- Diffusion and Osmosis Kits
Cell Size and Diffusion - Student Laboratory Kit
FB1638
Why are cells so small? Why aren't cells larger? Wouldn't it be more efficient to have larger cells? When your students cut open their stained agar cells and see the diffusion pattern for themselves, the answers will be obvious. Student measurements ...
 
Cell Size and Diffusion - Super Value Laboratory Kit
FB2052

Diffusion Demonstration Model
FB1573
Students will love this functioning diffusion model. The semipermeable membrane in the center of the model allows the passage of “small” molecules while keeping the “large” molecules trapped on one side of the membrane. Random...
 
Concentrating on Equilibrium Demonstration Kit
FB1906
No more confusion about diffusion and equilibrium! In this interactive class demonstration, students discover that diffusion is due to molecules moving randomly about and that the “final” state of equilibrium is really a dynamic condition. Transferri...
 
Dialysis Fundamentals Experiment Kit
FB0435
Introduce the basic concepts of osmosis and diffusion with this involving laboratory activity. Using a colloidal solution of starch and sodium chloride students will: • Clearly observe the process of dialysis • Observe diffusion through a semipermeab...
 
Diffusion and Osmosis - Student Laboratory Kit
AP8638
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 demonstrate why some of the foods we eat must ...

Introduction to Osmosis and Diffusion: Student Laboratory Kit
FB1870
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...
