The See Saw in the Forest

These children were pleasantly surprised when they discovered this seesaw in the forest. They were all given the opportunity to jump aboard and try to teeter it back and forth. It was interesting to watch the children as they negotiated ways to make the log shift. The difficulty lay in the fact that the log was not evenly distributed on the fulcrum (although it appeared to be) therefore equal weight on either side would not move it. The weight needed to be heavier on the short side but could the children figure this out?
