Description

Students will learn about some of the main variables that determine what can be powered by a solar panel. Solar panels can be hard to understand, as they appear to be powering things but it's not clear how and why they work. By gathering both quantitative and qualitative information, students will get a better idea of how solar panels work, where they work best, and what variables affect their productivity. Students will use a tool called a multimeter to read the exact voltage and amperage of a solar panel, which will help them measure, understand, and compare the information they gather during the hunt.
