Cells and Genetics—Diffusion and Osmosis
Introduction to Osmosis and
Diffusion—Student Laboratory Kit
By: The Flinn Staff
Bring passive cell transport to life in this student laboratory kit. Students create an artificial cell using dialysis tubing and simulated cellular fluid containing a special dye and glucose. The diffusion of dye through the membrane can be directly observed, but what about the water and glucose? Mass and volume measurements prove that osmosis takes place, while glucose test strips confirm that the unseen glucose molecules also diffuse though the pores in the artificial cell membrane. Kit includes reproducible student handouts, detailed background infor- mation, complete Instructor’s Notes with sample data and answers to all questions, and all chemicals and consumable supplies needed to perform the lab.
Complete for 30 students working in pairs.
Diffusion and Osmosis—
Student Laboratory Kit
By: The Flinn Staff
Students will gain experience and understanding using semi-permeable membranes to simulate the absorption of nutrient molecules into cells. Experiments are carried out using starch and glucose to further demon- strate why some of the foods we eat must be chemically broken down before they can be taken up by the small intestine. Results are graphi- cally illustrated by unmistakable color changes which are easy for your students to follow and identify.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
Cell Size and Diffusion—
Student Laboratory Kit
By: The Flinn Staff
Why are cells so small? Why aren’t cells larger? When your students cut open their stained agar cells and see the diffusion pattern for themselves, the answers will be obvious. Student measurements and calculations during this hands-on laboratory will dramatically clarify the concept of surface area to volume ratio. Instructor’s Notes, repro- ducible student handouts, and all necessary chemicals and specialized equipment are provided.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.
