The rocker
This is an experiment that requires collaboration. Can you find the equilibrium point of the plank or is it just fun to see-saw?
Finding balance on the Rocker can be a true team effort and it requires collaboration. Can you find the equilibrium point of the plank?
Many people have tried this on a normal see-saw. It can be slightly more difficult here since many people can stand on the Rocker, maybe as many as a whole school class. All these people are to collaborate to get the huge see-saw in balance.
