Keith's class has been learning about the effects of Earth’s gravity. His teacher challenges his class to imagine that tunnels are dug into the earth. The teacher draws the diagram below and asks the students to think about what would happen if a red ball were released at the entrance of a tunnel. If a small ball, represented by the red dot in the image to the left, is held just above the tunnels, which path (path A, path B, path C, or path D) would it follow when released? Select the best claim Keith could make about the path the ball would take.

• The ball would follow path A because gravity would pull it to the center of the earth.

• The ball would follow path B because gravity would pull the ball down the tunnel at a slant.

• The ball would follow path C because it would be trapped in the earth’s orbit.

• The ball would follow path D because gravity is a force that pull objects down.

Describe a day in your classroom without gravity. What would the objects around the room do without gravity? How would things be different?

Write a scientific explanation about the direction of Earth’s gravitational force, using the evidence in the scenario.
