13 pages including a scripted lesson plan and interactive class experiments and demonstrations to teach students about diffusion and osmosis. They will learn new vocabulary such as concentration gradient, equilibrium, and semipermeable membrane. They will see that diffusion works through liquids and gases, the effect of temperature on diffusion, and investigate osmosis by studying the effects of both plain and salt water on potato slices. Welcome to the world of MatterMania! I hope you enjoy
