Rocket Poppers Investigation

Last week,  Palm class completed their Effervescent Rocket Popper Investigation. The children investigated how the amount of effervescent tablet effected the speed of which the tablets reacted with water. 

The water reacted with the effervescent tablet causing a fizz as it produced carbon dioxide gas. When the lid was placed on the film canister (rocket) the gas became trapped and put pressure on the lid of the canister. As the pressure built up, the canister departed from the lid and shot up into the air. This is similar to the way that a rocket is launched except fuel instead of effervescent tablets and water are used.
