Food Analysis—Testing Some Common Foods—Student Laboratory Kit
Using the materials supplied in this five-part kit, students test food samples for starches, sugars, lipids (fats), proteins and vitamin
C. Students gain an understanding of the chemical makeup of substances in foods commonly found in the home. Try this food analysis kit—it is a great addition to your biochemistry curriculum! Complete for 100 tests and 12 groups of students.

Sam ̓n ̓ Ella ̓s Café—Simulated Food Poisoning Laboratory Kit
Initiate a lively discussion about the safe handling of food after students “eat” a buffet meal and participate in a true-to-life simulation. Once food has been selected
by each student, the “food” (water) on their plates (cups) is tested to determine who and how many are “sick.” Then students deter- mine which food is contaminated and which “bacterium” may have caused the illness. No living bacteria are used—testing the “food” for contaminants involves detecting the presence of a base using a pH color indicator.
Extraction and Isolation of Caffeine—Student Laboratory Kit
In this lab activity, students first perform separation methods by extracting and isolating caffeine from tea leaves. Next, they calculate percent recovery and analyze the recovered caffeine for purity using different methods, including thin-layer chromatography (TLC), crystallization and sublimination. Includes materials for 30 students working in pairs. A short- wave UV lamp is required.

Alcohol Fermentation— Demonstration Kit
In this demonstration, as fermentation occurs, the depletion of the oxygen in a flask causes a dramatic color change in the indicator in the flask. Simultaneously, the carbon dioxide produced from the reaction causes a color change in a different indi- cator solution in the collecting chamber. Enough indicator solutions, yeast and sugar are provided to conduct the demonstration seven times. Detailed instructions and back- ground information are provided.
