A good question starts a great experiment.
Three focused investigations you can adapt to your class. Each includes a prediction, a method, a recording table and questions for discussion.
Where does a sharp image form?
A 25-minute lens investigation: vary object distance, focus the image and compare your measurements with the thin-lens model.
Open teaching guide 20 minutesElectricity · Investigation guideWhat changes when you add a resistor?
A 20-minute circuit investigation comparing series and parallel resistance, current and voltage.
Open teaching guide 25 minutesMotion · Investigation guideWhat sets a pendulum’s rhythm?
A 25-minute pendulum investigation exploring length, mass and the small-angle approximation.
Open teaching guideRead the model notes in each experiment before teaching. Adjust the level of mathematics and the amount of guidance to suit your learners.
The guides can be printed using your browser’s print command, or shared as links. Use the notebook to collect observations and download them before leaving the simulation.
These activities are not an exam-board endorsement or a substitute for checking your syllabus. They are designed to support questions, measurement and discussion.
Let curiosity take the controls.
Choose an experiment. Change something. See what happens.
