Where Do Penguins Live?
Short, fat and looking as if they were attending a formal dinner dressed in a tuxedo, penguins could easily be mistaken for people from a distance! Penguins are flightless birds found in the southern hemisphere. No, they are NOT found near the North Pole. Scientists feel that these birds became flightless as food was available in plenty. But their food was located underwater so they adapted to the sea with short flipper-like wings. Where Do Penguins Live?...
How do Humans Balance on Two Legs?
Four-year-old Rohit couldn’t understand why his parents and grand parents were so happy on seeing his 10-month-old sister, Ruchi, take a few unsteady steps towards her favorite toy. What was so unusual about her walking -after all, he could walk and run without anyone’s help, yet no one ever clapped nor hugged him, the way they were doing it for his sister. Unable to hold his curiosity any longer he decided to talk about it to his closest friend and guide – his mother....
Why do Beavers Build Dams?
Picture a giant rat with a flat tail and webbed feet. That’s what the beaver looks like. There are two kinds of beavers: the American and the European. The European beaver, found in Norway, Poland, Germany and France, lives in burrows. But the American beaver builds a dam across a stream or lake to construct his home or lodge. The lodges are made of huge logs of trees. Why do Beavers Build Dams? [Illustration by Sudheer Nath] The American beaver constructs solid dams and lodges because it has the mind of an expert engineer among all the creatures in the animal kingdom....
Can Two People have Identical Fingerprints?
I was once watching a detective serial on T.V. where the fingerprints of the suspect are required. The hero invites the villain to his home and offers him a glass of water. The bad guy takes the glass and drinks the water from it. After he leaves the hero dramatically whips out a handkerchief and picks up the glass. His expressions showed that satisfaction at a job well done. At that time, I found it amazing – how can smudges on a glass identify people?...
How Many Kinds of Rhinos are There?
A modern day rhino or rhinoceros looks pretty much like its ancestor that existed on earth more than 30 million years ago. Its status as an animal “biggie” hasn’t changed much either. The ancestors of the modern-day rhinoceros – the 4 feet tall Uintatherium and the 15 feet high Indricotherium – were the largest land mammals ever. Today’s rhino is the largest living land mammal, after the African elephant, in terms of size and weight....
Why do Onions Make us Cry?
One of the earliest memories I have as a child is when I was approximately three or four years old. I remember watching my mother work in the kitchen. She was cutting onions for the salad and I could see tears in her eyes. For a child the worst possible thing is to watch his/her mother cry. I got so upset that I got hysterical at my father for causing her pain. For I assumed my father was somehow responsible as we were only the three of us in our family....
The Hows and Whys of Bubble Gum
Chew this question: What is small and pink, tastes sweet, can be chewed for hours without it dissolving, yet is not to be swallowed? Some doctors feel that it helps to relieve stress. Others think it is good for the teeth. Americans are constantly rolling it about in their mouth and the US army gives it as part of field rations. No guesses for the correct answer. Yes, it is chewing gum or bubble gum as it is often called because you can blow large bubbles that go ‘pop’!...
When will the Oceans of the Earth Overflow?
Try this out. Plug the sink and leave the water running. It will lead to a flood in the bathroom and a scolding for letting the water overflow. Since the sink could not hold an unlimited amount of water, it let the water spill out. But even the oceans are enormous bodies of water that get flooded with water from rain, melting ice, and rivers year after year. Will they start overflowing too? If so, when?...
Why do Earthquakes Occur?
As a result of upheavals below its surface, the earth shakes now and then. This shaking of the earth is known as an earthquake. Few natural events are as violently destructive as an earthquake. It usually strikes without warning, giving off violent vibrations in the process. These vibrations not only shake the ground but also sometimes crack it open. And then, there is chaos, for earthquakes have been known to wipe out cities and civilisations....
What is the Secret of the Windmill?
It was a particularly windy day in late July when my cousin and I sat down to make a pinwheel. The paper was folded into a wheel, the pin inserted at the heart of it and the entire structure fixed to the broomstick. As our pinwheel took shape we ran out braving the sun and the hot wind. The pinwheel caught the wind and rotated. Seeing it, our hearts pin-wheeled as well. Energy from wind...
