Fun with Density in Y3/Y4 Science Club

On 9th December, children had fun learning about density in the Y3/Y4 After-School Science Club.
Several enticing experiments were undertaken. These included making lava lamps with oil, water and fizzy vitamin C tablets, extinguishing a candle flame with carbon dioxide gas, and making a Cartesian Diver rise and fall in a plastic bottle of water. – All of these experiments worked due to the differing densities of the ingredients involved.
