We have been experimenting with different ways of propelling objects. Our first experiment was with denture cleansing tablets, water and balloons. We discovered that the tablets reacted with water and made a gas which inflated the balloon. This is what happened.
We tried putting a tablet in a film canister with water and putting the lid on. Some reacted quickly but others had a wee while to wait!
Love the science video clips...experiments are such good fun!It is exciting to watch them as they happen.

It is great seeing these science experiments on videos - they will help you to remember what happened. Some of the lids on the film jars went off very quickly with quite a bang!
ReplyDeleteI am sure you are learning lots form doing these fun experiments. Mrs Miller
