A thorough investigation of cell transport is provided when completing the assignment. The first half requires biology class members to answer questions about diffusion and osmosis with the aid of diagrams. Then they fashion an...

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...

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....

A lab activity where students learn the concept of osmosis by observing an egg in different solutions. Included is a procedure for students to follow.

Brief text summary of what students learn in the Diffusion across a Selectively Permeable Membrane lab, along with links to download Student Handouts and Teacher Preparation Notes in PDF or Word formats. Main teaching points include...
