Have a HeartAdd to list Details
Your heart pumps blood throughout your body in one direction, around in a loop. In this activity, learners will make a model of one type of heart chamber called a ventricle.
Luminol TestAdd to list Details
Learners mix a solution containing luminol and copper with a fake blood solution. A chemical reaction between the luminol solution and fake blood (hydrogen peroxide) show learners a blue glow.
Seeing Your Retina
In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.
Listen to THIS!
In this activity, learners use plastic tubing and a funnel to listen to their heart. Learners also discover that if they run around, their heart pumps harder and faster, making it easier to hear.
The Pulse is Right
In this online activity, learners measure their pulse rates and investigate how their pulses change when they engage in different activities.
Heart and Lungs
In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.
Valves and Pumps: A Demonstration
This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.
Examining the HeartAdd to list Details
In this activity about the heart (on page 22 of the PDF), learners examine sheep or chicken hearts to learn about the heart's structure and the flow of blood through the heart.
Digestive System: A Kinesthetic Lesson
In this simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.
What's Your Blood Type?Add to list Details
In this activity, learners perform a simulated blood test procedure.
What Goes Around Comes Around
In this simulation activity, learners act as parts of the circulatory system and discover how it serves as a transport system for food/nutrients, oxygen, carbon dioxide and waste.
How Long Can You Hold Your Breath?
In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.
Changing Body Positions: How Does the Circulatory System Adjust?Add to list Details
In this activity about how the body regulates blood pressure (page 117 of the PDF), learners make and compare measurements of heart rate and blood pressure from three body positions: sitting, standing
Raising the Level of Carbon Dioxide in Your BloodAdd to list Details
In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.
Measuring Blood Pressure in SpaceAdd to list Details
In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.
In this activity, learners discover how their heart rate changes in different situations.
Drinking Straw Pulse Measurer
In this health activity, learners create a device so that they not only feel their heartbeat, but also see it, using a straw and some clay.
Heart to Heart
In this activity, learners compare ways to measure their heart rates. Learners build their own stethoscopes and learn how exercise affects heart rate.
Make a Heart ValveAdd to list Details
In this activity, learners make a model of a one-way heart valve to investigate how a heart controls the direction of blood flow.
What's in Your Blood?Add to list Details
Doctors often send a sample of blood to a lab, to make sure their patients are healthy.
