Welcome to AIDE Biology Lab area:

You must first complete the Lab Safety investigation. Then you must complete 9 additional investigations for the course credit. Each lab has a few questions to answer after completing the procedure for the lab. We currently offer 14 labs that are found in your text book. It is also an option for you to develop your own investigation. Your investigation must be associated with the materials in the chapter and MUST BE APPROVED BY YOUR INSTRUCTOR PRIOR TO YOUR INVESTIGATION.

Background Informantion: Diffusion is a process that involves movement of molecules, including solutes and solvents, into and out of cells. Solutes and solvents move by “diffusing” across cell membranes. Diffusion is an active process in which solutes and solvents, like water,move from an area of higher concentration to an area of lower concentration. In this activity, changes in a carrot will be used to depict the movement of water by diffusion.
