The Sun sends huge amounts of energy to Earth.This solar energy
can be used to heat things,or to make electricity-without making
pollution.The Sun will still be shining long after the last coal
and oil have been mined.
The rows of solar panels on the roof of the house in the picture
turn the Sun's energy into electricity.This energy can be stored in
batteries.It can also travel along power lines into the electricity
system.
Solar water heaters absorb the Sun's energy to heat water.
This hot water is stored in a tank,which can be seen above the
two heating panels.
1.What does the sun send to Earth?
2.What can this solar energy be used for?
3.Does solar energy make pollution.
4.How long will the Sun be shining?
5.What is on the roof of the house in the picture?
6.What do the solar panels do?
7.How can the energy be stored?
8.What do solar water heaters do?
9.Where is the hot water stored?
10.Does your mansion/house have any solar panels?

Earthquake Rescuers
When the ground stops shaking after an earthquake,rescue workers
are quick to arrive.Sirens sound and helicopters hover overhead.
Rescuers search buildings and dig through the rubble.They listen
everywhere for sounds of life.They must work quickly to find
trapped survivors on or buried under the ground.
Earthquakes often destroy roads.Helicopters provide the only
means of carrying injured survivors to hospital.
Rescuers have a difficult and dangerous job.Cut power lines can
cause fires and broken gas pipes can release deadly fumes.The
mixture of gas and fires often causes sudden explosions.

Venezuela
Venezuela was one of three countries that emerged from the collapse of Gran Colombia in 1830 (the others being Ecuador and New Granada, which became Colombia). For most of the first half of the 20th century, Venezuela was ruled by generally benevolent military strongmen, who promoted the oil industry and allowed for some social reforms. Democratically elected governments have held sway since 1959. Hugo CHAVEZ, president since 1999, has promoted a controversial policy of "democratic socialism," which purports to alleviate social ills while at the same time attacking globalization and undermining regional stability. Current concerns include: a weakening of democratic institutions, political polarization, a politicized military, drug-related violence along the Colombian border, increasing internal drug consumption, overdependence on the petroleum industry with its price fluctuations, and irresponsible mining operations that are endangering the rain forest and indigenous peoples.

* The Saxons were named after a type of sword they used called a 'Sax'.
* The Saxons originally lived in Europe. Some of them came to live in Britain during the Dark Ages.

* The part of Britain which the Anglo-Saxons took over was named 'England' after them. It means 'Land of the Angles'.
* They all spoke a language similar to English. It is usually called 'Old English'. They used a type of writing called Runes for name tags and gravestones.
* Strictly speaking, the Saxons came from North-West Germany. Some of them moved south to set up Upper Saxony. The Angles came from Angeln in South-West Denmark. A third group, called the Jutes, came from Jutland in Central Denmark.
* Tradition says that the Saxons settled in Southern England; the Angles settled in East Anglia, the Midlands and Northern England; the Jutes settled in Kent, Hampshire & on the Isle of Wight.
* Other groups who settled in Britain can also be called 'Saxons'. These include the Frisians, the Franks and the Swabians.

Castles
Castles:
Since the power and security of a lord depended upon his ability to defend himself, fief owners began to build sturdy castles. Castles were designed to withstand a siege and to mount a defense.
At first castles were made of wood. But they were too easy to burn down. By 1100 CE, castles were built of stone. Thick walls surrounded a castle. Inside these thick walls, there were many buildings.

Rock Climbing
People of all ages enjoy the challemge of climbing on large rocks and up steep cliff faces. Rock climbers wear specially designed shoes and light clothing. Climbers also wear harnesses, which are devices that are strapped around the body. Ropes attached to the harness are anchored to rocks. The harnesses and ropes keep climbers safe if they fall. Rock climbers often work in pairs. As one person climbs,another on the ground pulls on the rope to make sure it is not too loose. People who climb on icy cliffs or glaciers use ice axes to cut holes in the ice where their feet can go.
