Osmosis and diffusion - learning mat

This learning mat allows year 10/11 students to work through at their own pace, includes short activities and exam questions allowing you to facilitate that learning. Leveled activities allow students to meet the following criteria (taken from OCR GCSE science specification):
Foundation:
Recall that substances move in and out of cells by diffusion through the cell membrane.
Describe diffusion as the movement of a substance from a region of high to low concentration.
Understand the movement of oxygen, carbon dioxide and water in terms of osmosis and diffusion
Describe osmosis and diffusion in relation to plants
Standard:
Describe osmosis and diffusion in terms of the ‘net movement of particles’ and explain how they move.
Predict the direction of water movement in osmosis.
Explain how plants are supported by the turgor pressure within cells
Describe the effects of the uptake and loss of water on animal cells.
Higher:
Explain how w can increase the rate of diffusion
Predict the direction of water movement in osmosis
Use the terms: crenation and lysis
