Year 4 and 5 Science

4H had great fun making water filters in science yesterday, as part of their work on separating techniques. Meanwhile, Year 5 are investigating the reaction between acids and alkalis (in this case, vinegar and bicarbonate of soda). They learnt first-hand how it can produce enough carbon dioxide gas to pressurise a film canister and launch it 30ft into the air! A great few days of practicals with Mrs Layfield.
