&lt;p&gt;Mammals are creatures who give birth to their young ones as opposed to other animals who lay eggs. Birds, reptiles and insects lay eggs. But as with every other rule, this one has exceptions* too.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;An exceptional exception&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;The duck-billed platypus of Australia walks out of fresh waters to build its nest on the ground. But it has retained its love of water and returns to streams and ponds to eat crayfish, snails, and shrimp. The most remarkable feature in the platypus is that although it is a mammal, it lays eggs!&lt;/p&gt;</description></item><item><title>What is Cloning?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-cloning/</link><pubDate>Sun, 07 Sep 2003 11:55:52 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-cloning/</guid><description>&lt;p&gt;Which is the most famous sheep in the world? A sheep called Dolly. But why is Dolly famous?&lt;/p&gt;
&lt;p&gt;That is because unlike other sheep&amp;rsquo;s, Dolly was not born in the usual manner. She is actually a carbon copy of her mother, like an identical twin. This means that she is the twin sister of her mother who is older by six years and she does not have a father!&lt;/p&gt;

The line ran from the ceiling to the wall behind my bed and then disappeared under it.&lt;/p&gt;
&lt;p&gt;As I watched, I saw one of the dashes move. It was a small red ant walking up the line. Soon, another one followed and then another, till it grew into an army of ants marching up the wall.&lt;/p&gt;
&lt;p&gt;I noticed that while walking in a line the ants were cleaning the wall paint underneath them and, in the process, making a path. And there is a very good reason for them walking in a line.&lt;/p&gt;</description></item><item><title>What is Water Harvesting?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-water-harvesting/</link><pubDate>Fri, 09 May 2003 05:03:49 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-water-harvesting/</guid><description>&lt;p&gt;Come summer and the entire nation seems to have just one word on its lips – water.

&lt;p&gt;Fresh water, they say is a scarce resource. Is it?&lt;/p&gt;
&lt;p&gt;During the monsoons every year, we allow huge amounts of fresh water to run off our roads and pavements into the drains where it mixes with the sewage and heads straight for the rivers where we dump waste. Did you know that this rain water is enough to see us through the summers?&lt;/p&gt;</description></item><item><title>Is Potato a Fruit or Vegetable?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-the-potato-fruit-or-vegetable/</link><pubDate>Thu, 02 May 2002 06:52:02 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-the-potato-fruit-or-vegetable/</guid><description>&lt;figure class="image-medium"&gt;

&lt;p&gt;Pick up a potato and you notice eyes with little lashes on it. In fact, the lashes look like tiny roots. Have you ever wondered why the potato has roots on it?&lt;/p&gt;
&lt;p&gt;The potato is actually a stem. A stem in disguise, that grows under the ground!&lt;/p&gt;
&lt;p&gt;Many plants are masters at adapting themselves to their surroundings. They can change their structure to suit their needs.&lt;/p&gt;</description></item><item><title>Himalayas Have a Deep Impact on the Climate of the World</title><link>https://www.pitara.com/science-for-kids/planet-earth-for-kids/himalayas-have-a-deep-impact-on-the-climate-of-the-world/</link><pubDate>Sun, 27 Oct 2002 03:58:51 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/planet-earth-for-kids/himalayas-have-a-deep-impact-on-the-climate-of-the-world/</guid><description>&lt;p&gt;Tibet is known as the roof of the world.

&lt;p&gt;Besides being the roof of the world, this plateau also has a deep impact on the climate of the world, says a report published in the May, 2001, edition of &lt;em&gt;Nature&lt;/em&gt;, a science and environment journal.

