Why Cells Aren’t Big


A quick, easy & safe demonstration of cell size & diffusion. Explore the limits of cell growth!

Students construct and analyze simulated cell models of various sizes using a specially formulated agar to learn how cells obtain nutrients and excrete waste. They then use data, obtained by measuring the cell’s volume and calculating its surface areas, to form conclusions about the size limitations imposed by diffusion.

Key Scientific Concepts: Cell theory - Cell reproduction - Cell size limitations - Cell cycle. Cross-Curriculum Integration: Math - Chemistry.

Lab Kit for 40 students.
