Moments of Inspiration 3

I remember Mrs Singleton, my high school biology teacher help us with understanding diffusion.

At the start of class she dropped a potassium permanganate pellet in a beaker of water and explained diffusion using the beaker of particles moving from a high concentration (the pellet) to a low concentration (the rest of the beaker).

By showing us an actual example and witnessing it happen in front of us helped us to understand what exactly was meant.

So even though its such a simple visualization it really helps in the long run.
