Lung Model—
Student Laboratory Kit
Students can construct their own working lung models to demonstrate how differ- ential air pressure causes inspiration and expiration of air from the lungs. Plastic cups, rubber stoppers and balloons simulate body parts in this nearly indestructible model.
FB1442 I $39.75
Breathing Fitness Lab
Through various activities, students exper- iment with breathing rates, breath and lung volume, breath control and the CO2 in exhaled air. Students understand how breathing and respiration relate to fitness and exercise, how measured parameters correlate with height and weight and the consequences of lung damage.

Functioning Lung Model— Demonstration Kit
Extra large with clear plastic housing, this functioning lung model is visible from the back of the classroom. Rubber stoppers on the ends of the bronchus make replac- ing worn out lungs easier than traditional models that use string or rubber bands. Handle on the durable, latex diaphragm allows for easier expansion of the balloon lungs during operation.

Exercise, CO2 and Respiration— Laboratory Kits
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 regu- late breathing. Includes materials for 30 students working in pairs. Super Value Kit is available for 5 classes of 30 students working in pairs.
