Described are several laboratory investigations that may be used to introduce biochemistry. Topics covered include carbohydrates, lipids, proteins, and metabolism. Reactions, stock solution formulas, and procedures are listed. Emphasized are individualizing work, designing alternative investigations, solving problems, and drawing conclusions. (KR)

Examines the thermal decomposition of sodium bicarbonate to sodium carbonate. Encourages students to predict the end products and to use the stoichiometric results to determine if their predictions are correct. (MVL)

Provides two demonstrations: (1) electrolyte migration of ions using colored ions which cross a strip of gelatin allowing for noticeable migration; and (2) photochemical reduction of Fe+3 by the citrate ion. Points out both reactions can be done in a Petri dish using common lab materials. (MVL)

Explores the selection, source, funding, time constraints, and community support involved in developing carefully planned and executed science projects. Lists 21 kinetics experiments noting the instrumentation needed and the original references. (MVL)
