Today at school, John came to talk to us about chemical science. We had to pretend we were in a glass and imagine we were atoms and we all had to join up to each other using our hands and we were a solid!!. Then John separated us into pairs and we could move more freely! We became a liquid!! Then he split us again and we were on our own, free to go anywhere... which made us gas!! So that's how we learnt the difference between solids, liquid and gas.
