What was happening?  Remember that particles in a liquid and gas can move around.

What was happening?  Remember that particles in a liquid and gas can move around.  We call the movement of one substance through a liquid or gas diffusion.

Diffusion Diffusion is the spreading out of a substance within a liquid or gas. It doesn’t require stirring!

Over to you… 1. Complete the worksheet 2. Describe where diffusion happens in humans? 3. Describe where diffusion happens in plants? Extension Describe and explain how diffusion can be sped up

WHY DO GASES DIFFUSE? Gas particles move from an area where there is a HIGH level to an area where there is a low LEVEL of the particles i.e. DIFFUSION.
