Remember Light travels in all directions at very high speed and in a straight line. There are three different types of objects according to how much light passes through them: opaque, translucent and transparent. When light reaches an opaque object, it bounces off the object into our eyes so we can see it. This is called reflection. When light reaches a transparent medium, it bends and changes direction. This is called refraction.

Under the sea

Name

Life under the sea is very different from on land. It is difficult for people to see, hear and move well under water. Unlike fish, people cannot obtain oxygen directly from water. Instead, they need to carry oxygen tanks with them. People need to be healthy and in good shape to stay underwater for a long time. Their hearts, ears and lungs must be strong, since these are the organs that suffer the most underwater. People need special equipment for underwater diving such as a diving mask, fins, a wetsuit, a weight belt, a compressed air cylinder and some goggles.

Long live the hamburger!

Name

EXTENSION

Date

Did you think hamburgers were a modern food? Believe it or not, the origin of the hamburger goes all the way back to ancient Egypt -- more than four thousand years ago! Much later, the soldiers of Genghis Khan, a Mongol emperor in the 13th century, ate steaks of minced beef. They took this recipe with them to Russia. Russians eat a variation called ’tartar steak’: raw, minced meat mixed with many spices. The name «hamburger» comes from the German city of Hamburg, where it was very popular in the 14th century. This is when the hamburger began to look like the ones we see today: a flat cake of minced beef placed between two slices of bread. The hamburger arrived in Britain in the 19th century. After that, the British introduced this food to the U.S.A. Nowadays, the hamburger is one of the most popular meals in the world.

Answer the questions. Who made the first hamburgers? How many years ago?  Who was Genghis Khan?  Where does the name ‘hamburger’ come from?  What were hamburgers like in the 14th century?  What country introduced hamburgers to the United States?

For thousands of years, people have used plants for food, wood, clothes, dyes, and medicines. For example, hundreds of years ago, native American Indians used the bark of the willow tree to relieve pain. Nowadays, a substance is taken from the bark of this tree to make the well-known medicine called aspirin. There are many other examples of medicinal plants, however, not many of them are used nowadays because most medicines are made artificially in laboratories. However, you can still find natural medicines in people’s homes. These include teas, eucalyptus, thyme, tilia, rosemary, nettle, chamomile and valerian. 1

Fossils: rocks that reveal the past

Name

EXTENSION

Date

We can sometimes find fossils in rocks. They are the preserved remains of plants and animals that lived on Earth millions of years ago. Palaeontologists are scientists who study fossils because they can give us information about climate and the environment in the past. For example, if you find the remains of marine animals in rocks, then this area was probably under the sea thousands of years ago. Fossils can be plant remains, or remains of animal bones, skeletons or teeth. Special fossils called ‘ichnites’ are rocks with dinosaur footprints. These fossils can be found in various parts of Spain, in the Autonomous Community of Rioja, and in the provinces of Teruel and Soria.

National Parks are created in natural areas where one or more ecosystems are unspoilt by human activities. The plants and animals in these ecosystems are of special interest. In National Parks, special steps are taken to protect the landscape, flora and fauna. In 1872, the United States created the first National Park in the world: Yellowstone National Park. In Spain, the first National Park, Mount Covadonga, was created in 1918. It is now renamed the Picos de Europa National Park. At present, there are fourteen National Parks in Spain. They offer the best examples of Spain’s natural heritage: Aiguestortes and Estany of Sant Maurici, the Cabrera Archipelago, Cabañeros, Caldera de Taburiente, Doñana, Garajonay, the Atlantic Islands of Galicia, Monfragüe, Ordesa and Mount Perdido, Picos de Europa, Sierra Nevada, Tablas de Daimiel, Teide and Timanfaya. 1

Plastic: a modern material

Name

EXTENSION

Date

Plastic is an inexpensive and versatile material which is used to make many objects. For example, it is good for making containers because it is resistant to chemical changes. It is also a good insulator since it does not conduct electricity. There are different types of plastics, such as: Polystyrene, for making plastic bags. Expanded polystyrene (EPS), for packaging and containers. Bakelite, an insulating material for making pot handles. Rubber, for making car or bike tyres. Polyester, for making clothes. However, not everything about plastic is good. Plastic is not biodegradable. This means it remains in nature for several hundred years, polluting the environment. To reduce this pollution, people have started to recycle plastics instead of just throwing them in the rubbish bin.

Perpetual motion

Name

Date

All the machines we use need energy to function: a television needs electricity, a car needs petrol, a sailing boat needs wind, a bike needs a person to push the pedals. Throughout history, people have tried to invent a machine that, once it was started, would not need more energy to keep functioning. This type of machine is called a perpetual motion machine. Many people have tried to achieve fame by inventing a perpetual motion machine. However, all their machines eventually stopped because the energy ran out. If these inventions had worked, they would have changed the course of history. M. Escher: Waterfall (1961).

Shadows

Name

EXTENSION

Date

People have always been fascinated by shadows because, although they are always with us, we can never catch them or touch them. For this reason, shadows are often found in games and stories. Do you remember the story of Peter Pan losing his shadow? But what is a shadow? It is the dark area caused by an opaque object blocking light. It has the same shape as the opaque object. Shadows appear because light travels in a straight line and cannot go around obstacles. Shadows can gradually change shape. They get longer when the angle between the light source and the opaque object increases. They get shorter when the angle decreases. Try this experiment: darken a room by turning off all the lights and closing the curtains. Then, turn on a lamp or a torch and put your hands close to the light source. Move your hands farther away to see how their shadows change shape. 1

Answer. What is a shadow?   Why do shadows have the same shape as the opaque object?   Why do shadows gradually change their shape?

