We discussed the concept of gravity. We let a few things drop to the floor to show how gravity works on Earth. We viewed a Magic School Bus video that showed how the force of gravity works on a "planet". If the planet is larger in size, it will have a greater gravitational pull. If the planet is smaller in size, it will have less of a gravitational pull. Lastly, Libby drew a picture to represent a planet with and without gravitational pulls.
