SciFunLab turns equations into experiments. Compare a projectile motion simulation with the forces behind the Magnus effect, then investigate viscosity inside the fluid dynamics lab. Each page opens the working model directly, with no synthetic worksheet or course page between you and the experiment.
Advanced learners can trace light in the ray tracing lab, inspect atomic signals with NMR spectroscopy, model populations in the ecology simulation, or practise network design with the subnetting simulator.
