This project investigates the role of the lactase enzyme in digesting lactose. By testing different food samples, students can analyze how effective lactase is for lactose-intolerant individuals. It's a hands-on approach to understanding digestive enzymes!
If lactase is added to lactose-containing foods, then the digestion of lactose will increase, demonstrating its effectiveness for lactose-intolerant individuals.

Label each test tube with the food sample names.
Measure 100 ml of milk and pour it into the first test tube.
Add a lactase tablet to the milk test tube and stir.
Repeat the process for each food sample.
Allow the mixtures to sit for 30 minutes.
Use the glucose test strips to test each mixture.
Record the glucose levels for each sample.
Analyze the results to see which food had the most glucose.
Draw conclusions based on the presence of glucose.
Create a graph to illustrate the results.
The test should show higher glucose levels in the milk treated with lactase compared to untreated milk. This indicates that lactase aids in lactose digestion, particularly for lactose-intolerant individuals.
