My daughter, Malu, is asking lot of questions these days. Today she asked us why is it day in India when it’s night in US and vice versa. I didn’t want to say some story and thought I will explain it to her through a demo.
I installed a torch light app in android phone. Then, I took a ball and explained her that it is earth. Then i wrote A on one side and said this is US. Then I wrote I on the other side and said this is India.
We needed a Sun. So we switched on the torch app and I explained to her that earth keeps on rotating like this. So when the light falls on A it’s day in US and no light on India. So night there. When earth rotates and light falls on I it’s day in India and night in US.
She looked all fascinated. I wanted to check how she understood. And asked her the same question. She replied enthusiastically – if it’s light in A no light in I. If light in I no light in A.😃
