This EDITABLE lab helps students visualize the selective permeability of cell membranes. Students will determine what substances can cross a membrane, using a simple setup. This can be a tricky topic for students and this lab and questions help students determine what factors affect which substances can cross. I have included an answer key and teacher setup notes for an easy experience.

Materials:

• Dialysis Tubing
• Powdered Glucose
• Powdered Starch
• Water
• Iodine
• Glucose Strips
• Beakers
• Rubber Bands

I have uploaded this in both a Word document and a PDF so that you can feel free to modify and differentiate to meet your students' needs. Enjoy!
