Diffusion, Osmosis and Active Transport
These resources can be used in the delivery of lessons on transport (diffusion, osmosis and active transport) at KS4. It is intended that the sequence of lessons would be as follows:
1. Diffusion (using either the "Diffusion experiment" or the practical guide to illustrate the process). The animation can also be shown a an explanation or a summary at the end of the lesson.
2. Osmosis (using the "Osmosis Activity"). The "Egg osmosis" experiment can also be set up at this point and left to run over the course of the next week. The animation can again be used to introduce or to summarise the process.
3. Active transport (if appropriate to the specification) (using the BBC Bitesize animation and some or all of the worksheet).
