Paper Making activity


As part of the unit on pollution, ozone layer depletion and global warming, grade 7 did a practical activity on recycling paper. One of the prime causes of global warming is “deforestation” as forests are great storehouses of carbon and when these are destroyed – it adds to the global warming. One of the reasons that trees are cut is to make paper. As individuals – we can contribute in controlling the global warming by following the 3 Rs – Reduce, Recycle and Reuse. The practical activity gave us an insight on how paper is recycled. For this activity, students have bought screens. They got some used paper and then blended it with water using a normal household blender. The pulp thus obtained was transferred on the screen and the water was drained out assisted by rolling a cylindrical tube over the pulp and in the process flattening it to form a sheet of paper.
     The damp sheet was then placed between two pages of a newspaper to soak up the remaining water. A tile was placed to apply pressure and assist in bonding and flattening the surface to make it as even as possible. After a few minutes They took out the tile and the top layer of the newspaper and dabbed the recycled sheet of paper with a piece of cloth to absorb any moisture left behind. Children then used a hairdryer to dry the sheet completely and then they carefully lifted the recycled paper sheet from the newspaper.The principle of reusing was followed diligently and the water that was drained in the process of making the first sheet was reused as the process was repeated to make another sheet of paper. The students passed on the screen to their classmates so that each one could do this activity. Thus the equipment was shared by the whole class.

            Through this activity, They appreciated paper – that we take it for granted – in a new light. They also realized that as individuals they can make a significant contribution by using paper carefully and thus saving forests. This activity made them knowledgeable which is one of the important part of IB Profile.
They  thoroughly enjoyed this activity and the experiential method that was followed made it easier for them to understand the topic.
As the old saying goes “I hear, I know. I see, I remember. I do, I understand”.
