Tonight we brought the Coooperation Pulley Exhibit which was well received by the kids and parents alike. It's a fun exhibit where 3 people have to work together to raise and lower a basket with pulleys, hence the name Cooperation Pulley. It's great to hear kids working with each other and their families and thinking about how it works and what to do with it. The Earthquake Shake Exhibit also made its debut. Here kids try to build a structure on a small table that shakes. The point is to see if their structure will survive an earthquake. It was really interesting to see some of the structures kids and their parents came up with, and even more fun to watch as they tested the soundness of their structures.
