Students will learn about gravity as they build this counterweight system to move an apple. The gravitational force exerted by the Earth pulls objects downward. Using this principle, students will create a device to move an apple up a ramp without touching it.
This resource is aligned with the following standards:
NGSS 5-PS2-1. Support an argument that the gravitational force exerted by Earth on objects is directed down.
Utah SEEd Standard 3.3.3
Construct an explanation that the gravitational force exerted by Earth causes objects to be directed downward, toward the center of the spherical Earth. Emphasize that “downward” is a local description depending on one’s position on Earth. (PS2.B)
They started the lesson by giving us an apple and a flat board. We were to prop up the board to make it into an inclined plane. Then we were challenged to move the apple without pulling it or pushing it with our hands. We were given a few more materials and here are some of the ideas.
