Broken bonesBones are hard, strong and rigid, but they can sometimes break orfracture. However, broken bones can repair themselves.

There are many different types of fractures. The most common typeis a simple fracture, which happens when a bone breaks cleanly.

In order to help bones heal correctly, it is important that they arerealigned. Broken bones can be put back into position by a doctor.The bones are then immobilised with a plaster cast, so they canstart to heal. Simple fractures usually take about 6 to 8 weeks to

heal, although large bones take longer.

The Venus flytrapThe Venus flytrap is a small, carnivorous plant. Its sweet-scented leaves attract insects.These leaves open and close like jaws to capture insects. When the plant is touched,sensitive hairs on the inside of the leaves sendsignals to the plant. So, when an insect touchesone of these hairs, the leaves snap shut. Theplant then slowly digests the trapped insect. Afterabout a week, all that is left of the insect is its hardexoskeleton.

The Venus flytrap can live in soils with a lowmineral content because it obtains minerals fromthe insects it captures.

Read and write True or False . Correct the false sentences.

a. The Venus flytrap is a meat-eating plant.

b. The plant’s beautiful flowers attract insects.

c. Sensitive hairs digest the trapped insect.

Water, precious water About three quarters of our planet’s surface is covered withwater. However, most of this water is salt water. Just avery small amount of water is fresh water. Most of thisfresh water is trapped in ice caps and glaciers. It isalso found in rivers, lakes and as groundwater.This means, there is very little water available forpeople to use.

The world’s population has increased dramatically,and water consumption today is seven times higherthan a hundred years ago. We need to save water andkeep it free from pollution and contamination.

Landscapes7

Sculpted landscapesWind and water have shaped landscapes all over the Earth.No rock is hard enough to resist the forces of erosion.

Wind is a powerful force that carries dust and sand fromone place to another. It can carry huge amounts of dust oververy long distances. It can also blow sand against rocks withtremendous force. This causes soft rocks to slowly wear downand sculpt amazing formations like arches, buttes and dunes.

Moving water in rushing streams and rivers is the major agent

of water erosion. Ocean water changes the shape of coastlines.Waves constantly crash against cliffs forming arches, caves and columns.Rain slowly washes away soil and rock fragments creating ever-changinglandscapes.

Match the rock formations to their definitions.

a. cave a vertical rock formation

b. arch a hill that rises sharply and has a flat topc. butte an underground hollow with an opening to the outside

d. dune a curved rock formation

e. column a hill of sand


a. All rocks on Earth wear down over time.

b. Wind is the major agent of erosion.

c. Buttes are rock formations of coastal landscapes.

Weather satellitesNowadays, weather satellites collect completeweather information about every place on Earth.They provide satellite images and other usefuldata about the atmosphere.

There are two types of weather satellites: polarorbiting and geostationary. Polar orbitingsatellites go around the planet from the NorthPole to the South Pole, and are able to view

every part of the Earth twice a day! They travel close to the Earth’s surface, as lowas 800 km, and provide extremely detailed satellite pictures of weather patterns aroundthe planet. Geostationary satellites track the weather over one specific region by stayingover the same place. They orbit the planet at 36,000 km above the Equator.

Weather satellites collect more than just information about the weather. They can also tellus about forest fires, volcanoes, dust storms and other environmental phenomena.

Villages, towns and cities over timeMany villages, towns and cities in Spain arethousands of years old and they have changedcompletely since their origins.

Over a period of hundreds of years, some smallvillages grew into towns and some of the townsbecame big cities with large populations, tall buildings,wide streets and many industries and services.

Three quarters of the population of Spain now lives in towns and cities. However, only two

cities, Madrid and Barcelona, have a population of more than one million inhabitants, andonly four other cities, Valencia, Seville, Zaragoza and Malaga, have a population of over500,000 inhabitants.

However, not all villages have grown. Some are almost abandoned these days, with fewinhabitants left, due to rural migration. The villagers have moved away to the cities insearch of jobs, education and better opportunities.

Where does paper come from?Paper was invented in China over 2,000 years ago.Originally, paper was made of pulp produced byboiling cloth and old fishing nets!

Nowadays, paper is made of pulp from wood. Largeplantations of trees are grown. The trees are cut down,then chopped into small wood chips. These chips aresoaked in water and chemicals to form wood pulp.The pulp is bleached to remove tree bark and sap.

Next, the pulp is drained and squeezed to remove all the excess water, then placed in hugedrying machines. The pulp is then attached to spools and placed in cutting machines.

Lots of different paper products are made these days from recycled paper. Usingrecycled paper to make new paper has a less negative impact on the environment,and is better for the planet.

Recycled paper is used for everything from paper plates to toilet paper!

The Dead Sea is really a salt lake.It is located in the Middle East,between Jordan and Israel. It iscalled a ‘sea’ because the wateris so salty. And it is called ‘dead’because fish and plants cannot livein it due to its high salt and mineralcontent.

The Dead Sea is 420 metres below

sea level, and it is considered thelowest point on the planet. In fact,its salt content is due to its location.Being the lowest point on Earth,minerals have been flowing into itfor millions of years, making the Dead Sea nearly nine times saltier than the oceans.This high concentration of salt allows people to float in it without using a life jacket.
