Engagements and hands on experience are ways to make the learners get acquainted with new learning in a better manner. Through the transdisciplinary theme of How the World Works, PYP 3 is inquiring into how materials change to create a final product. We spent a day conducting several experiments during our finding out inquiry phase, to better understand properties of the three main phases of matter: solids, liquids and gases. We then applied our understanding of matter by creating a substance new to us. Learners had great fun while performing various experiments. They were great inquirers while observing the balancing stick weighing the different types of balloons. This helped them conclude that every matter has weight; Air occupies space and has weight. They also felt that the more amount of air the weight of that balloon was more than the smaller or deflated balloon. They also saw a candle getting extinguished when a glass is covered it, paper turning into ash when burnt etc. Learners were seen thoroughly enjoying the activity.
