Chemical Reactions in Year 5 Science 30 Apr 2019

When a soluble Vitamin C tablet is dropped in water it begins to dissolve and a chemical reaction takes place whereby carbon dioxide gas is  released.

If the tablet is dropped in water inside a 35mm film canister and the lid is put on, gas builds up inside the canister until the pressure becomes so great that the lid of the canister pops off.

Children investigated a range of variables which could be tested using this science, such as:

How does the temperature of the water affect how quickly the canister pops?

How does the amount of tablet affect the height that the canister travels when it pops.

How does the amount of water affect the distance the lid of the canister travels when it pops.

The children had great fun and worked very scientifically to gather and interpret data.
