Innovating Science™ Diffusion and Cell Size
Why are cells microscopic?
Supplier: Innovating Science™ IS3003
Demonstrates the need for cells to effectively move materials in and remove waste.
- Create simulated cells (agar blocks) of different sizes
- Examine how effectively a substance is able to diffuse into the cell in a set period of time
- A special indicator in the cells will allow students to visualize the degree of diffusion
- The results will clearly display the fact that a smaller volume creates a more favorable condition for the exchange of material across cell membrane
Conforms to 49 CFR 173.4
