Activity #17 Co2 From Alka Seltzer
Pupils observe what occurs when Alka Seltzer tablets are added to water. They explain why water stays in the jar when it is above the surface of the water. Pupils test for the presence of carbon dioxide by conduting the match test.
Curated OER
Alka-Seltzer Cannons
Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...
