After building waterfalls outside (see blog post below), the students decided to construct dams to catch the flowing water. Then we got to talking about animals who build dams. We were on to beavers! We read books about beavers and then thought it would be fun to try to build our own beaver-like dams. We divided up into groups and constructed beaver dams with mud, twigs, straw, and leaves. At the end, we poured water into the constructions to firm them up. Birches students are really eager beavers!