Geographical coordinates

Imagine you want to travel by ship to the Canary Islands. First, you need to locate these islands on a map. Then you need to find their cardinal points. The principal cardinal points are north, south, east and west. There are other points between these: northeast, northwest, southeast and southwest.

Greenwich Meridian Canary Islands Equator

Next, you need to know the exact location of the Canary islands on a globe. To do this, you use geographical coordinates. These are a set of imaginary horizontal and vertical lines that help to locate geographical locations. The horizontal lines are called parallels because they are parallel to the Equator. The vertical lines are called meridians and go from pole to pole. We use parallels and meridians to determine the latitude and longitude of a place. Latitude is the distance between any point and the Equator. Points to the north of the Equator are latitude north and points to the south are latitude south. Longitude is the distance between any point on Earth and the Greenwich Meridian. Greenwich is a town in the United Kingdom. Points to the east of Greenwich are longitude east and points to the west are longitude west.

Day 2 From the park we continue through Ledesma until we reach the city of Salamanca, where we can see the River Tormes. There are two cathedrals in Salamanca. The Old Cathedral was built in Romanesque style in the 12th century. The most spectacular part is the tower, which looks like it is decorated with stone scales.

Day 1 We enter the province of Salamanca at the city of Zamora, which is very close the border with Portugal. Here, we take a tour around the Arribes del Duero National Park. The River Duero flows through this deep canyon, which has vertical walls 162 kilometres long and up to 150 metres high.

Day 3 From Salamanca, we continue to the town of Bejar. Then we go on to Candelario, one of the coldest and most beautiful villages in the province of Salamanca. The River Cuerpo de Hombre flows through here.

The world’s population has grown rapidly in recent decades. In 1950, there were about 2,500 million people. Today, there are more than 6,500 million people. There has been a rise in births and a decline in deaths, making the population grow. Approximately 250 people are born and 100 people die every minute. This means that there are 150 more human beings every minute and 216,000 more every day! The main reason for this growth is improved living conditions. These include: technological advances in producing and preparing food, fewer diseases and improved control, better hygiene and medical research. The world’s population is not evenly distributed. Asia is the most inhabited continent: in 2005, there were 3,950 million people. The second most inhabited continent is America with 1,263 million people, followed by Africa with 925 million. Europe has 728 million people and Oceania has 33 million. The least populated continent is Antarctica, which is only populated by about 1,000 scientists from around the world.

The International Labour Organisation (ILO) is a specialised agency of the United Nations (UN) which promotes better working conditions for workers all over the world. It was founded after World War I, on 11th April, 1919. The ILO is made up of representatives from governments, trade unions and employers. The headquarters is in Geneva, Switzerland. One of the main aims of the ILO is to eradicate child labour. One in six children between the ages of five and seventeen works. This means approximately 211 million children around the world. Sixty percent of these children are in Asia, especially in a country called Bangladesh. In India, where there are at least 60 million children working, a trade union for children, called Bhima Sangha was created in 1990. The trade union helps child workers get together to defend their rights. In 1969, the ILO received the Nobel Peace Prize for its defence of workers rights.

Long live ‘La Pepa’!

EXTENSION

Name

Date

A country’s most important law is its Constitution because it defines the rights and obligations of its citizens. The first written constitution in history was drawn up in the United States, in 1787. Over the last two hundred years, Spain has had several Constitutions. Perhaps the most famous is the Constitution adopted in Cadiz on 19th March, 1812. It was known as ‘La Pepa’ because it was adopted on the day of San Jose. ‘La Pepa’ defined ideas that, although they seem very normal to us today, were very revolutionary in the 19th century, such as freedom of the press or the right to choose political representatives. Unfortunately, the Constitution of Cadiz did not last long because King Fernando VII prohibited it in 1814. He even made it illegal to name this Constitution. To get around this problem, supporters of the constitutional system used the expression Viva la Pepa! (Long live Pepa!) which really meant ‘Long live the Constitution!’

Read about the Spanish Constitution of 1978. Spain’s Constitution of 1978 took about one year to write and adopt. First, seven members were chosen to write the text of the Constitution. Then, a Constitutional Commission, made up of 36 people discussed and agreed on the text. Next, the Commission’s text went to Parliament, where the deputies and senators voted on all the articles of the Constitution. After that, the citizens of Spain approved the Constitution in a referendum held on 6th December, 1978. Finally, King Juan Carlos I signed the Constitution and it became law on 27th December, 1978.

Roman roads

Date

In Ancient Rome, there were roads that spread across the entire Roman Empire. They covered more than 90,000 miles and connected important cities and regions. The Romans first built roads for their armies. However, these roads soon became very important for trade and communication. The Romans built their roads using many layers of stone: First, they dug a deep trench and filled it with a thick layer of stones called the statumen. Then they laid down a layer of sand or gravel called the rudus. Next, they put a layer of crushed stones mixed with white lime on top. This was called the nucleus. Finally, they covered everything with paving stones called a pavimentum or summa cresta. 1

Answer. What did the Roman roads connect?   What were the Roman roads first built for?   What constructions nowadays are similar to Roman roads?

The 18th century was a crucial time in the search for more sources of energy. From prehistoric times and up till the 18th century, there had not been many changes, despite the increasing need for energy. At the end of the 18th century, James Watt, a Scottish inventor, invented the steam engine. This machine used the energy of water vapour that was collected from burning coal. Energy from water vapour could move a wheel at a steady rhythm. The steam engine was used in many different ways, in factories, in mines and for means of transport, especially trains. Thanks to James Watt’s steam engine and other great inventions, large factories were built which employed many workers. This period of history is called the Industrial Revolution. 1
