Enzyme Catalysis Model—Super Value Laboratory Kit
Students use this teacher-developed set
to design and build working models of a functioning enzyme/substrate model from flexible polyehtylene foam. Materials are easy to cut and modify to show the active site and major concepts of competitive and noncompetitive enzyme inhibition. Building the models provides a hands-on way to teach abstract concepts. A Super Value Kit is also available for 30 students working in pairs. All materials are reusable.
FB1576 I $35.05
Exercise, CO2 and Respiration
How and why do athletes train to increase their breathing efficiency? Students will answer this question and explore the complex biofeedback mechanism by which the body uses the produc- tion of CO2 and pH to regulate breathing. Includes materials for 30 students working in pairs. Super Value Kit is available for 5 classes of 30 students working in pairs.
Mitochondria in Action— Student Laboratory Kit
Illuminate the “powerhouses” of the cell
by observing live, functioning mitochondria under the microscope. Using the specialized stain in this kit, students can vividly see mitochondria breaking down sugar. Color change is easily viewed as mitochondria oxidixe the dye-sugar mixture. Process
can be repeat several times with more dye solution. Enough materials for 30 students working in pairs. Fresh celery is required.
FB1823 I $30.95
Aerobic Respiration and Fermentation Made Easy—Student Laboratory Kit
Students grow yeast cells in fermentation tubes and observe the metabolic byproducts formed. Use glucose test strips to measure glucose concentration as it is consumed and an indicator to detect changes in oxygen concentration. Students graph data to compare the rates of glucose consumption and carbon dioxide formation as the yeast culture grows.

Sodium Alginate Respiration—Student Laboratory Kit
Quantify the rate of respiration with spherification, trapping a liquid inside a gelat- inous sphere. Students are completely engaged as they see their own slurry of algae coalesce into perfect gas-permeable spheres then expose them to different conditions and measure changes in gas concentration and pH and the productivity of the algae inside. Complete for 30 student working in pairs.
