Theme Park Science with Jell-O Loop-De-Loops

Before You Start

 

ACTIVE TIME:
45 minutes-1 hour

TOTAL PROJECT TIME:
1-2 days

KEY CONCEPTS:
physics, forces, motion, centripetal force, circular motion

Introduction

 

Have you ever wondered what keeps you in your seat when you are riding a giant loop-de-loop roller coaster? Surprisingly, it is not the seat belt! You are kept in your seat because of something called centripetal force. Centripetal force actually does much more than make a ride on a roller coaster’s loop possible — it keeps a satellite in orbit and you in your bicycle when taking a tight curve! In this science activity, you will use marbles and Jell-O® to investigate centripetal force and circular motion. Which way will the marbles go?
