Science with Paper
Paper may have been invented to write on, but it is much more versatile than that! Various grades, colours, sizes, shapes and textures of paper have allowed artists, mathematicians and scientists to cherish it as much as the writer and poet! Folding, bending, rolling, creasing, cutting and gluing: our hands have immeasurably expanded their dexterity by playing with paper and using it in myriad ways. However, paper is made from wood – taken typically from precious rainforests – and its use should be reduced, reused and recycled as much as possible. Today, most of the paper we get in the market is recycled. However, it is only our behaviour which will determine whether we can reduce the use and reuse paper.
In this Theme of 3 Open TACtivities, which cover concepts in physics, chemistry and biology, we recommend that you make them with already used paper/cardboard. Using filter/tissue paper, you will learn how to separate colours of your sketch pen; a cool adaptation of a protractor using cardboard will allow you to measure the angular range of your various body joints; and you will also get to make your very own camera, with a projection screen! So the next time you see paper thrown away – or just lying around about to be – make sure you pick it up, and if not write a poem on it, at least play with it to delve into the world of science…
