Features 13 core lab activities coverign the fundamental concepts of physiology, ecology, plant systems and more
Use an absolute pressure sensor to measure the change in air pressure within a model “chest cavity” while causing the syringe "diaphragm" to change its volume.
Students investigate how air pressure and changes in air pressure allow us to breathe.
By measuring changes in air pressure in a model human lung, students learn about the mechanics of breathing while they:
Realize that substances have characteristic properties and that the air around us exerts pressure on everything (air pressure)
Realize that unbalanced forces will cause changes in the direction of an object’s motion
Demonstrate the complementary nature of structure and function in the lungs
Students gain experience conducting the following procedures:
This experiment may require software and an interface for data collection.
