“Curiosity fuels discovery — even a simple balloon can unveil the invisible weight of air.”
In an engaging and thought-provoking science session, the learners of CIE 5 explored a fascinating concept—proving that air has mass. Through a simple yet powerful hands-on activity, students demonstrated that even something as invisible as air carries weight.
The experiment involved two inflated balloons attached to opposite ends of a makeshift balance using a twist tie and a scale. As one of the balloons was gradually deflated, students observed a visible shift in balance—tilting toward the balloon that remained fully inflated. This visual change clearly indicated that the air that escaped had mass, bringing the concept of gaseous weight to life.
The classroom was filled with excitement as students actively participated in setting up the experiment, making predictions, and observing results. Their enthusiasm and curiosity reflected a strong engagement with scientific inquiry and a growing ability to connect theory with real-world observation.
This activity not only deepened their understanding of the properties of gases but also reinforced that science is best learned by doing. Through simple materials and big ideas, our young scientists took one more step toward mastering the wonders of the physical world.
