Learn STEM with simulations and virtual labs

Missions, measurements, and visual models for lessons in class and at home.

Open simulations Simulations

All Simulations

Compare R, RC, RL, and RLC circuits, phase shift, impedance, and resonance.

Build electron configurations and test orbital filling with quantum numbers.

Build isotopes, vary N/Z ratio, and test which nuclei remain stable.

Test buoyancy in liquids and predict when objects float, sink, or stay suspended.

Charge and discharge an RC circuit, then track capacitance, field, and time constant.

Place charges and explore field lines, vectors, and electric field strength.

Build Lewis structures, compare VSEPR shapes, and estimate molecular polarity.

Change concentration, volume, and temperature and predict shifts using Q and K.
