Catalase Investigation with Purified Enzyme—Super Value Guided-Inquiry Kit
By: The Flinn Staff
Students design and conduct experiments to investigate enzyme reac- tion rate using purified catalase. In the introductory activity, students precisely control the concentration of catalase while varying the concen- tration of the substrate. After refining the floating disk assay protocol, students design experiments to test other variables. Connect this investi- gation to the importance of maintaining homeostasis for proper enzyme function and the role of enzymes in evolution.
Super Value Kit is complete for 5 classes of 30 students working in pairs.
Catalase Investigation using an O2 Gas Sensor—Super Value Guided-Inquiry Kit
By: The Flinn Staff
Students design and conduct experiments to investigate enzyme reaction rate using purified catalase and a Vernier O2 Gas Sensor. In the introduc- tory activity, students precisely control the concentration of catalase while varying the concentration of the substrate and determine the rate of reaction. Students then design their own experiments, discovering what makes enzymes function most efficiently. Connect this investigation to the importance of maintaining homeostasis for proper enzyme function and the role of enzymes in evolution.
Super Value Kit is complete for 5 classes of 30 students working in pairs. A Vernier interface and O2 Gas Sensor are required and avail­ able separately.
Digestive Enzymes—Laboratory Kit
By: The Flinn Staff
General, Organic and Biological Chemistry
Investigate the properties of digestive enzymes that break down plant and animal tissue—food—into glucose, amino acids and fatty acids needed for metabolism and growth. Students investigate the actions of amylase, pepsin and lipase on proteins, starches and fats. The results are used to determine the optimum pH conditions for specific enzymes.
Complete for 24 students working in pairs for Part A and groups of 4 in Part B.
Help from MOM—Biochemistry of
Antacids Demonstration Kit
By: The Flinn Staff
With a little help from MOM—milk of magnesia—and universal indi- cator, students will clearly see the neutralizing effect of magnesium hydroxide on stomach acid. Colorful demonstration is sure to provoke interesting discussions of other medications and the biochemistry of the human body. Includes detailed instructions, student worksheet, and enough materials to perform the demonstration seven times. Concepts: Acid–base neutralization, digestion, antacids.
Time Required: 15 minutes
Materials Provided: Milk of magnesia, hydrochloric acid, universal indicator solution, pipets.
