Virtual science experiments
Investigate one variable at a time in safe, repeatable simulations. Record several trials and look for evidence of a pattern.
5 guided simulations
Light experiment
Shadow explorer
Move a virtual light source and measure the shadow made by an object.
Investigation questionHow does the angle of light change a shadow?
Make a prediction
What do you think will happen with these settings? Explain why.
Your investigation is saved as you work.Change the variables
Change one variable between trials when you want a fair comparison.
Light angle
35°
Object height
20 cm
Run and observe
The model uses the settings shown above. Add several trials to compare results.
☀35° light angle
Safety and model note: Use lamps rather than direct sunlight when testing shadows indoors; lamps can become hot. Virtual results simplify real systems, so physical observations may vary.
