Home Electricity Audit – Teacher Guide
Summary
This teacher guide lays out a complete, classroom-tested plan for running the Home Electricity Audit in 2–3 class periods—with clear pacing, checkpoints, and the most common “gotchas” flagged. Start with a sample utility bill to teach cost per kWh (supply vs. delivery), then send students to collect appliance data using labels or quick research. Back in class, students calculate kWh/day and cost/day, build a pie chart or bar graph, and reflect on why estimates and real bills don’t always match.
Built-in supports: teaching notes, reminders to prevent common calculation errors (including the lighting note), and an optional extension where students research a more efficient appliance and compute potential savings/payback. Wrap with a poster/infographic/mini-presentation if you want a communication product without adding complexity.
- Day 1: Read sample bill + practice kWh/cost math
- Day 2: Audit calculations + table completion
- Day 3 (optional): Graphing + efficiency upgrade + reflection/presentation
- Assessment: rubric included (quick-grade)
