Which kind of clothes people wear in hot climate?

You are midway through your soccer game, and the sun is beating down on you. Sweat drips off your forehead. To keep cool, you are wearing a T-shirt and short.

In warm places, people wear clothes made of a lightweight material, such as cotton or linen, to stay cool. Many of the clothes in warm regions are white or light-coloured, because these colours reflect the sun’s rays. Darker colours absorb heat from the sun, so they make a person feel hotter.

A man rides a long-legged camel across the Sahara. The sun burns bright and hot. This man is a Tuareg. He rears animals in the desert. A light blue robe covers him from shoulders to ankles. The loose folds of the robe shield him from the hot sun. They also let air flow around his body, helping to keep him cool. He has a long cloth wrapped around his head. Part of the cloth can be pulled over his mouth and nose to keep out blowing sand. Just as your lightweight clothes keep you cool in the hot sun, this man’s clothes protect him from the weather.

Which kind of clothes people wear in cold climate?

Brrrrrrr, it’s cold outside! You have to go out and play. What do you wear to keep warm? Perhaps you wear a heavy coat, hat, scarf, gloves or mittens, and warm boots.

Some people must wear warm clothes most of the time. People in northern Canada, Greenland, and other places that are far north live in climates that are cold most of the year. In these cold regions, people wear heavy clothes made of fur or wool.

An Inuit man wears clothes made from animal skins. A hooded jacket, or parka, protects the top part of an Inuit’s body. Can you guess what he wears under his jacket? Another jacket! He also wears two pairs of trousers to protect his legs. The heat from his body stays between the two layers of clothes, and this helps to keep him warm. Thick fur mittens protect his hands, and he wears sealskin boots on his feet.

What is an Airport?

The day has finally arrived! You are at the airport and about to board the plane that will take you on your dream holiday. There are many things you need to do at the airport before takeoff.

At the check-in counter, an airline worker checks you in, tells you which seat is yours, and gives you a boarding pass. Your luggage is put onto a moving belt. It carries your suitcase through rubber flaps in the wall to large bins that are wheeled to the plane. You are told which departure gate your plane will leave from.

At the security check, you and other travellers may also pass through a gate that has special machines. The machines make sure nobody is carrying anything dangerous.

At the departure gate, another airline worker takes your boarding pass. You are ready to board the plane.

You may have to walk through a tunnel or upstairs to get to the plane. When you enter the plane, a flight attendant helps you find your seat. There is a bin above your head in which to put your coats, small bags, or toys. Of course, you fasten your seat belt!

Suddenly the plane’s engines roar to life. The plane is moving! Slowly, at first, then faster and faster down a long paved path called a runway. Finally, you’re up in air! Sit back and enjoy the ride.

Why do people fly?

Aeroplanes and helicopters are two ways to get far in a hurry. They carry people and goods thousands of metres above the ground.

The first thing you might notice about an aeroplane is its wings. When an aeroplane starts moving, the special shape of its wings helps it rise in the air and fly. Under the aeroplane wings are its engines. The fastest planes have jet engines that help them travel halfway around the world – from Chicago, Illinois, to Kolkata (Calcutta), India – in about 15 hours! Sometimes people can watch a film, listen to music or eat a meal or a snack while flying in the clouds.

Helicopters do not have the same type of wings that aeroplanes do.  A helicopter is powered by whirling blades that lift it into the sky. Helicopters are not as fast as most aeroplanes, but they can change directions and land more easily. They can fly forwards, upwards, and sideways. They can also hover, or stay in one place in the air.

The world’s largest passenger aeroplane, the Airbus A380, made its first commercial flight in 2007. The Airbus can seat more than 525 passengers.

Why do people travel by train?

They can move people at speeds of more than 320 kilometres per hour. They carry goods weighing thousands of tonnes across a continent. Almost every country has them, and many children collect toy models of them. What are they? Trains!

Every day, in many places throughout the world, trains carry thousands of people along railway tracks. People who want to travel from one city to another use trains. Many people who live in one town and work in another take a train to work. Some trains make longer trips. They have beds for sleeping and serve meals in dining cars.

Subways are underground city trains that zoom people from place to place. Elevated trains crisscross a city on tracks that are built above the streets.

Where do boats begin and end their voyages?

You’re at a place where there are lots of things to see, hear, smell, and taste. You can hear the cawing of hungry sea birds.

You can see boats loading and unloading, tiny tugboats pulling enormous ships, and sailors getting ready for a cruise. Where are you? At a harbour!

Boats and ships begin and end their voyages at a harbour. A harbour is a protected body of water. Some harbours are partly surrounded by land. The land protects them from dangerous ocean waves and strong winds. Other harbours are built near narrow channels of water. On open coasts, huge walls are built to protect a harbour.

At a harbour, you might smell the salt air and motor fuel. At small harbours, people dock and refuel their boats. These harbours may have ramps that people use to unload the boats from car trailers. Other harbours are big enough to hold many large ships and barges.

Clang clang clang. The captains of boats and ships carefully move their vessels around the clanging coloured buoys. The buoys warn them of dangerous places, such as shallow, water and rocks.

If you are lucky, the harbour might even have a snack bar with delicious seafood to taste!
