Science of Energy Efficiency – Investigating Energy Efficiency Lab – Student

Summary

Students measure electrical energy input and thermal energy output from a heating device, calculate efficiency using real formulas, and compare results across groups to explore why no device reaches 100% efficient. The three-part procedure walks from data collection through calculation to analysis questions and a written conclusion. Pairs directly with the teacher guide and works in physics, earth science, or APES with access to a Kill-a-Watt meter and basic lab equipment.
