Sobre este recurso...
Gravity is a force that all objects exert, but you can really only feel it from the really big things. The Earth pulls us down to its center, the Moon pulls our water from the oceans to make the tides, etc.
With this experiment you’re going to see what gravity can do to a stream of water as it falls.
