Energy Transfer and Efficiency Challenge
Energy moves through every system — but not all of it does useful work. Where does the rest go?

Evidence you will build
- Multi-stage energy flow diagram
- Efficiency calculation table
- Redesign brief
- Before/after comparison dataset
Why this matters
Energy is never created or destroyed — only transferred. Communities redesign systems when efficiency data shows where energy is wasted.
What you will investigate and collect
You will track energy through a multi-stage setup, calculate efficiency, diagram the flows, and redesign one part with evidence. How energy transforms across stages and whether a targeted redesign improves overall efficiency. Joule or proxy measurements per stage, efficiency calculations, and before/after trial data for your redesign.
- Date and time
- Stage
- Energy in (J)
- Energy out (useful) (J)
What you might make or share

Isolate one fair-test comparison with a disposable small print
When one variable dominates your comparisons, printing a test shape keeps other factors steady.
