Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the angle sunlight and the angle of their solar panels. This exercise is meant to prepare learners to participate in solar car races, but can also be used in a meteorology unit to explain why different parts of the planet are warmer: more sunlight, more heat.
