Below is a listing of classroom protocols available on the Web. Some are simply links to the authors web page describing the exercise and others are links to web pages I have created based on scanned exercises submitted to me. In either case, the person to contact concerning questions about the protocol is the author, not me (unless I am the author). If you would like to submit a protocol please refer to the submissions web page.

Grazing The objective of this exercise is to determine whether Paramecium behaves as an ideal filter feeder by observing the feeding rate as a function of prey concentration over the course of time.

Osmoregulation The objective of this experiment is to determine the rate of water efflux under different external solute concentrations, and then to use this information to determine whether osmoregulation is occurring. Students will also determine the two key parameters required for analysis of osmoregulation, a) the iso-osmotic concentration of sucrose for Paramecium and b) the specific permeability of the membrane for water.

Food vacuoles The objective of this lab exercise is to determine the kinetics of food vacuole turnover in well fed cells and to analyse this process through examination of conceptual models. We will use water color suspensions to label food vacuoles. By use of two different colors we can distinguish between food vacuoles formed after addition of the second color (black) and those formed earlier (red).
