This idea was brought to the children's attention through a bit of discussion, reading, and experimenting. I first asked everyone what they knew about gravity. Most children knew about it in the context of their world, but weren't thinking of it as a scientist yet.
We talked about how objects fall to Earth. We talked about how everything has gravity, and only the really big objects (like planets or moons) have gravity we can feel. We talked about what the world would be like without gravity. We talked about how gravity feels different in different places. We even did experiments to see how different things fall and why they fall that way.
Through all of this we learned.... Gravity is a force that pulls things toward Earth.
