Building Energy Transfer Systems
Submitted by: Robert S.
Recommended Grade Level(s):
Appropriate for: Grades 6–8
Time Requirements:
Prep Time: 45 minutes (one time)
Activity Time:
40 minutes
Teaching Topics & Concepts:
Types of Energy: electrical, mechanical, light, chemical, potential, & kinetic
National Science Standards Alignment
CMS-PS3-5: Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes,
energy is transferred to or from the object. (Energy and Matter)
Safety:
• Students should be forewarned that any lamp with an incandescent bulb will become hot.
• Batteries hooked up to itself (from one end to the other) with just a single wire will short circuit and become hot.
Materials:
• Size D battery (per group)
• 2 alligator clip wires (per group)
•
Small motor with toy fan blade on the end; small, inexpensive, & safe (per group)
• Hand-crank generator (per group)
• Solar panel; small & inexpensive (per group)
• Lamp with incandescent bulb (if sunlight is not available)
• Rubber bands
Background Information, Activity Setup:
Students will build 3 different energy systems as well as draw them out & label the types of energy changes. Each time the small,
toy fan will spin on the small motor. Power will come from the hand-crank generator, the D cell battery, as well as from the small
solar panel. Discussions will ensure regarding the types of energy as well as any indications of potential &/on kinetic energies.
