FB1870 - $42.50
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...
FB1906 - $24.35
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. Transferring...
FB1826 - $84.30
What is the difference between diffusion and osmosis? Students explore the processes of diffusion and osmosis using a selectively permeable membrane. Students investigate the relationship between solute size, solute concentration and the passage of...
FB1827 - $129.95
What is the difference between diffusion and osmosis? Students explore the processes of diffusion and osmosis using a selectively permeable membrane. Students investigate the relationship between solute size, solute concentration and the passage of...
FB1828 - $67.35
What is the difference between diffusion and osmosis? Students explore the processes of diffusion and osmosis using a selectively permeable membrane. Students investigate the relationship between solute size, solute concentration and the passage of...
FB0435 - $46.60
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 semipermeable...
FB1573 - $21.80
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. Randomly...
FB1638 - $44.35
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...
AP6019 - $49.80
Molecules diffuse through the semi-permeable membrane at the bottom of the double thistle tube. The thin column of the thistle tube magnifies the volume and color changes. The concept of osmosis will be clear to your students after they witness the...
AP8638 - $44.55
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...
FB0752 - $37.40
A two-part experiment to solidify the concepts of osmosis, diffusion, and semi-permeable membranes. Students will conduct trials first with dialysis tubing (an artificial membrane), and then with plant tissue (a natural membrane). They will compare...
FB2030 - $84.45
Big Idea 2, Investigation 4, Science Practices 2, 4, 5 How do cell membranes help regulate internal cellular makeup? In this Flinn Advanced Inquiry Lab, students participate in two Baseline Activities that branch out with Opportunities for Inquiry...
FB2052 - $75.80
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...
AP7568 - $96.70
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...
FB2086 - $68.15
This is the refill kit for the Diffusion and Osmosis Advanced Inquiry Laboratory Kit. See full kit at FB2030. Refill Kit includes: Agar  Albumin  Dextrose  Dialysis tubing  Hydrochloric acid solution, 0.1 M  Phenolphthalein,...
