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
Electricity experiment
Light a virtual circuit
Build a low-voltage model using batteries, bulbs, and series or parallel branches.
Investigation questionHow do batteries and bulb arrangements change brightness?
