Today we had a visit from the awesome people from ‘Science in a Van’. The morning started with some fun science tricks where there were 2 cups and a teapot and cloth underneath them. Emily had to pull the cloth underneath them so fast that the cups didn't move and she did! Allen had a board with four strings tied to it. He put a cup on it and said if he swinged it in circles the cup wouldn't fall of it. He swinged it in circles and it didn't fall! It was because the energy wanted to go the other way but the board kept on stopping it. He told us that without force nothing can be moved. Then he told us about the 5 senses and I got picked for one of the volunteers! We got blindfolds and he gave us an item that we had to say without seeing it. He also showed us some stuff with dry ice. He said never ever put dry ice in a sealed container. Then he put it in a sealed container and it exploded! Then Emily came back and showed us about the periodic table. Then I saw a can and it was smoking. She put it in a container of water and it imploded!
I learnt that there are 3 states of matter
Solid
Liquid
Gas
I also learnt about atoms. When the atoms join together they make molecules.
Another cool thing I learnt was that solid dry ice can easily be turned into gas but does not like to be turned into liquid.
I had a really great time watching ‘Science in a Van’. I learnt lots of new, interesting, information about states of matter and I would highly recommend it to anyone else who had the opportunity to watch it.
