This term, Year 4 have been learning about States of Matter. To investigate this further, we set up two experiments. Firstly, we poured popping candy into a bottle of coke and put a balloon on the top of the bottle to see what would happen. Secondly, we poured baking powder and vinegar into a bottle of water with a balloon on top and shook it. We were amazed to see that, in both experiments, the balloon inflated! Can you explain to someone why this happened?

Here are some photos from our experiments- look at the joy and wonder on our faces!
