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 jobMy 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."
