The Energy Behind Roller Coasters

Driving or Multi-dimensional Question:

How do roller coasters work, and how are forces and energy transfer involved?
Students will explore the science of roller coasters. How is the law of conservation of energy used for enjoyment in theme parks, while keeping the thrill seekers safe?

Unit Summary:

The concept of energy transfer in and out of systems can be predicted qualitatively and quantitatively. Students should be able to understand the conservation of energy, how energy is stored and transferred, the relationship between forces and how they are related to energy and how it is used in the making of rollercoasters. This lesson incorporates evaluations of energy transfers and conservation using online simulations. Then students will use what they have learned to build and test a prototype. Students will conduct investigations and analyze data to evaluate their model and compare it to those of their peers.

Hook Event:

Roller Coaster Ride – Watch the video of Dollywood’s Wild Eagle Ride

Beginning Questions:
What factors make a roller coaster ride so exciting?
Where does the energy for making the roller coaster “go” come from?

Culminating Event:

Students will design, build and test a roller coaster design of their choosing, factoring in safety of the riders (marbles, steel ball bearings, plastic balls). Students will decide the parameters to be tested through class consensus before testing begins. Students will test their own design and one other group’s from the class. Class data will be recorded and analyzed. Each group will design a multimedia presentation to share with the class, to include a brief discussion of a roller coaster engineering career.

Students will use class data and pictures of the models to make an argument supported with evidence on the best model roller coaster design. Students should include what they learned about the job of roller coaster engineering.
