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?
1

Make a prediction

What do you think will happen with these settings? Explain why.

Your investigation is saved as you work.
2

Change the variables

Change one variable between trials when you want a fair comparison.

Light each day
8 hours
Water each week
100 mL
3

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.
