Pumping Heart Chamber Fluid Dynamics STEM Lab (BIO02) | Biology

🫀 Pumping Heart Chamber Fluid Dynamics STEM Lab (BIO02) Explore circulatory system anatomy, cardiac pressure differentials, one-way valve mechanics, fluid flow rates, and stroke volume! The Pumping Heart Chamber Fluid Dynamics STEM Lab (BIO02) challenges middle school student teams to act as biomedical engineers, constructing a working mechanical heart model to investigate how pressure differentials and one-way valves circulate fluid. Students explore cardiac muscle contractions, atmospheric vs. chamber pressure, valve regurgitation prevention, stroke volume, and cardiac output math! 📦 What is Included in This 3-Page Packet: Page 1: Teacher Guide & Lesson Plan: NGSS alignment (MS-LS1-2, MS-LS1-3, MS-ETS1-2), target science concepts, and fluid station setup guide.
