Law of Conservation of Mass

• When finished, read “The Right Man for the Job” on pages 260-265 in Story of Science (pink book).

• What happens to the mass before and after a chemical reaction?

• Who discovered this important concept? Where and when did he live?

• How does he prove that mass may be transformed but never lost? Describe what he learned from boiling water; weighing rusted iron, and burning a log in a closed container to measure the products.

12/10/12 Monday

• Entry Task

• In your own words, describe “Law of Conservation of Mass.” You may use the book to assist you!

• Discuss reading and questions. • Watch video of chemical reactions and take notes in

your notebook. • Watch clip of Lavoisier at work…• Finish ESSAYS!!

12/11/12 Tuesday

• Entry Task

• If you conducted a chemical reaction in a closed container, would any of the mass be missing after the reaction?

• Review safety procedures for lab work. • Glue lab sheets on next two pages of

Conservation of Mass Lab

• Your group will need a beaker, alka seltzer tablet, a plastic bottle with a tight lid, a graduated cylinder, access to a mass balance, and a lab sheet 25.1.

1. Find mass of tablet, beaker with 50 mL of water – DO NOT MIX.

2. Mix tablet with water in beaker – after reaction, find mass.

3. Calculate change in mass. 4. Finish notes.

5. Find mass of tablet, bottle and lid with 50 mL of water – DO NOT MIX.

6. Add tablet and QUICKLY put lid on. 7. Find mass after reaction is complete. 8. Open the bottle. 9. Find mass of bottle, solution and lid. 10.Calculate change in mass. 11.Answer questions on the back.
