They can live in different environments such as water, soil, air or inside other living things. Bacteria are the smallest living things. Most of them are so small that they can only be seen with a microscope. These bacteria are called micro-organisms or microbes. They often feed on decaying matter, such as dead animals or plants. Some bacteria are helpful: for example, they help us to make food. Milk is fermented with special types of bacteria to make cheese. ‘Good’ bacteria are also used to make yoghurt and bread. They give a unique texture and taste to the food. Other bacteria are harmful and can make you ill. Some diseases, such as measles and mumps, are caused by ‘bad’ bacteria. Bacteria can cause food to decay. If you eat mouldy bread, you can have stomach problems. Bacteria also cause tooth decay. We can protect ourselves from harmful bacteria by washing our hands, cleaning our teeth, and storing food carefully. We should also be careful how we cook our food. The bacteria which cause the disease salmonella can be killed by careful cooking. Bacteria en yoghurt

The olive tree ◆ The olive is an evergreen tree which can live for a very long time. It grows in dry, rocky places and is common in Mediterranean countries. The trunk of the olive tree is thick and twisted. Its bark is silver-grey in colour. Its leaves are narrow and pointed. They are dark green and smooth on top. The flowers of the olive tree are cream coloured and each flower has four petals and four short stamens. The fruit of the olive is like a berry. At first, it is green and then it ripens and becomes black. The fruit has a single brown seed inside. The olive tree has been cultivated since Antiquity. Olives are used to produce olive oil and are also eaten as a snack or in salads.

20,000 Leagues Under the Sea ◆ Jules Verne (1828-1905) was a French writer who wrote about fantastic adventures. In his book 20,000 Leagues Under the Sea, he imagines an enormous submarine which travels round the world. One of the people on the submarine – Doctor Aronnax – is a famous scientist. His servant Conseil loves classifying all the animals and plants under the sea. One day, the Doctor and Conseil are walking along the sea bed: Conseil: Look, Doctor! White coral and sea anemones – members of the cnidarian group of invertebrates! Aronnax: I’m sure you’re right, Conseil. But there’s something different over there – it’s an enormous, long worm! Conseil: Yes, Doctor, there are different worms. That one is a sea worm and then there’s the – Aronnax: How beautiful those starfish are! Can you see them? Conseil: Oh, yes. They belong to the echinoderms. Be careful, don’t put your hand on that! It’s in the same group as the starfish, but it’s covered with spines! Aronnax: Ouch! Too late… Conseil: Sorry, Doctor. Hey, look over here. Our eight-legged friend, of the mollusc group, the same as clams and snails… Aronnax: And lobsters, like this one here… Conseil: No, sir, this lobster is an arthropod. Do you see its hard exoskeleton? Aronnax: So we can’t see arthropods on land. Conseil: Oh, yes we can! There are many types of arthropod: insects, centipedes, arachnids… Aronnax: I think you’re a better scientist than me, Conseil!

4 Vertebrates

EXTENSION

Animals at play ◆ It is hard to imagine an ant or a worm playing. On the other hand, children and young animals, such as puppies and kittens, often play. In fact, most young mammals spend a lot of time playing. Young chimpanzees chase each other around, young badgers roll around on the ground, and ducklings splash about in the water. Mammals use their intelligence and learn from experience. Children who do not play when they are very young develop more slowly than children who play. Why do animals play? There are many theories. Play makes muscles strong and develops coordination. We can see this when chimpanzees jump from tree to tree and swing from branches. Play is also important for survival. In the wild, carnivores such as lions, must learn how to hunt in order to survive. In their games, the young cubs ‘fight’ and jump on each other. This is practice for when they must catch their prey in order to eat. We can see this type of behaviour in kittens when they play with a ball of wool: they sometimes jump on it and shake it as if it were a mouse. Herbivores, such as zebras, must learn about danger when they are young in order to survive. In their games, they spend time running after each other; this is practice for when a carnivore is trying to catch them. Play is also important in establishing communication. ‘Sociable’ mammals such as humans and chimpanzees play in order to decide who is more important in the group and who is less important. When two puppies play, they give out ‘signals’ to show that they want to play and not to fight. For example, they put the front part of their body on the floor and wag their tails.

