I used to teach a sculpture project with 5th graders that was so popular that a few middle school kids would come back on their own time to make them when I was teaching the unit--Fuzzy Monsters. It was basically a variation on a wire sculpture that resulted in a fully movable furry monster that reminded me of Muppets. This was one of my most popular projects, and often requested by incoming 5th graders. I had the middle schoolers who were interested make their monsters, and because they were fully movable, we would make stop action films with them. I have shared the plans for these monsters before on this list, and will again if you are interested. You may have to wait a little--we will be gone for around a week for the holidays, and away from my computer.
