On Tuesday 24th November someone came to our school to teach all the grades some science about heat. The man was called Charlie. He was a scientist so he would have known a lot about science. The best experiment was the one where we used a candle to make a wind mill go round and round. Also there were two experiments that the class could not do and they were where Charlie put two chemicals together and it created a flame and the other one was where he used something that blew hot air and it made a plastic bag fly.
