrations.
6. An extra credit internet lesson. Here is the worksheet.
7. A project in which the student brings in a sample of a soluble and insoluble substance from the kitchen.
8. A lab in which a solubility curve for sucrose is created.
9. An evaluation whereby an unknown substance is identified by its solubility curve.
