Move beyond assembling a solar model to investigating how its performance changes.

Your mission

Test a solar-powered fan under different conditions, record what happens, and recommend a setup based on your evidence. Practice predicting, observing, comparing results, and changing one variable at a time.

Before you begin

Complete Solar Fan DIY STEM or bring equivalent assembly experience. Gather the selected solar fan kit, a recording sheet, and a suitable testing location. Keep fingers, hair, and loose objects away from moving blades.

First challenge

Predict how changing the panel angle will affect the fan, then explain your prediction.
