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.

  • 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.
