Pumping Heart Chamber Fluid Dynamics STEM Lab (BIO02)

Bring circulatory system anatomy, cardiac fluid pressure, one-way valve mechanics, and cardiac output math to life with the Pumping Heart Chamber Fluid Dynamics STEM Lab (BIO02)! Designed for Middle School Life Science, Biology, Human Anatomy, Math, and STEM classes, this 3-page, print-ready lab packet challenges students to construct and test a functional mechanical heart chamber model.

What Is Included in This 3-Page Packet?

• 📋 Page 1: Teacher Guide & Lesson Plan

  Features NGSS alignment (MS-LS1-2 Cell & Body Systems, MS-LS1-3 Subsystems Interaction, MS-ETS1-2 Engineering Design), key cardiovascular biomechanics concepts, fluid testing setup directions, expected learning outcomes, cleanup rules, and a full teacher answer key.

• 🫀 Page 2: Student Mission Card & Blueprint

  Hooks students with an artificial heart medical device scenario. Includes material constraints (jar/cup, balloon membrane, drinking straws, tape, rubber band, colored water, graduated cylinder, timer) and a dedicated schematic sketching zone to diagram chamber pressure, flexible diaphragm contraction, and one-way valve flow direction.

• 📊 Page 3: Testing Log & Scientific Reflection

  Features a structured lab data table tracking total squeeze cycles (beats), total fluid output in milliliters, calculated stroke volume (mL per beat), and valve backflow observations. Includes an applied math section to calculate Stroke Volume and Estimated Cardiac Output (mL/min = Stroke Volume x Beats Per Minute), followed by reflection questions analyzing pressure differentials and valve regurgitation prevention.

Educational Value & Key Benefits:

• Hands-On Cardiovascular Physics: Connects cardiac muscle contractions and valve mechanics directly to pressure differences and liquid displacement.

• Integrates Applied Math & Volumetric Rates: Teaches students how to convert liquid volume measurements into stroke volume averages and rate-over-time formulas.

• Low-Cost High-Engagement STEM: Uses accessible items like jars, balloons, straws, rubber bands, and food coloring for an unforgettable life science lab across Grades 6–8.
