In cold winter months, lakes and rivers freeze over forming ice. Yet, fish and other aquatic animals manage to survive.
Animals like seals, penguins, walruses and a wide variety of sea birds are all fish eaters. They live in the Arctic and Antarctic Circle, amidst the icecaps. The land is completely frozen. Yet these animals manage to live in this region. How do they do it?
The icy waters of the Arctic and Antarctic Oceans support a great amount of marine life....
William Shakespeare (1564 - 1616): “Neither here nor there”, “with bated breath”, “vanish into thin air”… Words we use today, but they were written by one very talented writer nearly 500 years ago. The English language as we know it today owes a lot to William Shakespeare.
William Shakespeare is considered the greatest writer in the English language and the greatest playwright to have ever lived. Born on the 26th of April 1564, his complete works include 39 plays and 154 sonnets....
As day breaks, a reddish-white ball of light that we call the sun, rises. This red haze gives way to a golden-white sheen as the day advances and reappears when the sun sets in the evening. Does the sun really change colours, or does it only seem so? The explanation lies in-between.
Light from the sun consists of three kinds of radiation – ultra-violet rays, visible light and infra-red rays. Unlike visible light, ultra-violet rays and infra-red rays cannot be seen....
Viruses are these tiny, invisible structures that cause infections. They make us sick. There are millions of viruses in our environment but only about 5000 have been identified by scientists. The ones you may have heard of are the Human Immunodeficiency Virus or HIV and the Novel Coronavirus or Covid-19.
What do viruses look like? Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) illustration, created at the Centers for Disease Control and Prevention (CDC) Do you think that a virus is some creepy, crawly thing?...
Amelia Earhart was one of the world’s most celebrated aviators. She broke records and charted new skies in the course of her short life. She disappeared while she was on a flight around the world.
Earhart was born on July 24, 1897, in Atchison, Kansas. She was the elder of Edwin Stanton and Amy Otis Earhart’s two daughters. Childhood was not happy for the two bright sisters. Their father was an alcoholic and lost jobs often....
The history of writing instruments with which humans have recorded and conveyed thoughts, feelings and grocery lists, is the history of civilisation itself. This is how we know about our ancestors and their lives.
The handy sharpened-stone, used for skinning and killing animals was adapted into the first writing instrument. Around 24,000 BC, the cave man started drawing pictures with the stone onto the walls of his cave dwelling. His drawings showed events in daily life such as the planting of crops or hunting victories....
We deal with numbers all the time. Not just while doing math lessons at school, but also while counting money at the shop, memorising the numbers of our favourite TV channels or even keeping tabs on the number of hours we spend in front of the Internet! But we are so used to numbers that it has never occurred to us to find out where these numbers come from.
For that, we must travel back in time....
Satyanshu Mohan is student St. Joseph’s Intermediate College at Allahabad and is studying in class four. Here he recounts his trip to Nainital with his family.
Nainital is a beautiful hill station in Himalayas. My father is very fond of Nainital. This year we went just after Deepawali to Nainital on a short trip. There is no direct suitable connection by train to Nainital from Allahabad so we first went to Rampur and then from there we took a train to Kathgodam....
The summer sun smiles a scorching smile
The smile sends shivers
through the stoutest hearts
A summer smile is reason to sweat
But the potter’s back with his cool lifeline!
Earthen pots of every size
Are piled under a tarpaulin sky
Waiting to find new homes
And soothe thirsty throats!
Their water has a magical taste –
The sweet smell of wet earth
Or soil that comes alive after
The first seasonal shower!
The Potter [Illustration by Shinod AP] Some pots are small, like a baby’s song...
People often wonder whether an earthquake can drastically change the topography of a region. A few tremors and some buildings that collapse does not mean that the shape of the earth has changed, does it? However, earthquakes can and do change the topography of the region.
An earthquake raised Rhodes island. The line of erosion (on the rock to the left) shows the sea level before the earthquake. The rise is uneven in different parts of the island, usually several meters....
