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.

What is diffusion and how does it occur?

Rank the following substances from smallest to largest: starch, glucose, water, pores in dialysis tubing, and IKI.

Describe the structure and composition of glucose.

Explain the role of dialysis tubing in the diffusion experiment.

What is the significance of Lugol's solution in the context of starch?

How can glucose test strips be used to monitor glucose levels?

What changes occur in the dialysis bag and surrounding solution after the diffusion experiment?
