Gravity


More fun times in science. We predicted how far up the 'hill' our balls would travel, and tested our predictions.

These videos were taken during science while we were studying simple machines. Each group would change the location of their fulcrum and then guess how big the force (paperclips) would have to be to lift the load (an eraser) on the other side of the fulcrum.
