Diffusion Demo

Mr. Anderson explains the diffusion process, highlighting the movement of molecules from high to low concentration. He describes the components involved in the diffusion and osmosis lab, including starch, glucose, water, dialysis tubing, and Lugol's solution. The video demonstrates a diffusion experiment using dialysis tubing, where starch and glucose are placed inside, and water and Lugol's solution are outside. Observations include color changes and glucose presence, illustrating diffusion principles. The goal is to rank the components by size using diffusion understanding.
