Diffusion and Cell Size Lab
Observe the different rates of diffusion that occur among different sized cells.
Grade Level: Grades 9 - 10
Standards: NGSS-HS-LS1- 2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
Are you looking to illustrate the interactive systems within multicellular organisms? Look no further. Teach your students that different cell sizes lead to different rates of diffusion with this easy activity.

Cell size is determined by how easily a cell can get nutrients and excrete its wastes. Using agar cubes as a model for a cell, students will determine the best cell size to allow waste elimination and nutrient acquisition.
