Introduce diffusion and osmosis to your class with our interactive model!
Diffusion and osmosis are fundamental concepts in biology. Give your students a new insight into them with our easy to make model. Your students start by making their models of cells and molecules.
They then look at how diffusion happens in a container and then across a cell membrane. Then they will look at osmosis across a selectively permeable (or partially permeable/semi-permeable) membrane into and out of a cell.
These activities will teach them about concentration gradients, permeable membranes, importance of molecule size, factors that affect rates of diffusion and more.
