Students investigate diffusion using different solutions of chemicals placed in agar dishes. In this diffusion lesson plan, students observe 3 demonstrations of diffusion using perfume, food coloring in water and sugar cubes in water. They discuss the movement of molecules and the reason for the movement. Students then observe the movement of 4 different chemical solutions through agar dishes. They compare the rates of movement by calculating the distance divided by the time.
