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
Biology experiment
Build the best greenhouse
Change two growing conditions and compare the predicted health of a seedling.
Investigation questionHow do light and water affect plant growth?
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 each day
8 hours
Water each week
100 mL
Run and observe
The model uses the settings shown above. Add several trials to compare results.
☀
8 h light · 100 mL water
Safety and model note: A simulation only. Real plant growth takes time and varies between species. Virtual results simplify real systems, so physical observations may vary.
