 This activity is used to simulate some of the physics of a roller coaster.

Key Concepts: Energy and momentum

Student Involvement:  Several groups of students will help make a roller coaster track with a plastic tube that will allow a gum ball to roll from the beginning to the end.

Engineering Roles: Mechanical, civil, and industrial engineers

Real World Connections:  Engineers design roller coasters so that the energy of the roller coaster coming down from a high point can be used to make the coaster go through loops and up smaller hills.

Materials: 1 6ft plastic tube and several gumballs

Setup: The students will make loops with the plastic tube and place a gumball in it to see if it makes it through the track.

Suggestions: Do not let students swing the tube, and changing the elevation can increase the momentum
