Air is essential for all the living beings to stay alive. Students of Class-I were briefed on the importance of Air and its properties through some experiments. In one of the experiments, the teacher showed the children a balloon and blew air in to it. She asked the children to watch carefully how the balloon gradually took shape. She then asked the students to share on what their observation was during the experiments. Some of the students said that the balloon became big in size and some said it took an oval shape. They were explained that the size of the balloon increased as it was filled with air and concluded that AIR FILLS SPACE, which is one of its property. For the next activity, the teacher took two candles, a glass and a match box. She lighted both the candles and placed it on the table. She then covered one of the candles with a glass and the other remained uncovered. The children observed that the candle covered with the glass stopped burning whereas the uncovered one continued to burn. Children were excited to see the activity. On being asked the reason for the candle to stop burning, the children promptly answered AIR and said less air was present inside the glass and it was exhausted by the candle. The students clearly understood that the candle stopped burning because there was no air, whereas the other candle kept burning due to sufficient air, which is another property of air. AIR HELPS IN BURNING. In the next activity, the teacher took two hangers and two balloons. She filled air in one of the balloons and tried each balloon to each end of the hanger. She then asked what did the children understand by this experiment and can they correlate this arrangement. Children answered that it looks like a Beam Balance which is used to weigh things. Children then observed the hanger leaning towards the air-filled balloon. The children promptly answered that the balloon with air is heavier so the hanger is leaning down. Thus, the children understood about another property of air, that AIR HAS WEIGHT. Students had a wonderful learning time observing the experiments to learn about the properties of air. They were eager to do these activities on their own. These experiments enhance the logical, visual and naturalistic skills of the children.
