Diffusion, Osmosis & Active Transport Simulation
Students build concentration gradients across a dynamic cell membrane, add transport proteins and observe net movement under simple diffusion, facilitated diffusion, osmosis, active transport and coupled transport. Seeing particles move helps students distinguish passive processes from those that need energy. The full interactive is available to licensed Education Universe users.
Years 10–12Explorer
Learning outcomes
- Explain diffusion and osmosis in terms of concentration gradients.
- Distinguish passive transport from active transport.
- Describe the role of transport proteins in the membrane.
Teaching guidance
Ask students to predict the direction of net movement before each change and to state whether the process needs energy.
