FRICTION
Vidya lied down on bed to sleep. But sleep was nowhere near her. She kept staring at the ceiling fan. She wondered, “Doesn't the fan ever wear out?” Well! It never has in the last five years, since Appa fixed it on the ceiling. She went in search of her father with all these thoughts in her mind. “Appa, I was wondering how is it that the ceiling fan has been rotating tirelessly without any wear and tear all these years”, asked Vidya. Mr. Iyer, Vidya's father was very proud of his daughter and her never ending questions. He showed Vidya the inside of an old fan. He pointed out small spherical balls in the fan and told Vidya that these are called ball bearings.
“It is these ball bearings that reduce friction in many machines and prevent then from wearing out quickly”, said appa. Vidya looked confused. “I don't understand how they work”, said Vidya. “Come, let me show you”, said Appa. Why don't you also make the model with Vidya's father? You will need:
Glass marbles, three bottle caps (like those on jam jars) of different sizes, a book.
