Alka Seltzer Rockets
This activity starts with a discussion about chemical reactions. Observation is made of what happens when an Alka Seltzer tablet is placed in water. Each student makes and decorates their own Rocket from a film canister (unfortunately I cannot get more film canisters these days so they do not keep them.) I launch all of their Alka Seltzer powered Rockets which should reach a height of three metres.
Possible extended work: Rockets are made to suit various propulsion systems, i.e. air stomp, compressed water or air. Heights of trajectory can be 20 metres or more. Different height measurements are discussed then tested. Various flight stability devices can also be tested.
