Designed for the new specification AQA GCSE course but can be modified for other exam boards.

16 slides covering Osmosis .

By the end of the powerpoint students would have covered:

Water may move across cell membranes via osmosis. Osmosis is the diffusion of water from a dilute solution to a concentrated solution through a partially permeable membrane.

Students should be able to:
use simple compound measures of rate of water uptake
use percentages
calculate percentage gain and loss of mass of plant tissue.

Required practical activity 3: investigate the effect of a range of concentrations of salt or sugar solutions on the mass of plant tissue.
