Year 9 STEM: Discovering the Human Heart
Last week, our Year 9 students set out to discover one of the most fascinating systems of the human body, the cardiovascular system. As part of their science unit, they explored how the heart functions as the body’s central organ of circulation, keeping every cell alive and active through a complex network of blood vessels.
After learning about the structure and function of the heart, arteries, veins, and capillaries in class, students had the chance to put theory into practice through a hands-on dissection activity. Using a chicken heart as their model, they carefully identified key structures such as the aorta, vena cava, pulmonary artery, and pulmonary vein, the same vessels responsible for transporting blood to and from the heart in humans.
Beyond the scientific knowledge, this activity encouraged critical thinking, teamwork, and scientific inquiry. By combining theoretical understanding with hands-on exploration, students deepened their comprehension and also developed a genuine appreciation for the complexity and beauty of the human body.
It was wonderful to see students’ excitement and engagement throughout this process and I look forward to continue with more experiments in Biology, Physics, and Chemistry, as we keep exploring the fascinating world of science together with our Year 9 class.
