Science projects

After we were done watching the little program Shaun and his partner let us go and try to figure out the projects that the other school built. We were given a card that had the projects name on it and we had to go and figure out how the thing worked. After we were done finding what we had to do when then had to go to any of the teacher that were there and then I we had to tell them how do we know what it does and they would clip the side of the card so they knew that we wen't cheating.
