7th Graders Learn About Gravity

Mr. Johnson led his 7th grade students in a demonstration about gravity. The blanket is a representation of space and time. Einstein's theory is that by adding mass to space, that mass will then warp space and time creating the gravitational attraction toward other objects. When adding a heavy ball to the middle of the blanket it creates a steep angle which then attracts the rolling marbles and shows us how planets then revolve around a larger body such as the sun. The more massive the object is, it creates a steeper angle and more attraction than lighter or less massive objects. #PCMSproud
