Perfect Squares Cannot End In Some Digits; Why?

Hi to everyone.

I am glad to announce that I am going to put an A++ mark on your end-course Maths qualification if you find an integer verifying to be a perfect square ending in "7".

If not... ...I will have enough if it finishes in "8" instead of "7"!

Still no luck? well, perhaps you should try with "2" or "3"!.

By the way... ...Why am I so sure that none of you are going to be able to find perfect squares ending with 2, 3, 7 or 8?

 (Of course, it's impossible, if you don't believe me, just keep on searching... ...and get bored!  ;D)

If someone explains it fine...  ...I will consider for a good mark. (This time is no joke).
Send me an e-mail before posting anything. If someone posts a right answer directly, following ones won't have the opportunity to do the same.

Good luck and think a bit.

RAFA.

ENERGY RESOURCES


Most of the ENERGY around us originates from the SUN. The Sun´s energy reaches Earth and is converted into many forms which we then use to supply our energy demands.

Many things around us require energy in order to function. TV set and stereo, microwave oven and electric kettle, computer and refrigerator - all of them need energy to work. Besides, energy is also necessary to make a car run, to keep the house warm or to heat water for showers.

Energy is produced or generated from natural resources, which are usually called energy sources. The examples of energy sources are gas, oil, water, sun and wind. However, not all energy sources are created equal. Some of them can be dangerous for the environment we live in.

That is why people decided to find other sources of energy, which would not harm the air and the amount of which would never end. Such types of energy sources are called alternative. All of these sources give us “clean” energy, because it is safe for people and for the environment we live in.

Read about alternative energy sources HERE.

EXERCISES:
1.- Write the names of all the types of alternative energy.
2.- Write something that surprised you.
3.- Choose one type of energy and write a short summary about its uses, pros and cos.
4.- Now you can test your knowledge about renewable and nonrenewable energy sources with this GAME. What was your score?

Medieval Castles

Hello boys and girls.

In a few days we are going to visit the castle of Almodovar, a town 22 kilometres far from Cordoba.



Castles were not just buildings, they were fortresses made to protect people during military conflict. As a result, most castles shared some basic parts that helped them serve their purpose.
Castles looked cool on the outside, but really they were cold, damp, and poorly lit. The only heating was provided by fireplaces in each room and castles had to be lit by torches because they were very dark inside.
Many different people lived in and around a castle. The lord and lady, of course, were there, but one could also find everybody from knights to cooks in and around the castle grounds:
  • The most important people, were the Lord, the lady and the Bishop.
  • We could find a lot of different people in castles:
Atilliator
Skilled castles worker who made crossbows.
Butler
Cared for the cellar and was in charge of wine and beer.
Castilian
Resident owner or person in charge of a castle.
Chaplain
Provided spiritual welfare for laborers and the castle garrison. The duties might also include supervising building operations, clerk, and keeping accounts. He also tended to the chapel.
Cook

Roasted, broiled, and baked food in the fireplaces and ovens

Knight
A professional soldier.
Messengers
Servants of the lord who carried receipts, letters, and commodities.
Squire
Attained at the age of 14 while training as a knight. He would be assigned to a knight to carry and care for the weapons and horse.
Watchman
An official at the castle responsible for security.

Answer these questions:
  • See this page and tell me what are the most important parts of a castle.
  • Investigate information about the Castle of Almodovar: 
    • Which is its origin?
    • When is the restoration that we can see now? Who promoted it?
    • How did the arabs call this place? 
See you in class!

"It's raining cats and dogs"

An idiom is a phrase that has a meaning different from the meaning of the individual words. For example: it's raining cats and dogs. This phrase has nothing to do with cats and dogs. It simply means that it is raining very heavily.
Idioms play a very important part in English. Native speakers often use them, so it's essential for you to learn some of them too.




1. Choose one idiom or expression that you like and write a sentence using it properly. You'll have to explain its meaning to your classmates using your own words. End date: Friday 10th February.

2. Some English idioms have an equivalent in Spanish. Can you find any?

 
3. Enjoy yourself learning idioms.
