Plan your fair test
This is an assessed investigation. You will plan a fair test using a foil ribbon as a wire, get it approved, then run it.
1. My testable question:
2. My variables:
| Variable job | My plan |
|---|---|
| CHANGE | |
| MEASURE (and how) | |
| KEEP THE SAME (at least two) |
3. My prediction (what + why):
4. My method, with one safety note:
Record your results
Keep your results safe — you'll graph and evaluate them next lesson.
Once your plan is approved, build the circuit, change only your one variable, and record your results.
| Foil length (cm) | Brightness (0-3) |
|---|---|
| 10 cm | |
| 20 cm | |
| 30 cm | |
| 40 cm |
State your result in one sentence: "As the foil got ___, the globe got ___, which (did / did not) match my prediction."
