Product Description
This engaging, hands-on lab will help your students to understand the law of conservation of mass, and can be done as an inquiry lab or as a traditional (post-instruction) lab.

Students perform three experiments: one physical change, one precipitation reaction, and one gas-forming reaction. In the first two experiments students find that mass is conserved, but in the gas-forming experiment it appears that mass is not conserved. Students are challenged to explain their observations.

This is also a great lab for challenging the deeply ingrained misconception that gases do not have mass!

Materials needed:
-beakers or plastic cups
-balance
-water
-sugar
-calcium chloride
-sodium carbonate
-Alka-Seltzer

The product preview shows the first two pages of the student lab, as well as some of the Analysis questions after the lab.
