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, the desert will keep growing!

Discuss the questions.
2
1. How is life in the desert different from other places where people live
It’s very dry and hot, so water and food are hard to find.
People often move around instead of staying in one place.
Only a few people live near water, and life is much harder.
2. Would you like to visit the Sahara Desert or even live there for a while
Why or why not
I’d love to visit to see the beautiful sand seas and stars. But I wouldn’t want to live there, because the hot, dry weather and lack of water would make daily life too difficult.
3. What do you think will happen if the Sahara keeps getting bigger
What should we do about it
What will happen: More land will become too dry for farming, people will lose homes and water, and wildlife will be in danger.
What to do: We should fight climate change, save water, and plant more trees to stop the desert from growing.
Reflecting
1. What new facts about natural wonders have you learnt
2. Can you make comparisons when talking about natural wonders
3. Can you use large numbers to give some geography facts
4. Can you explain how and why people connect with nature
5. What are some achievements that people have made while exploring nature
Nature makes us wonder. That is why it is wonderful.
Homework
Write a short reflection(50 words) about your learning in this unit(e.g.，“I learned about Mount Qomolangma and how to use superlatives. I like the poster project because it's fun.”).
