Innovating Science™ Diffusion and Cell Size

Includes

Materials for 15 groups of students, teacher's guide, student study guide copymasters

Why are cells microscopic?

Demonstrates the need for cells to effectively move materials in and remove waste.

Students will:

• 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
