My class had Scientists in school on January 24 2012.
First of all, we talked about how structures stand.
Second of all, my group had to put animals on this thing and tell where the animals live.
Thirdly, we had to go to a different table at that table we tried to balance things on our fingers.
Fourth of all, we had to go to a different table again at that table we had to balance blocks to make a little brige
Finally, we had to make a brige and put three heavy books on it.
Most importantly our structure standed.
