Building a beaver dam

Little Man is really enjoying his book about beavers this week, so we went out after the rain and built a beaver dam!  He gathered sticks and rocks and made a (tiny) functioning dam.  We spent some time talking about why beavers build dams (to create ponds where they can build lodges to live) and the benefits of dams to the local environments.  We watched to see that the water on the other side was cleaner - the dam acted as a filter and sent cleaner water 'downstream'.  We had a lot of fun stopping the water and watching it move faster when we let it go and then finding ways to measure how fast the water was moving (we ran along side it).