&lt;p&gt;All the food we eat goes into our stomach. Here, it is broken into smaller and simpler substances and get absorbed into the blood. Then, the blood carries these food particles to the different cells of the body, where they are used to provide energy to our body.&lt;/p&gt;

&lt;p&gt;Which is the planet farthest from the Sun? For a long time, the answer was Pluto. Not any more.&lt;/p&gt;
&lt;p&gt;In 2006, the world&amp;rsquo;s astronomers met and agreed on exactly what a &amp;lsquo;planet&amp;rsquo; is. Pluto did not fit the new rules, so it was given a new title — a &lt;strong&gt;dwarf planet&lt;/strong&gt;.&lt;/p&gt;
&lt;p&gt;Why the change? Mostly Pluto&amp;rsquo;s small size. It is only about 2,377 kilometres across — about five times smaller than Earth, and even smaller than our own Moon. Scientists had long suspected that something so tiny did not belong in the club of major planets.&lt;/p&gt;</description></item><item><title>How Far Away are the Stars?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/how-far-away-are-the-stars/</link><pubDate>Thu, 04 Dec 2003 12:42:03 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/how-far-away-are-the-stars/</guid><description>&lt;figure class="image-medium"&gt;

&lt;p&gt;The sun is a star, just like the thousands of others we see in the sky each night. But it looks so very big. Is it the biggest star? No. The only reason the sun appears so big is because it is closer to us than any other star.&lt;/p&gt;
&lt;p&gt;The sun is just 93,000,000 miles (or 14,88,000,000 km) away from the earth. That seems an awful lot of distance, but light can travel so quickly that the sun&amp;rsquo;s rays reach the earth in a little more than eight minutes! That is the wonder of light.&lt;/p&gt;</description></item><item><title>Why does Milk spill over when it Boils?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-milk-spill-over-when-it-boils/</link><pubDate>Wed, 09 Oct 2002 20:50:36 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-milk-spill-over-when-it-boils/</guid><description>&lt;figure class="image-medium"&gt;

&lt;p&gt;How many times have you seen milk boil and spill over, and wondered why this happens? To answer this question we have to know a little more about the composition of milk.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Milk and its composition&lt;/strong&gt;&lt;br&gt;
Unlike water, milk is not a simple liquid. It is a colloid and contains many substances in suspended form. These substances are mainly protein, sugar and fat. When milk is heated slowly, the proteins and fat get separated. Since they are lighter than the milk they collect on the surface in the form of a layer called cream.&lt;/p&gt;</description></item><item><title>A Fish with Three Hearts: Cuttlefish</title><link>https://www.pitara.com/science-for-kids/planet-earth-for-kids/a-fish-with-three-hearts-cuttlefish/</link><pubDate>Mon, 18 Mar 2002 05:06:42 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/planet-earth-for-kids/a-fish-with-three-hearts-cuttlefish/</guid><description>&lt;p&gt;It is said to be a royal among sea animals because it has blue blood, literally. And the cuttlefish has a large heart. Actually, it is not one but three hearts.&lt;/p&gt;
&lt;p&gt;And it is not even a fish but belongs to the same family as the squid and the octopus. They are called the cephalopods, which literally translated means head-foot.&lt;/p&gt;
&lt;p&gt;The blood of the cuttlefish is blue because of the huge amount of copper in it. While it uses two of its hearts to pump blood into the gills (the lung of the fish) where it absorbs oxygen, the third heart pumps blood into the other organs.&lt;/p&gt;</description></item><item><title>How does a Submarine Work?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/how-does-a-submarine-work/</link><pubDate>Sat, 12 Apr 2003 20:16:50 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/how-does-a-submarine-work/</guid><description>&lt;figure class="image-medium"&gt;

&lt;p&gt;Nine &amp;lsquo;o&amp;rsquo; clock. It&amp;rsquo;s time for your favourite serial on television. Have you ever wondered how the same serial can be viewed by millions of people across the world?&lt;/p&gt;
&lt;p&gt;This is possible because of satellite television technology. It uses man-made or artificial satellites to send your favourite serial to your television set.

