The 5th graders started to build a hot air balloon in Isai Ambalam school. We started gathering information how to make a hot air balloon. Then we watched some videos to make the hot air balloon. We found the reason why the hot air balloon fly towards the sky. The we used tissue papers to make a hot air balloon. The things that are need to make a hot air balloon are glue, tissue paper and binding wire and scissors. we learnt that the hot air moves towards the cold air in the sky and this is the reason why the hot air balloon move towards the sky. I felt the student were excited while doing it . While doing this activity I found the children were responsible for the materials and team work and helping each other and sharing the materials and everyone got equal opportunities for doing the activities.
