About six weeks ago, our class did the CSIRO. The thing our class was going to do was science with a scientist. The first thing we were going to do was how to produce electric from an orange, but the scientist did not have an orange so we used a potato instead. To do this , we had to use these little machines to with plugs and put the plugs inside the potato.We looked at the numbers on the machines to see if the potato was producing electricity to the little machines. after we done that , our class was split into groups and we did other scientific things.
