The science roadshow

Science roadshow

Yesterday room 4 went to Hasting intermediate and we went to the science roadshow. 
I learned about how much carbon dioxide you breathe out and a normal kid should breathe  out about 1.5 liters. 
I liked the uphill roller there was two bars, a coconut shape roller and a rolling pin. You put the rolling pin on the top of the bars and it would roll down then if you put a the coconut roller on the bottom and it would roll upwards. 
My favorite part was in the fire and ice show were Anna-Sophie had a candle and lit it and dipped it in kerosene and then sprayed the candle and it was like a fuel but when she dipped a match in a container of kerosene it went out because fire needs three things to keep it going oxygen, fuel and gas.
