Our new physiology sensors are ideal for physiology investigations with your students. Our current selection of physiology sensors include the Blood Pressure Sensor, EKG Sensor, Hand Dynamometer, Hand-Grip Heart Rate Monitor, O2 Gas Sensor, Spirometer, and Surface Temperature Sensor. This package of sensors greatly expands your capabilities to non-invasively study the dynamics of several systems of the human body. All of these sensors connect easily to the Go! Link, LabPro, and CBL 2. (Note that the Blood Pressure Sensor requires a computer.)

What Can You Do with Our Physiology Sensors?
Listed below are several ways in which our expanded line of physiology sensors can be used in your classroom to study human physiology. Consider the possibilities!

• Investigate grip strength using the Hand Dynamometer. How do strength and endurance relate? Will squeezing a tennis ball as tightly as you can 50 times each evening for a month increase your strength, endurance, or both? At the beginning of the month, measure and record your basal grip strength and fatigue rate. At the end of the month, compare your readings with those taken earlier to see how the values compare.
• How much heat energy is released from the top of your head? Place the Surface Temperature Sensor at the site of your fonticulus anterior (your former soft spot), and measure your surface temperature. Compare this reading with others taken from the palm of your hand, the sole of your foot, the back of your neck, and the ambient air. Which site dissipates the most heat energy? What would account for this? As ambient temperature lowers, would the “hot spot” change?
• Does caffeine really affect one’s blood pressure? Enlist the Blood Pressure Sensor to allow your students to investigate this question.
• What is your tidal volume? How does your flow rate compare to other people your own age? Spirometry measures the volume of air inspired or expired as a function of time, and offers an index of one’s pulmonary health. The newly released Spirometer is the tool you need to evaluate lung function.
• Investigate EKG and/or EMG after mild exercise. Electrocardiograms and electromyograms are both possible when using the EKG Sensor. It offers fascinating insight into the working of electrical conduction in the heart or in specific muscular tracts. It allows students to move from mystery to functional understanding of an empirical phenomena we all share.
• Monitor the heart and how quickly a person’s heart rate returns to normal after exercise (recovery rate). This indicator of cardiac health is simple and accurate when monitored with the Hand-Grip Heart Rate Monitor.

To complete our physiology product line, we are pleased to announce our new Human Physiology with Vernier lab book. The Human Physiology with Vernier lab book will be available just in time for the new school year (Fall, 2005).
