I love this video which is from the science classroom on PBS. I love the little girl who explains that they have to work “real hard” and the one who notices that the water gets through the cracks, and especially love the kid who says that he’s using mud like glue because that’s “what beavers do”. I read that Massachusetts Audubon lets kids build a beaver dam on their beaver field trips and I wrote their project coordinator for information about how it works. She says they love to use a tiny natural stream, small enough to hop over, but if one isn’t available they will just pour a bucket of water on the experiment and see how it holds up! Unfortunately the video wouldn’t let me embed it so I’m risking the long arm of the law and posting it on youtube to share. Which means you should DEFINITELY watch it before PBS throws me in the pokey for copyright infringement. Let’s puzzle together to think how this might be replicated at the festival okay?
