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.
