Explore Gravity with Marble Runs
Season 2 Episode 51 | 1m 25s
Bring the excitement of an amusement park into your home by building a marble roller coaster. The motion of marbles as they roll down ramps is a great way to learn about the pushes and pulls that cause objects to move. In this activity, you’ll create different tracks for a marble as you and your child experiment with the forces of friction and gravity!
