CELL STRUCTURE & FUNCTION, CONTINUED
Cell Size and Diffusion— Laboratory Kits
When students cut open stained agar cells in this hands-on laboratory, they understand why cells can be so small. Student measurements and calculations clarify the surface area-to- volume ratio that is key to understanding cell size limitations. Includes detailed instructions and necessary chemicals and specialized equip- ment. Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs.

Introduction to Osmosis and Diffusion—Student Laboratory Kit
Bring passive cell transport to life by creating artificial cells with dialysis tubing and simulated cellular fluid of glucose
and a special dye. Dye diffusion is directly observed, mass and volume measurements prove osmosis of water takes place, and glucose test strips confirm molecules diffus- ing through the cell membrane pores.
FB1870 I $43.55
Membrane Diffusion—Student Laboratory Kit
A two-part experiment to solidify the concepts of osmosis, diffusion and semipermeable membranes. Students conduct trials with dialysis tubing then with plant tissue and compare and contrast the two systems to become familiar with concepts like hypotonic, isotonic and hypertonic and relate them to water balance in living organisms and evolution. Materials for 24 students work- ing in pairs.

In Use
Phospholipid and Membrane Transport Kit
Explore the structure of a phospholipid,
then construct a phospholipid monolayer. Features include the amphipathic structure of phospholipids with their hydrophilic heads and hydrophobic tails. Additional kit components allow students to construct lipid bilayers and consider how transport proteins move ions and small molecules across membranes.

Diffusion and Osmosis— Laboratory Kits
Students use semipermeable membranes to simulate the absorption of nutrient molecules into cells. Experiments use starch and glucose to demonstrate why some foods must be chemically broken down before being taken up by the small intestine. Graphically illus- trated results with unmistakable color changes are easy for 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.
