Today in the learning street we had a Science Roadshow. It was really fun and we got to do some experimenting. The first show we saw was the the fire and ice show. It started off to be about fire and ice, then we went to temperature and there was a metal hoop and it could fit a ball through it, then when you put it in liquid nitrogen the ball could not fit anymore. The reason is because when the metal is cold the metal got smaller because of it molecules and when it gets warmer it gets bigger because the molecules spreading out. Then we went on with experimenting. 
The people who were in charge of the Roadshow was Shane, Samantha and Dave they were the ones who done the experiments. here are some more photos :D
It was really fun doing the experiments I really enjoyed it :D
Have a nice day.
BYE!
