Lists materials and methods for an experiment that demonstrates the concept of glomerular filtration rate (GFR) using anesthesized dogs. In the dog, GFR is equivalent to the renal plasma clearance of exogenous creatinine. (CS)

Describes an experiment using rats that demonstrates contractile characteristics of normal and hypertrophied muscle. Compensatory hypertrophy of the plantaris muscle is induced by surgical removal of the synergistic gastrocnemium muscle. Includes methods for determination of contractile properties of normal and hypertrophied muscle and…

Described is a visual method for teaching the principles of titration. It has been used successfully with secondary school and college level students. (RH)

Experimental techniques are taught in a laboratory course designed with some student options available. Eight experiments which use vacuum systems, radiation sources, dispersion and detection systems are outlined. A course outline and time table are given. The final examination is described as 30 minutes of individual practical work and dialogue…

Describes an experiment that utilizes the techniques of temperature synthesis, crystallization from a molten salt, oxidation-reduction in a molten salt, powder X-ray diffraction and analysis by high temperature volatilization or a specific ion electrode. (MLH)
