All growth depends upon activity.There is no development physically or intellectually without effort and effort means work.Thus to keep the overall growth of students in mind the students of class VI engaged in scientific activity of “Respiration”. The students explained the process of Respiration through inhalation and exhalation. Wherein during inhalation ribcage moves up and diaphragm moves down whereas during exhalation ribcage moves down and diaphragm moves back to it’s original position.
