Get an up-close look at energy transfer. Using a three-part activity, investigators first observe a teacher-led demonstration before building a model marble track to convert potential energy to kinetic energy. Scientists explore six other energy transformations at various stations in the second part of the investigative experience. To finish, they evaluate and revise their marble track models and participate in a group discussion about their encounters.

Instructional Ideas

• Provide access to a variety of graphic organizers for note taking
• Invite designers to demonstrate their marble tracks in a racing competition

Classroom Considerations

• Requires some materials not traditionally found in the learning space
• Check with school administrators before using an outside person for the ambassador role described in part two of the activity

Pros

• Includes ideas to extend the learning experience
• Variation of activities help hold student interest

Cons

• None
