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
Chemistry experiment
Dissolving race
Compare how quickly the same amount of sugar dissolves under different conditions.
Investigation questionHow do temperature and stirring change dissolving time?

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.
Water temperature
40°C
Kept the same10 g sugar · 200 mL water
Run and observe
The model uses the settings shown above. Add several trials to compare results.
40°C↻ stirring
Safety and model note: A model using ordinary sugar and water. Never taste laboratory materials. Virtual results simplify real systems, so physical observations may vary.