&lt;p&gt;As you stand in the middle of a playground or while you are sitting in your class, there is an immense weight right over your head, but you do not feel it! This is the weight of the atmosphere, or air, as we know it.&lt;/p&gt;
&lt;p&gt;Composed of nitrogen, oxygen, carbon dioxide and other gases, it surrounds the earth like an envelope. And, it extends almost a thousand kilometres above the Earth&amp;rsquo;s surface.&lt;/p&gt;</description></item><item><title>An Organism that is visible from Space</title><link>https://www.pitara.com/science-for-kids/planet-earth-for-kids/an-organism-that-is-visible-from-space/</link><pubDate>Sat, 10 Aug 2002 10:30:36 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/planet-earth-for-kids/an-organism-that-is-visible-from-space/</guid><description>&lt;p&gt;The elephant is the largest land animal. The Blue whale is the largest sea animal. But however big these animals may be, they can not size up to the colonies built by tiny little sea creatures – the coral. The colonies built by corals are called coral reefs. Coral reefs can be as huge as big islands or even as big as a country!&lt;/p&gt;
&lt;p&gt;These reef-building corals are not single animals. A coral is a colony made up of many individual animals called polyps. These are connected to each other.&lt;/p&gt;</description></item><item><title>How do Earthquakes Happen?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/how-do-earthquakes-happen/</link><pubDate>Thu, 15 Aug 2002 04:16:22 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/how-do-earthquakes-happen/</guid><description>&lt;p&gt;Simply put, the shaking of the earth caused by a sudden shifting of rocks below its surface, is called an earthquake. The earths crust or outermost layer, is not made of one single piece of solid rock. It is actually made up of independent sheets of rocks called tectonic plates.&lt;/p&gt;

&lt;p&gt;On beaches as well as on the cricket ground, it is always possible to spot people with some kind of cream on their bodies or faces. Remember the South African pace bowler Alan Donald or &amp;lsquo;White Lightning&amp;rsquo; as he is called, with &amp;ldquo;war-paint&amp;rdquo; on his face? No, it is not an attempt at camouflage, simply an effort to gain protection from the ultraviolet rays of the sun.&lt;/p&gt;</description></item><item><title>Why do We Cup Our Hands When We Shout?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/why-do-we-cup-our-hands-when-we-shout/</link><pubDate>Wed, 21 Aug 2002 23:23:05 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/why-do-we-cup-our-hands-when-we-shout/</guid><description>&lt;figure class="image-medium"&gt;

&lt;p&gt;The Mammoth, almost twice the size of a modern African Elephant, charged and stomped.

&lt;p&gt;Dolphins and whales live in the deep blue sea, but strangely these animals are not able to see the colour blue!&lt;/p&gt;
&lt;p&gt;Leo Peichl of the Max Planck Institute for Brain Research in Frankfurt and his colleagues discovered during routine tests that seals do not respond to the blue colour. Intrigued, they carried out similar tests on few other species, such as dolphins and whales, and found the same results.&lt;/p&gt;</description></item><item><title>Why is the Ball-point Pen Called So?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/why-is-the-ball-point-pen-called-so/</link><pubDate>Tue, 14 Oct 2003 05:05:22 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/why-is-the-ball-point-pen-called-so/</guid><description>&lt;p&gt;Writing is one of the most important inventions. Humans first used brushes for writing, then thick reeds were used. Feathers were used in medieval Europe for writing.&lt;/p&gt;
&lt;p&gt;In the mid-19 century, metallic pens and nibs were widely used, while the fountain pen was produced in 1884 by the American, LE Waterman. However, these pens had a lot of problems. The ink would spill and blot very frequently and writing was cumbersome.&lt;/p&gt;
&lt;p&gt;The first ball-point pen was invented by an Hungarian journalist, Ladislo Biro, in 1938. Biro had noticed that the type of ink used in newspaper printing dried quickly and did not smudge the paper. He decided to make a pen using the same type of ink. However, that thick ink could not flow through the normal pen nib, so he tried something else. And that is how the ball-point-pen was born.&lt;/p&gt;</description></item><item><title>Everything is made of something</title><link>https://www.pitara.com/science-for-kids/planet-earth-for-kids/everything-is-made-of-something/</link><pubDate>Wed, 04 Sep 2002 14:54:10 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/planet-earth-for-kids/everything-is-made-of-something/</guid><description>&lt;p&gt;How do you make tea?

