Explosive Science in Tamar Class 2 Mar 2020

HWhen a soluble vitamin c tablet is added to water, an irreversible change takes place and a carbon dioxide gas is created.
Year 5 used a 35mm camera film canister, added water and added the tablet and put the lid on. The resulting build up of pressure makes the canister ‘explode’ and the rocket travels.
Year 5 have been investigating factors that can affect the distance a rocket travels, or the time it takes the rocket to launch. They changed one factor (independent variable), kept all other factors the same (control variables) and measured the dependent variable (distance or time).

Year 5 are becoming expert scientists and it was a pleasure to see them collaborating so effectively on such an exciting science investigation .
