Innovating Science™ Small Group Learning: Diffusion and Cell Size
This Small Group Learning: Diffusion and Cell Size kit allows students to create simulated cells (agar blocks) of different sizes and examine how effectively a substance is able to diffuse into the cell in a set period of time.
Supplier: Innovating Science™ IS3003SGL
- Why are cells microscopic? The answer relates to the need for the cell to effectively bring materials in and remove waste.
- In this activity, students will create simulated cells (agar blocks) of different sizes and 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 a cell membrane.
- Kit contains enough materials for 5 groups of students.
- Teacher's Manual and Student Study Guide copymasters are included.
