Important Questions on Resources for Teaching and Learning Science
Read the following which appears in Class VIII NCERT Textbook:
Nylon appears like silk. It is strong and flexible. These endearing qualities of nylon created a public sensation, or nylon mania when it was introduced in 1939. Women's stockings made from this new fibre were in great demand. But, unfortunately, most of the nylon productions had to be diverted to making parachutes during the Second World War (1939-1945). After the War, when the production of stockings resumed, supply did not match the demand. There was a huge black market for this product. Women had to wait for hours in queues to get a pair. Often there were 'nylon riots'.
What are the significances of including the above in the Science textbook?
I. To develop a historic perspective in Science and the development of ideas.
II. To develop an appreciation of how new inventions create new demands.
Ill. To develop a holistic understanding of Science.
IV. Including such anecdotes makes the Science textbook light and easy.
