On 16 April 2025, the Cambridge learners of Grade V embarked on an illuminating scientific journey within the school’s state-of-the-art laboratory. The focal point of this engaging observation activity was a detailed 3D working model of the human heart. Students examined vital components such as the atria, ventricles, valves, and major blood vessels, gaining a comprehensive understanding of the heart’s structure and function. Guided discussion and hands-on exploration brought the circulatory system to life, revealing how blood transports oxygen and nutrients throughout the body. This multisensory learning experience nurtured curiosity, fostered critical thinking, and catered to diverse learning styles, making biology both captivating and accessible.
