Description

This cell size lab demonstration makes a perfect introduction to a cell cycle or mitosis unit. By showing students how diffusion is affected by cell size, the need for cell division is better understood.

Please note: This activity is also part of my Biology Unit 5: Cell Cycle and the Full-Year Biology Curriculum.

Included in this resource:

• A teacher instruction page with materials list and differentiation tips
• Pre-lab questions
• 2 pages of student instructions and step-by-step calculations
• Discussion questions
• Answer key

*This lab is written in demonstration format to avoid students using knives and bleach. It can also be completed as a lab experiment, if you prefer.

Topics include:

surface area to volume ratio (and calculations), diffusion, cell size, cell division
