Solar Car Series: during What Part of the Day Can the Most Sun Power Be Collected?

In preparation for solar car races, middle schoolers attempt to discover what time of day the most solar energy can be collected. Begin by demonstrating the use of a voltmeter for measuring solar cell output. Take them outdoors to take measurements and make observations at different times of the day over a three-day period of time. Afterwards, critical -hinking questions on a worksheet help them assess their data.
