What is the relationship among the heart, circulation, and exercise? Your class members will explore first-hand how different physical exercises affect an individual's heart rate. They will begin by learning how to measure their own...

Students work in groups to predict which condition produces more breaths per minute. Groups record their breathing rates during rest periods and periods of activity. They graph their results and make comparisons to their predictions.

Students gain an understanding of the respiratory system. In this biology lesson plan, students demonstrate how air enters and leaves the lungs, and explore the relationship between breathing rate and exercise.

What happens in the muscles during anaerobic and aerobic exercise, and how does this affect the heart and our overall health? A cross-curricular instructional activity that introduces learners to the lifelong benefits of exercise,...

Students observe and record how breathing changes with physical activities.  In this physical activity lesson students form groups and complete their activity and worksheets.

Middle schoolers determine their respiratory rate and explore the factors that affect breathing rate.

Students fill out an anonymous questionaire to explore whether they might have asthma. They then set up a spreadsheet to enter the data, decide on a definition of asthma, and figure out the prevalence of asthma. Pupils simulate what it...

Students Explain how an increased level of activity translates to cells needing more oxygen and how the lungs supply this oxygen by entering the blood stream. They also can explain that the heart is responsible for moving both oxygenated...

The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...

Third graders examine and identify the effects smoking has on the lungs. They view and discuss pictures of a smoker's lung and a healthy lung, and read and discuss an informational handout. Students then participate in an aerobic...

Pupils read information about the internal organs and body systems. In this organs and systems activity, students read descriptions of the heart, lungs, stomach, small and large intestine, and liver and gall bladder. Pupils study images...

Learners determine the amount of air they use during rest and activity. They conduct experiments to calculate the number of breaths needed to empty a jug of water by exhaling through a tube into the container. Then, they figure how much...

Students explore a study of African women who are able to carry heavy loads by altering their gait; they then conduct experiments that study the relationship between exertion, weight and heart rate.

Students examine the effects of radon on their breathing. They review the anatomy of the respiratory system before completeing this lesson plan. They also complete equations to show how carbon dioxide forms in their body.

Students explore space science by completing a worksheet in class. In this astronomy lesson, students discuss and identify star patterns in the night sky and relate these patterns to the approximate time they appear. Students complete an...

Students use the body as a sensory laboratory to explore their five senses, heartbeat, bones, and even size. In this early childhood science lesson, students build science and critical thinking skills as they take part in up to 6...

Students examine the role of human respiration and how it relates to radon. They identify damage to the lung from the exchange of carbon dioxide and oxygen. They work together to complete a lab activity and worksheet.

A project that requires you to play with a dog cannot be all that bad, right? This scientific experiment entails the respiratory functions of dogs. Learn the chemical and bodily processes going on within your canine companions...