5 Nutrition

EXTENSION

The heart ◆ Our heart plays an important part in our circulatory system. It works like a pump and moves blood through the body. It never stops beating. When you are resting, your heart beats between 60 and 80 times every minute. When you do exercise, or if you are very anxious, the number of heartbeats can increase up to 200 a minute. The heart is a muscle and, like all muscles, it needs exercise to keep it healthy. That is why it is important to be active and play sports. We also need to eat the right foods to keep our heart in good condition. Substances such as alcohol and tobacco can damage our hearts. The heart is divided into two parts, left and right. In pulmonary circulation, blood leaves the heart and goes to the lungs. In the lungs, the blood absorbs oxygen and releases carbon dioxide. Then the blood goes back to the heart through the pulmonary veins. In systemic circulation, blood with oxygen from the lungs leaves the heart through the aorta. This blood provides the body with nutritive substances and oxygen. Finally, it returns to the heart through the vena cava. We cannot live without a heart. In the past, people with very unhealthy hearts died. Then, in 1967, Doctor Christiaan Barnard carried out the first human heart transplant. In this operation, the healthy heart of someone who has died replaces the unhealthy heart of another person. Since then, thousands of heart transplants have been carried out. The first transplant patients did not live for very long, but techniques and drugs improved and today transplant patients are living for much longer.

Salt ◆ Salt is the common name for sodium chloride. Salt takes the form of transparent cubic crystals. It is most familiar to us as a food supplement, but it has many other uses. For example, salt is used in the chemical industry as a source of chlorine. (Chlorine is a green, gaseous element which you can sometimes smell in the water of a swimming pool.) Salt is also used for removing snow and ice from roads, softening water, preserving food and stabilising soil for construction. Salt is obtained from two sources: rock salt and brine. Rock salt is crystallised salt. It is the result of the evaporation of ancient oceans millions of years ago. Sometimes, pressure from inside the Earth forces up large amounts of rock salt to form salt domes. Brine is water that contains a high concentration of salt. It comes mainly from the sea. Salt is obtained when the water evaporates. The simplest form of evaporation is solar evaporation. This can only take place in hot, dry, sunny places. The brine is collected into shallow ponds and allowed to evaporate in the Sun. The salt which remains is washed and made into huge piles. The piles are left to drain for two or three months. Salt forms an important part of our diet. Salt for human consumption must be very pure.

7 The atmosphere

EXTENSION

Clouds ◆ Clouds are made up of millions of tiny water droplets. The droplets form when water vapour rises into the atmosphere and cools down. If the cloud is extremely cold, it is made up of ice crystals. In 1803, a man called Luke Howard invented a way of classifying clouds. He used Latin words to describe their characteristics, for example: • cirrus means a filament or tuft (like a piece of hair) • cumulus means a heap or pile • stratus means a layer • nimbus means carrying rain Today, we usually refer to ten basic types of cloud. We use combinations of the four words above to describe them. We can divide the ten types of cloud into three sections: low clouds, medium clouds and high clouds. • Low clouds have their base below 200 metres from the ground. They are usually made up of water droplets. • Medium clouds have their base between 2,000 and 7,000 metres. They are mainly water but they can contain ice crystals. • High clouds have their base between 5,500 and 14,000 metres. They are normally made up of ice crystals. In our Solar System, any planet or moon with an atmosphere also has clouds. Venus’s clouds are made up of sulphuric acid droplets. Mars has high, thin clouds of water ice.

The Amazon is the largest river in terms of its watershed, the number of tributaries (over 200), and the volume of water which it discharges into the sea. The Amazon basin is huge: it covers more than 7,050,000 square kilometres. The mouth of the Amazon is so wide and deep that large, ocean-going ships have navigated its waters and have travelled as far as two-thirds of the way up the river. In the flood season, the Amazon widens and covers its banks and the islands in the middle of the river. The sediment left by the floods enriches the soil. There are no bridges across the Amazon because it flows mostly through tropical rainforest where there are few roads and cities. The tropical rainforests are home to more than a third of all the species in the world. It is home to wonderful animals such as the jaguar, the largest cat outside of Africa and Asia, and the anaconda, an enormous, heavy snake. The rainforests are in danger from overexploitation and pollution.

