Unique set up allows for easy measurement of Daphnia heart rate!
Your students will learn how to measure blood pressure and measure the pulse rate under different conditions such as standing, reclining, immediately after rising to illustrate baroreceptor reflex, and during and immediately after exercise. They will then relate their own blood pressure and pulse rate results to an index of relative fitness. Using the water flea, Daphnia magna, your class will measure and compare its heart rate under various temperatures and other factors. The investigation's comprehensive background section includes extensive coverage of the anatomy of various circulatory systems and the physiology of blood flow. Note: Includes a redeemable coupon for requesting the prepaid perishable culture of Daphnia magna. Please allow 2 weeks for delivery. Note: A sphygmomanometer and stethoscope are required but not provided.
