I was looking for some educational material to teach angular momentum to 1st-year students. However, I didn’t manage to find OER suitable for my needs. No problem with that, two possibilities: my search was not so smart or there is a place that has to be filled.

So I decided to start wondering and thinking of new ideas to engage students in active learning processes concerning rotations of rigid bodies. At the moment I have designed a low-cost Rotation-Gym, that can be a good environment where to explore and discover physics laws about whirling rigid bodies.

This is the beginning, let’s see what happens.
