We had asked you, dear readers, to tell us how you're keeping your kids busy indoors during the COVID-19 lockdown.
Rediff reader Palanki Suryanarayana, 75 a retired professor of civil engineering settled in Bengaluru, tells us how he is teaching science to his grandson.
During the lockdown I taught my grandson some science.
The first experiment was about static electricity.
After vigorously rubbing an inflated balloon over his scalp, the balloon was raised a little above causing the hair to stick up. A truly hair raising experience!
The second experiment was about magnetism using a fridge magnet and some rupee coins.
The nickel coins were placed in a row touching each other and the magnet was brought near. The entire chain of coins stuck to the magnet.
Adithya learnt two things:
1. Nickel is a magnetic material
2. When attached to the magnet, the nickel coin itself becomes magnetic and can attract other coins.
I also learnt how nickel is still being used for minting coins, a practice I thought ended with the King George VI four anna pieces!
In the third experiment, we focused on the effect of sun's rays on the head of a match stick. We had placed some sticks on the dry leaves and used a convex lens to light it up.
Adithya learnt that light rays and heat rays have the same point of convergence.
After physics, we did a little bit of nature study.
My grandson learned about camouflage in nature by observing a butterfly disguised as a dry leaf of our potted plant.
