Lesson plan

Forces that act at a distance

Summary
Students try magnets at several stations to learn about their properties, including magnetic force acts at a distance. Then use a balloon to show electrostatic force also acts at a distance.
Science content
Physics: Motion and Forces, Newton’s Laws, Gravity (K, 2, 6)
Procedure

Run the magnet activities as the magnet stations lesson.
Along with other properties of magnets, conclude that magnetic force acts at a distance.
Discuss how gravity is also a force that acts at a distance.
Use balloon static to demonstrate electrostatic force, which also acts at a distance.

Notes

Add gravity activity
