Students build a working model wind farm using small DC motors as generators, plastic or cardboard blades, and a fan as the wind source, then use a digital multimeter to record voltage and current across multiple test runs. The data table on the wind farm model lab sheet captures fan speed setting, number of turbines, volts, amps, and calculated watts, giving grades 5 to 8 homeschoolers a genuine introduction to electrical measurement and the power formula P equals V times I.

Five analysis questions push the experiment beyond data collection, asking your student to explain how turbine count and fan speed affected output and to consider real-world wind farm design challenges. Whether this sits inside a renewable energy unit study or as a standalone applied-physics lab, completing it demonstrates that your homeschooler can design a controlled test, manipulate a single variable, and draw evidence-based conclusions from quantitative data.
