Finishing and Testing Our Beaver Dams

This week we finished building our Beaver dams out of twigs, rocks and mud.

Then we tested our dams. Each group presented their dam to the class and then poured water on the sides to see if the dam would keep the water from going through. Some of the dams were initially successful at keeping water from going through, but others were not. Our students were very excited to test their dams!

We told the students that we would look again on Monday morning to see what had happened!
