Enzymes and Lactose Intolerance

Discover the science behind lactose intolerance! Students will learn about enzymes and model lactase, the enzyme responsible for breaking down the sugar lactose. Then they'll conduct tests to determine if over-the-counter LACTAID (R) can digest lactose. Finally, students will design and conduct a series of experiments to explore the impact of pH on the action of enzymes.

This kit will have students excited about scientific discovery. They'll learn key concepts including

1. Enzymes are biological catalysts
2. Reaction rates are impacted enzymes
3. Temperature and pH influence enzyme function

This kit can be conducted in the classroom or at home in two 40 minute sessions plus homework. Comes with complete Teacher Guide and Student materials.

• 5 Labeled droppers
• 1 LACTAID (R) capsule
