Put the spheres back in the bag. Discuss with your group why you think that much of the sphere was lighted by the flashlight. Write one sentence explaining this to your classmates. After completing the investigation have students sit where they are with their group. Have a discussion about how much of the sphere was lit by the flashlight.
Record responses on the board.
Question students about why they think this occurred. Reinforce the difference between a sphere and a circle. Distribute a globe to each group and have them try the same flashlight activity. Move all the students to a circle in the back of the room. Note that it shines in all directions, unlike the flashlight which shines in only one direction.
