## Simple Solar Tracker

Students observe and replicate a simple solar tracker. Students will learn basic electric circuits and terminology. Students will reflect on possible improvements for solar tracker. Students will reflect on how the engineering design process is used daily.

Students will be shown a working example of a solar tracker and asked to replicate the design based on their observations. The design incorporates four solar cells arranged in two arrays with each array reverse biased such that they generate a voltage that opposes the other. Whichever array receives the most light will generate more voltage... View full description >>
