01At constant voltage, what happens when resistance doubles?
02Which condition is needed for continuous current?
03Which measurement uses amperes?

Pilot reports use grouped scores. Public impact results are hidden until at least five paired learner records exist.

Scientific model: The simulation uses Ohm’s law, I = V ÷ R, for a simplified direct-current circuit. Real bulbs can change resistance as they heat.

Use the simulation as evidence, not as the answer.

  1. Ask every learner to predict before touching a control.
  2. Change only one variable in each recorded trial.
  3. Compare series and parallel circuits in the next lesson.
  4. Assess a labelled circuit sketch, data table and CER response.

Help the learner think without doing the thinking for them.

Ask: “What stayed the same?”, “What evidence can you measure?” and “Would your explanation work for a different battery?”

Younger learners should handle the physical activity only with an adult or teacher present.
