Grade Level: 9th - 12th; Type: Life Science
Osmosis and diffusion are in some ways alike. This experiment will be covering diffusion. The sodium hydroxide will mix with the phenolphthalein agar cubes and diffuse into the cubes. You will be able to see how much diffusion had occurred and compare the ratios of surface areas to volumes. You will then conclude which is better for diffusion and cell absorbing, more surface area, or more volume.
