Lactose Intolerance—Demonstration Kit
Intestinal gas is a problem for people who lack enzymes to digest certain foods. This demon- stration kit shows an over-the-counter enzyme LactaidTM (lactase) in action! Using flasks of various sugar combinations with and without Lactaid are compared for yeast cell gas production. Inflated and non-inflated balloons dramatically illustrate the concept and consequences.

Enzyme Optimization—pH and Temperature Guided- Inquiry Kit
In this inquiry-based lab, students analyze background information, develop a hypothesis and design and carry out an experiment to determine the optimum pH or temperature for four digestive enzymes and the buffers and test- ing solutions to test the progress or products of their digestion reac- tions. Cooperative class discussions help students draw conclusions about enzymes and how they work. Complete for 24 students working in groups of 4.
