This diffusion simulation shows how some large particles dissolve and eventually spread out due to collisions between themselves and the surrounding smaller particles.

A simulation that demonstrates the mechanism of osmosis. Start the simulation and watch the particles randomly bounce around the screen. Notice that the sugar molecules cannot pass through the membrane but the water molecules can. Soon a state of equilibrium will be reached.

A simulation that demonstrates the mechanism of active transport. If a sugar molecule hits a carrier protein it will be transported to the other side of the membrane (against the concentration gradient).

This simulation shows the random movement of large smoke particles as they are being bombarded by the fast moving molecules that make up the surrounding air.
