# If you need a natural stopping point!

Teachers: If you are short on time, this is a good stopping point. We recommend leaving your students' tracks set up so they can get right to experimenting at the start of the next session.

If you’re continuing right now, advance to the next slide.

THIS LESSON WAS REVISED ON JULY 1, 2019. Here is a link to the previous version.
In this lesson, students explore how energy can be stored as height. In the activity, Bumper Coasters (Part I), students build paper roller coasters. Students release marbles down the roller coaster track to understand height energy and energy transfer.
