Learning Objectives
In this lesson you will:
1.learn some geographical facts about the Sahara Desert.
2.think about what you can do for deserts.
The Sahara Desert
Located in Africa, the Sahara Desert spreads across 30 per cent of the continent. This vast desert, also known as “the great desert”in Arabic, is about 9 million square kilometres in size. It is also at least 4.6 million years old. This means that it is one of the oldest places in the world.
All deserts are dry, and the Sahara is both dry and hot. It is the largest hot desert in the world. We may think that all deserts are hot, but in fact some deserts are very cold! Many scientists believe that Antarctica, for example, is a type of cold desert.
Most of the Sahara is rocky ground. But there are also places with grass, lakes,mountains, and even sand seas. A sand sea is just what it sounds like—it looks like a sea of sand! When the wind blows, the sand looks like waves.
Life in the Sahara is difficult. About two million people live in the Sahara. They usually move from place to place. There is water in a few parts of the Sahara, and some people live in these places all year round.
Not many animals can live in a place with such a dry and hot climate. They must adapt to survive. Camels, for example, go for a long time
without drinking water. When they do find water, they can drink more than 100 litres of it in 13 minutes! Fennec foxes live in the desert too. They have large ears to help their bodies stay cool.
Today, the world's largest hot desert is getting even bigger. It is now about 10 per cent larger than what it was about a century ago. But why is it growing Some scientists believe that part of the reason is climate change. As temperatures rise, summers in Africa grow hotter and less rain falls. Water bodies get smaller and the ground gets drier and drier. If we do not take effective measures to stop climate change, the desert will keep growing!

difficult; two million people live here and they usually move around.
It keeps growing and gets bigger because of climate change.
1. How is life in the desert different from other places where
people live
Discuss the questions.
Life in the desert is harder. There's less water, and people often move around, while in many other places, people have stable homes and enough water.
2.Would you like to visit the Sahara Desert or even live there for
a while Why or why not
I would like to visit the Sahara Desert because it looks very beautiful and special with its sand seas and rocks. However, I would not like to live there because life is too difficult, and there is not enough water.
3.What do you think will happen if the Sahara keeps getting
bigger What should we do about it
If the Sahara keeps getting bigger, more land will become desert, and it will be harder for plants, animals and people there. We should stop climate change by saving energy and planting more trees.(共8张PPT)