EXTENSION

Tourism in Spain ◆ The tourist industry in Spain is very important. It provides a lot of jobs in the service sector – in hotels, restaurants and bars. It also creates work in the area of transport. Most tourists visit Spain’s coasts. They come to relax on the beaches in the Sun. Some tourists travel inland to the mountains or visit cities such as Barcelona or Salamanca. Many tourists come from abroad, but Spanish people also take holidays in their own country. A good transport system is essential for successful tourism. In Spain, there are airports in most of the major cities and good rail and road systems. In the cities, there is quick, inexpensive underground transport. A lot of people depend on tourism for employment. Today, there is competition from other countries which want to attract tourism. Some of these countries are cheaper than Spain and some are less exploited – they have not yet built too many holiday resorts. Some Spanish resorts are half-empty in the winter months, so income from tourism decreases. The decline of agriculture in Spain is also partly connected with tourism. Land previously used in agriculture has been used for building tourist apartments and hotels. This could be a bad thing. If tourist numbers fall, many apartments will stay empty and it will be too late to use the land for agriculture.

12 Prehistory and Antiquity

EXTENSION

Digging up the past ◆ Eva is a student. Last summer, she spent part of her summer holidays working on a ‘dig’ (or archaeological excavation). Her favourite subject is History and she loves finding things which bring the past to life. The site where Eva worked last summer is near Alicante. The government had started to build a new road. Then, one of the excavating machines uncovered some old stones. These stones were ruins which belonged to a very old building. The government stopped building the road and put up a fence to protect the area. Archaeologists came with helpers such as Eva. Carefully, they began to take away the earth and slowly the remains of ancient civilisations began to emerge. ‘It’s very interesting,’ says Eva. ‘The first layer looks like the remains of a Roman villa or bath house. But under that, we found objects from earlier periods. There are fish hooks and other tools. They are probably from the Phoenician or Carthaginian civilisations. We also found some pots and jewellery which are definitely from Iberian times: some of the decoration is like that on the Lady of Elche. I hope the government doesn’t start building the road again. This is a very important site. It can teach us a lot about the people who lived here before us and their way of life. Who knows?

13 The Middle Ages

EXTENSION

Thomas Aquinas ◆ Thomas Aquinas was born in his father’s castle in Italy in 1227. His father was Count Landulf, an important nobleman. When he was five years old, Thomas began his education at a monastery. At that time, monasteries were important centres of learning and knowledge. They had schools and libraries. This was before the age of printed books (the printing press was invented in about 1450) so the books which Thomas studied were made by hand. The scribes copied manuscripts onto parchment and decorated them with illustrations and very thin layers of gold. Thomas was an intelligent student and was always asking questions. In 1244, he went to study in Cologne in Germany. After that, he continued his studies at the University in Paris. Classes there consisted of reading and explaining texts. Examinations were oral. Thomas eventually became a university professor. He taught theology in different European cities. He worked very hard and spent a lot of time travelling. On one of his journeys, he became ill. He was taken to a monastery in Italy where he died in 1274. Thomas was a great philosopher and theologian. He wrote many important works. He tried to explain his ideas clearly and simply. In 1323, Pope John XXII made Thomas a saint of the Catholic Church. Today, the Roman Catholic Church celebrates the feast of Saint Thomas Aquinas on January 28th. This is the publication date of his most famous work, Summa Theologica.

The salt is separated from the water by the process of evaporation. In hot countries, the Sun is used in this process. The brine is usually collected from the sea. It is left in small, shallow ponds for a period of time. The Sun acts on the brine and evaporation takes place. The water gradually disappears and soon only the salt remains. This salt contains some impurities, and it must be washed several times. The salt is made into piles which dry in the Sun for two to three months. Some salt is used in food, and other types of salt are used, for example, in the chemical industry.
