The Breathing Machine

In this video review about the human body learning exercise, students observe the Eyewitness video "The Human Machine" and fill in the blanks with comprehensive answers. Students write 23 answers. 

Take a deep breath and have your class construct working models of a lung! Using 500ml plastic bottles as the chest cavity, and balloons for the lung and the diaphragm, learners work in groups to make a model. The models help them to...

Learners create a model of the lungs and diaphragm. In this breathing lesson, students create a model out of a plastic bottle and balloons. They see how the diaphragm helps to fill the lungs with air. 

Learners discover their magnificent breathing machine. In this science lesson plan, students learn the functions of the lungs in our bodies and become aware that in breathing an exchange of gases takes place in the lungs.

Young scholars, in groups, compare heart and breathing rates at rest, during exercise, and after exercise.

Students study the respiratory system, the lungs and air.  In this respiratory lesson students describe technologies that engineers have found that improve the health of the respiratory system. 

Students study animals. In this machines and tools lesson, students study animals to figure out how various tools were created for humans to use. They are read the story An Elephant Never Forgets its Snorkel to help spark ideas. They...

Here is a well-designed science lesson that shows learners that everything that organisms do in ecosystems, including running, breathing, burrowing, growing, requires energy. After a thorough discussion of their own eating and drinking...

Students study the parts of the human respiratory system while examining the gas exchange that takes place in the lungs. They make a model lung. They look at how the respiratory system is affected by spaceflight.

Young scholars examine the inhalation and exhalation process. They create a model pair of lungs from given materials. They discover the technology that has been developed based on engineers examining the respiratory system.
