Exploring the Cardiovascular System: An Inquiry-Based Workshop for Pre-Service Teachers

Join us for an engaging workshop led by Darrell Reasner from the Cal Poly SLO Credential Program. This interactive lesson focuses on the cardiovascular system, allowing students to explore how heart valves function in circulation, how gas exchange occurs, and the overall workings of the heart. Students will assemble a model named "Artie" to visualize oxygen delivery and carbon dioxide removal. This inquiry-driven lab is designed for 5th-8th graders and aligns with Life Sciences standards. Discover the wonders of human anatomy and prepare to inspire future generations!

  1. The Cardiovascular System Workshop

  2. Darrell Reasner Preservice Teacher Cal Poly SLO Credential Program dreasner@gmail.com

  3. Objectives: • Have Fun • The history of this unit • The lesson • Learn about the Cardiovascular System • Meet “Artie” • Reflect

  4. Dr. Ed Himalblau Professor Biology Cal Poly SLO Senior Project LBDL Learn By Doing Lab An on-campus laboratory where 5th-8th grade students from local schools can experience real world, standards-based, inquiry-driven science curricula taught by Cal Poly undergraduates planning careers in teaching.

  5. General Description of Lesson: This lesson is designed as an inquiry based lab allowing students to learn the circulatory system. More specifically how and why heart valves produce circulation, where and why gas exchange is done, the functional process of the heart, and how a pulse works.

  6. Content Standards: • Life Sciences • 2b   Students know how blood circulates through the heart chambers, lungs, and body and how carbon dioxide (CO2) and oxygen (O2) are exchanged in the lungs and tissues.

  7. The Challenge:The Cardiovascular System

  8. The Lesson

  9. The Cardiovascular System

  10. One Way Valves Heart Lungs

  11. Capillaries Veins and Arteries

  12. Meet “Artie” • Assemble your model so we can: • Deliver Oxygen (O2) to the brain from the lungs • Then move Carbon Dioxide (CO2) and waste back to the lungs

  13. What did we learn? • Role of one-way valves • Role of circulatory system • Differences between arteries, capillaries, and veins • O2 / CO2 exchange • Heart chambers • Comparison to real heart

  14. Expanded • Comparative anatomy • CPR • The medical field

  15. Artie !
