Exercise
Energy for Muscle Contraction
In this activity, students will explore how muscles generate the energy needed for contraction by investigating the roles of ATP and creatine phosphate, and by conducting experiments that demonstrate the effects of energy sources on muscle performance. This hands-on learning experience combines biology and chemistry, encouraging critical thinking about how our bodies sustain physical activity.
