Solar Mobile

Solar Mobile Design Challenge Unit Plan

Grades:
6-8
Learning Goal(s):
Students will design circuits using various solar panels in order to power motors with propellers. Students will learn about solar energy transfer in order to power the motors on their solar aircraft.Students will research an aircraft and draw an outline of the aircraft onto foam board. Students will explore the concept of center of gravity. Students will test the efficiency of various light sources (incandescent, fluorescent, LED, halogen) for usage by a PV cell.Students will use their prior testing results and knowledge to engineer a solar-powered mobile. Students will work to transfer the most energy from the solar panels considering all the tested variables in order to power the fastest, most efficient mobile.Students will demonstrate and explain why their solar mobile should be chosen for the solar mobile display in the children’s museum.
