With my first grader, I have been teaching about the weather. They have the typical weather vane that you make from a straw, pencil and paper. I wanted it to be more exciting. We made this one from junk we found in our barns. It took a little bit of engineering and rigging, but it actually turns. We used PVC piping, metal scraps that we found, a long nail, washers and a metal hose fitting. The girls painted it funky colors, and now it sits on a post near my pasture.
