Science Roadshow

Today my class, 7tz and I went to a science roadshow in the learning street plus the 3 science labs. First people from the science roadshow company introduced themselves and the helpers. The people running the science roadshow were Shane, Samantha and Dave. The helpers were years 9 & 10. After introducing themselves and the helpers they showed us some different experiments. 4 peoples volunteered and the people were Me, Kody, Tukotahi and Malakiah. There were heaps different experiments. 

I volunteered for the first experiment which was used with liquid nitrogen. I hold a black number 8 pool ball and dropped it into the metal hoop 3 times with no struggle. Then Shane put the metal hoop into the bottle of liquid nitrogen for about 5 minutes. While the metal hoop was sitting in the bottle of liquid nitrogen I was putting on safety gear. The safety gear I was putting on was gloves and glasses. I came back up and Shane took the metal hoop out. I dropped the black number 8 pool ball in the metal hoop 2 time with struggle. I pushed down 2 times also with struggle.

We had about an hour to try out the different activity. There were 70 different experiment set up for us. My favorite experiment was the swirly chair that you hold 2 medium heavy sticks. If you made your body smaller you will go faster. If you made your body bigger you will go slower.
