Our Second Science Discovery Day

Today we had our second discovery day.  

Discovery Time in Room 4
First we went to Room 4. Mrs Irwin gave us a toy car, a marble and a track. We rolled things off a ramp and had to see which went the furtherest and then we had to make a high ramp. Did it make the marble and car go faster? What happened?

                         

We found that the marble went further than the car did

Discovery Time in Room 1

In Room 1 we were doing kitchen science experiments. We were mixing baking soda and vinegar and making gas. We found that the gas blew up a balloon that was attached to a beaker and it also  made our ice blocks explode.

Then we put some tempera paint in a plastic bag, poured some vinegar into the bag and sealed it. Then we watched as the bag expanded and grew tighter and tighter. It was so exciting.

We also put some mentos into a coke bottle and watched to see what happened.
