The Science Road Show!

What: I went to the Science Road Show! The Science Road Show is a fair that's all about science and, fun. When we went inside it was really cool and there were a lot of activities. One of them was the hovercraft. It was really cool and you got to ride the actual hovercraft, and there was a man who did the elephant toothpaste experiment. There were two hosts, and they explained how dry ice turns straight away in to a gas.

So What: what I learned from the event?!? I learned that there is a process for when there is a liquid and if you freeze it it will become a solid (ice) and if you heat up the liquid it becomes vapour. There is also another experiment which is when you have salt water and you put it in the the Suns heat it will make vapour and then you will have salt crystals left in the container that you put it in.

Now What: How I could use my prior knowledge and my new knowledge to make connections. I already know that how to make elephant toothpaste, and how to make salt but I didn't know how dry ice instantly turns into a gas instead of becoming to a liquid then a gas. So all these thing I learned I could use in my I Explore or for my future.
