Flinn Molecular Model Sets
The colorful, sturdy plastic atoms and connectors in the Flinn Molecular Model Sets will endure years of molecular model building. The easy-to-assemble compo- nents can be used again and again for single-, double- and triple-bonded mole- cules. Models adapt to student group use or classroom demonstration and display. Instructions and plastic storage case or bag included with each set. Replacement atoms and bonds are available separately.
7 options available at flinnsci.com $17.80–$105.70
Balancing Equations—
Human Reflex Study—
Super Value Kit
Super Value Laboratory Kit
Use this hands-on kit to make the abstract concept of atoms become more visual
and real for students. Students count and manipulate the “atom” chips until all atoms in the equation are conserved and then write the final equation on the provided data sheets. All materials are reusable.
AP4577 I $39.65
Students perform five tests to observe the innate reflexes the body performs to main- tain homeostasis. Reflex tests include the patellar, Achilles, Babinski, pupillary and blink reflexes. Includes enough materials for 15 groups of students and five reflex hammers. All materials are completely reusable.
FB1988 I $40.40 From cells to tissues
to organs, visit flinnsci.com for more activities.
Aerobic Respiration and Fermentation Made Easy— Student Laboratory Kit
Students grow yeast cells in fermentation tubes and observe the metabolic byprod- ucts 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.
FB1750 I $55.60
Exercise, CO2 and Respiration—Student Laboratory Kit
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 production of CO2 and pH to regulate breathing. Includes materials for 30 students working in pairs. The Super Value Kit is available for 5 classes of 30 students working in pairs.
