Learn STEM through interactive simulations and virtual labs

Learn STEM through interactive, multilingual simulations and virtual labs designed for classrooms and home learning.

All Simulations

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

Explore how filters work! Add activated carbon to polluted water and watch how its porous surface absorbs harmful molecules.

Follow oxidation alcohol → aldehyde → carboxylic acid and compare functional groups.

Find the domain, cancel factors, convert to a common denominator, and discard extraneous roots.

Build squares and rectangles to see why (a+b)², (a-b)², and a²-b² work.

Compare addition vs substitution and see why benzene prefers substitution.

Build a protein molecule! Connect amino acids with peptide bonds and observe the formation of a long polymer chain, the basis of all life.

Learn to measure the world in degrees! Estimate angles by eye, use a virtual protractor, and construct specific angles with high precision.
