Learning Goal(s):
Students brainstorm ideas and share with their group.Students draw and label Solar Mobile designs in Engineering Notebooks. Students research an aircraft to trace (if this was not accomplished in the Center of Gravity lesson) and trace the aircraft outline onto foam board. Students construct a solar circuit to power motors and propellers on a foam board aircraft and test multiple times before adding to the solar mobile stand. Students construct solar mobile stand and add their aircraft to a dowel attached to the central hub. Students work with a partner to balance each aircraft onto the mobile. Students test the mobile speed outside (depending on weather) and compare to speed under indoor light stands. After initial testing, students redesign circuits or mobile construction to optimize design. Students use hand-held devices to film their moving Mobiles to judge the machine’s speed. Students demonstrate how their Solar Mobile works and justify in writing why their mobile should be chosen for the Children’s Technology Museum.

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.