&lt;p&gt;Everything that is born must die. Not only living beings, but inanimate objects like stars too.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;The birth of a star&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;The universe has massive clouds of hydrogen floating around. Sometimes, these clouds come together and form very dense and huge balls of hydrogen gas. As the clouds come close, their temperature increases. This is called a proto-star (original star).&lt;/p&gt;
&lt;p&gt;The increase in temperature triggers off nuclear reactions at the core of the star. Nuclear reactions inside the star occur when the nucleus of two hydrogen atoms fuse to produce a helium atom. This reaction which is actually the same as that inside a hydrogen bomb, release huge amounts of heat and light. This is what makes a star glow.&lt;/p&gt;</description></item><item><title>All Human History is Just 10 Seconds Old!</title><link>https://www.pitara.com/science-for-kids/planet-earth-for-kids/all-human-history-is-just-10-seconds-old/</link><pubDate>Fri, 14 Dec 2001 05:37:22 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/planet-earth-for-kids/all-human-history-is-just-10-seconds-old/</guid><description>&lt;p&gt;Look at the dial of a clock.

&lt;p&gt;We know very little about what happened in the first three hours of the earth&amp;rsquo;s existence. The first signs of life appeared in the form of bacteria when the earth was four hours old.&lt;/p&gt;
&lt;p&gt;Then came the first vertebrates (animals with skeletons). They were born when the earth was 10 hours and 35 minutes old. The huge dinosaurs arrived at 11 hours and 25 minutes and birds and mammals at 11 hours and 50 minutes.&lt;/p&gt;</description></item><item><title>Why does a Cricket Ball Swing?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-a-cricket-ball-swing/</link><pubDate>Sun, 11 Mar 2001 20:21:37 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-a-cricket-ball-swing/</guid><description>&lt;p&gt;How many times have all of us heard that the former captain of the Indian cricket team, Kapil Dev, was one of the greatest out-swing bowlers of all times. Indeed! He took more than 430 wickets in Test cricket. But, do you know how a cricket ball swings?&lt;/p&gt;
&lt;p&gt;The term &amp;lsquo;swing&amp;rsquo; refers to the movement of the cricket ball in the air after it leaves the bowler&amp;rsquo;s hand, which takes the ball away from or towards the batsman. If the ball moves away from the batsman it is called an out-swinger; if the ball moves towards the batsman it is called the in-swinger.&lt;/p&gt;</description></item><item><title>What is a Kangaroo Rat?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-a-kangaroo-rat/</link><pubDate>Mon, 17 Jun 2002 14:37:03 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/what-is-a-kangaroo-rat/</guid><description>&lt;p&gt;It looks like a small kangaroo for its hind legs are longer than its fore legs.

And that&amp;rsquo;s why it is called the kangaroo rat.&lt;/p&gt;

&lt;p&gt;To overcome the problem of identifying books, publishers have came up with a unique numbering system. For instance, if 50,000 copies of &lt;em&gt;The Adventures of Sherlock Holmes&lt;/em&gt; are printed by a publisher at one time (called an edition), all of them are identified by one number code. This number code is like your home address that cannot be shared by anyone else apart from your parents and siblings.&lt;/p&gt;</description></item><item><title>Tiger Move</title><link>https://www.pitara.com/fiction-for-kids/folktales/tiger-move/</link><pubDate>Wed, 10 Jan 2001 02:44:51 +0000</pubDate><guid>https://www.pitara.com/fiction-for-kids/folktales/tiger-move/</guid><description>&lt;p&gt;&lt;em&gt;Santhals are a tribe found in rural Orissa and West Bengal.

And an object that does not reflect light is called opaque.&lt;/p&gt;</description></item><item><title>Why does a Kentish Plover Parent Desert its Family?</title><link>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-a-kentish-plover-parent-desert-its-family/</link><pubDate>Wed, 27 Feb 2002 19:03:49 +0000</pubDate><guid>https://www.pitara.com/science-for-kids/5ws-and-h/why-does-a-kentish-plover-parent-desert-its-family/</guid><description>&lt;p&gt;When couples exchange vows on the marriage day, they generally say &amp;rsquo;till death do us part&amp;rsquo;.

A recent study conducted by Andras Kosztolanyi of the University of Debrecen, in Hungary, sheds light on the reason behind this behaviour.&lt;/p&gt;</description></item><item><title>Screen Saver that saves</title><link>https://www.pitara.com/news-for-kids/world-news/screen-saver-that-saves/</link><pubDate>Tue, 19 Mar 2002 21:46:12 +0000</pubDate><guid>https://www.pitara.com/news-for-kids/world-news/screen-saver-that-saves/</guid><description>&lt;p&gt;You can find a cure for cancer.
