What it isEngage students in real-time discovery of how their body systems (Circulatory, Respiratory, Muscular, Skeletal, etc) work together during exercise. This ready-to-teach lesson blends science, health, and exercise into a dynamic, data-driven experience that deepens understanding of body systems and builds health literacy—without the need for complex equipment. It positions students as "Body System Detectives" conducting a scientific investigation using their own bodies as the laboratory.
