Semipermeable Membranes and Bioaccumulation
Beginning biologists place a drop of food coloring into water of differing temperatures to observe the effect on the diffusion rate. They remove the shells from raw eggs and then experiment with osmosis over the remaining membranes....
Concord Consortium
Diffusion Across Semipermeable Membranes
Mitochondria use two semipermeable membranes to work properly. Young scientists adjust the pore size for two membranes. They then observe the diffusion of two different sizes of molecules.
Concord Consortium
Diffusion Across a Semipermeable Membrane
Semipermeable membranes allow water to go through—but not larger molecules. The simulation encourages pupils to adjust the membrane pore size to understand how this works. It also provides a way to trace the movement of a single molecule.

Diffusion across a Selectively Permeable Membrane
Lab groups fill a section of dialysis tubing with glucose and starch solutions and suspend it in a water bath. They use iodine as a starch indicator and a glucose test strip to find out if either of the materials crossed the selectively...

Cellular Soap Opera - Soap Films Can Behave Like Membranes
Soap, suds, and cell membranes. Pupils create a model of a cell membrane by using soap films. They experiment with trying to pass different objects through the film without popping it. Using a tube, they create a passageway through the...
