Dinosaurs
Dinosaurs lived on earth for more than 150 million years. By studying fossils, scientists have worked out that dinosaurs died out about 65 million years ago. The fossils show that there were more than 700 kinds of dinosaurs. We also know that some of today’s animals come from dinosaurs, such as lizards and birds.
  Why did dinosaurs disappear? Scientists have suggested different ideas, for example, the weather became too hot or too cold, or the dinosaurs caught a terrible disease and died out. There are now some other theories. One theory is that there was a huge meteorite which hit the earth, or perhaps there were a lot of volcanoes.
  What would have happened if a huge meteorite had hit the earth? There would have been a lot of smoke and dust. What would have happened if a lot of volcanoes had erupted at the same time? There would have been lots of dust and gas in the atmosphere. Both these events would have stopped the sun shining on the earth for many years. The dinosaurs would have disappeared very quickly.
  Some scientists think that the dinosaurs disappeared slowly. The earth was changing and some areas became cooler and drier. Perhaps the dinosaurs could not get the food that they needed. If scientists had been on earth 65 million years ago, they would have seen why the dinosaurs disappeared.

Tapescript

Female guide: Welcome to the history museum. Have you all seen the dinosaurs? Yes?
Children: Yes
Female guide: Good. Now many people ask me, “Did dinosaurs live at the same time as people?” The answer is no! Dinosaurs lived approximately 65 million years ago. Scientists are not sure exactly when people started living on earth. We think that people first lived maybe 250,000 years ago. Today I’m going to talk to you about some people who lived about 8,000 years ago. One of the most important times in history was when people learned to make things with stone. Then they were better at catching animals and could build better homes. This was called the Stone Age. At the beginning of the Stone Age, people moved from place to place. They did this because they needed to look for food.
Girl 1: Where did they live?
Female guide: That’s a good question. There weren’t any houses then. They lived in caves. Archaeologists have found cave art in different places round the world.
Girl 2: What did they eat?
Female guide: They ate plants and also meat from the animals they caught.
Girl 3: How did they keep warm?
Female guide: They learnt to make fire. Then, in around 8,000 BCE, people began farming in North Africa. They planted wheat and they kept sheep. They began to build huts to live in so they wouldn’t have to move around. What else do we know about this time? Well, archaeologists have found animal bones which people used to sew clothes. We know that people used animal skins to make their clothes. These kept them warm.
It was perhaps 4,000 BCE when people started making pots and pans out of clay. This meant they could eat different food, like soup.
Girl 4: Did they have cans of soup?
Female guide: No! People couldn’t eat soup in cans until some time in the nineteenth century. You can see that life was very different from today






Tapescript (2)
Narrator 1: One
Narrator 2: Hippos can walk and run very fast, but they can’t swim. When they move quickly through water, they are walking or pushing themselves off other objects. So the answer is a.

Narrator 1: Four
Narrator 2: Zebras can run up to 65 kilometers an hour, so it is very difficult for other animals to catch them. So the answer is c.
Narrator 1: Five
Narrator 2: Crocodiles often wait by rivers with their mouths open when they are hot. It helps them to be cooler. So the answer is a.
