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...

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...

Young scholars practice deep breathing exercises and write about a stressful time in their life and their reaction to it.

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 calculate their heart rate before and after exercise. In this health lesson, students find their resting heart rate and then exercise for 5-10 minutes. Students take their heart rate afterwards and observe the differences.

Students explore oxygen properties by conducting a cell experiment in class. In this respiration lesson, students discuss the process of breathing and how oxygen is inhaled before carbon dioxide is exhaled. Students utilize yeast, water,...

Students see how smoking tobacco affects physical activity. They perform an aerobic activity while breathing through a straw. This simulates how a smoker feels when exercising.

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.

Learners discover the benefits of a healthy heart through exercise.  In this physical education lesson, students participate in a few physical activities in order to get their hearts beating faster.  Learners examine a visual...

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

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.

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...

Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.

Why is breathing so difficult for asthma sufferers? To find out, learners build their own lung models in the investigation (from a British website, hence the term ventilation system instead of respiratory system). Using...

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...

The student will calculate the vital capacity of the air in the lungs and trace the pathway of air into and out of the lungs. They describe the pressure changes that occur within the chest cavity when you breathe. They compare air that...

Students explore homeostasis and identify it in work in an organism. They brainstorm things that stay the same and participate in several demonstrations that illustrate homeostasis. Students predict baseline breathing and jumping jacks

Young scholars practice raising their heart rates through exercise.  In this physical education instructional activity, students discover the key to a healthy body is a healthy heart that must be exercised often.  Young...

Fifth graders identify and describe the functions of the major body systems. They discover how to maintain a healthy lifestyle with proper nutrition and exercise. They answer comprehension questions to end the instructional activity.

Students investigate the behavior of isopods. In this isopod lesson plan, students make observations of an isopod and sketch the pillbug. They study the orientation of the isopods in relation to moisture in a chamber they construct from...

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Young scholars experience what it feels like to strain for air in order to empathize with people who have asthma. They create a simple model of the respiratory system to measure the effect of narrowed airway channels.

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 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...
