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.

Remember
White light is made up of all the colours we can see.
The primary colours of light are red, green and blue. When we mix the primary
colours of light we can create all the colours of light.
When light rays reach an object, this object absorbs some of the light and reflects
some of it. The colour we see is the colour of the light that the object reflects.

Where does the name ‘hamburger’ come from?

What were hamburgers like in the 14th
century?

What country introduced hamburgers to the United States?

1
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.

Where have ichnites been found in Spain?

1
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

Write a short summary of the text.

1
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.

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.

Answer.
What is a shadow?

Why do shadows have the same shape as the opaque object?

Why do shadows gradually change their shape?

1
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.
189714 _ 0051-0081.indd 66 11/07/11 13:50

Match each shadow to the correct pair of hands. Then, practise the shapes.
Look at where the Sun is and where Peter Pan is standing. Draw his shadow.

What are geographical coordinates?

What are meridians?

What is latitude?

1
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.
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.

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 most inhabited countries in 2005 were:

What is the ILO?

When was it founded?
Where is its headquarters?
What are the aims of the ILO?

1
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.

Where was the first Constitution
in history written?
In Spain.
In the United States.
In what century was ‘La Pepa’
adopted?
In the 18th century.
In the 19th century.
What does a constitution define?
The rights and obligations of its citizens.
The country’s holidays.
1
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!’
Long live ‘La Pepa’!13
Where was Spain’s first Constitution
adopted?
In Cadiz.
In Madrid.
Which King prohibited the Constitution
of Cadiz?
Felipe II.
Fernando VII.
How long did the 1812 Constitution last?

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.

What did the Roman roads connect?

What were the Roman roads first built for?

What constructions nowadays are similar to Roman roads?

1
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.

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.
