Cell Diffusion Race Challenge – Design your own cell that will maximize mass and minimize diffusion time.

Learning Objectives: Calculate relationships between surface area and volume; determine how cell size and SA:V ratios affect diffusion; apply these mathematical relationships to living cells.

Key Concepts:  the cell (plasma membrane, cytoplasm, mitosis); acid-base indicators; diffusion (hypotonic and hypertonic solutions); metric measurements; calculating surface area, volume and ratios; graphing on Excel.
