Curated OER
Alka-Seltzer Cannons
The scientific method is emphasized in this engaging and exciting chemistry activity. Learners get to create Alka-Seltzer cannons out of film cannisters, water, and Alka-Seltzer tablets. Carbon dioxide gas builds up inside the cannister,...

Alka-Seltzer Cannons
Fourth graders examine how to conduct a reliable scientific experiment so that the results are valid. They compare and contrast the reaction of Alka-Seltzer tables, one whole and one crushed, and time how long each takes to pop the top...

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...

Forces and Cannons
Students create an Alka-Seltzer cannon in this lesson plan. They explore the difference between balanced and unbalanced forces, and how unbalanced forces can cause motion. They then examine how a cannon works and create their own.
