Innovating Science™ Diffusion and Cell Size

Why are cells microscopic?

Supplier:  Innovating Science™ IS3003

Catalog No. S98650

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

Description

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

 

Compliance

Conforms to 49 CFR 173.4
