In science co-op today we all learned a little bit about structures. The kids started off with some building of Lincoln logs, and then moved onto play dough structures.
There was a 'contest' to see which team could build the highest free-standing tower
and then an experiment to see which shape (circle, square or triangle) was the strongest by balancing books on top of a paper tube of various shapes to see which could hold the most weight (very interesting!!)
The grand finale was a talk about weight distribution, and the kids all had a chance to stand on top of a platform of Dixie cups.
