Middle School Lung Physics & Biology Lab: 3-page STEM packet on respiratory anatomy, thoracic pressure differentials, Boyle’s Law, & expansion ratios.

Explore respiratory system anatomy, thoracic volume changes, diaphragm muscle mechanics, air pressure differentials, and Boyle’s Law! The Mechanical Lung Air Pressure Simulator STEM Lab (BIO03) challenges middle school student teams to act as pulmonary engineers, building a functional dual-lung chest cavity model to investigate how pressure changes drive inhalation and exhalation.

Students explore thoracic cavity volume, atmospheric vs. internal chest pressure, diaphragm contraction, lung collapse mechanics, and volume expansion ratios!
