The scary skeleton

A curious cat

e-book DIDAPAGE

 Questo e.book è stato realizzato nell'ambito del progetto legalità. Attraverso l'annosa questione del bullismo e della violenza contro le masse, si ripercorre l'ideologia di tre grandi uomini storici che seppero dare la giusta risposta alla violenza, fenomeno che ancora oggi conosciamo. L'unica risposta ragionevole alla violenza è la non-violenza. Ragazzi, fete tesoro di queste lezioni di vita! La non-violenza non è intesa come passiva accettazione, bensì presa di consapevolezza della minaccia e nascita di una coscienza generale di masse. Solo uniti si vince.

What is DNA?

DNA is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix. The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of DNA is that it can replicate, or make copies of itself. Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.

VOCABULARY

Mitochondria are structures within cells that convert the energy from food into a form that cells can use.

Nucleotide: A nucleotide is an organic molecule made up of a nucleotide base, a five-carbon sugar (ribose or deoxyribose) and at least one phosphate group. Nucleotides make up the basic units of DNA and RNA molecules.

why do we have day and night?

WHY DO WE HAVE DAY AND NIGHT?

Why do we have day and night? 
We have day and night because the Earth rotates. It spins on its axis, which is an imaginary line passing through the North and South Poles.

How long does it take the Earth to turn around?  
The Earth takes a whole day (24 hours) to make a complete turn.

Why is the Sun in the sky at some times and not at other times? 
At any time half of the Earth faces the sun. This part has day. The other half of the Earth faces away from the Sun. It receives no light. It is dark and has night.

 
Why does the sun seem to move across the sky? 
The Sun does not move. It seems to move across the sky starting in the east in the morning, moving toward the south at noon, and then toward the west as the day ends. It is the Earth turning that makes it seem as though the Sun is moving.

Electricity

ELECTRICITY

Without electricity our lives would be darker and colder.
 Many appliances in our homes use mains electricity to work. We normally get electricity from the mains or batteries.
Small electrical appliances often use batteries which store electricity.( eg. Mobile phones, Mp3). These appliances can be moved place to place.Batteries run down and need to be replaced or recharged.
A complete circuit is when all the components are set up correctly to allow for electricity to flow. Electricity only flows when the circuit is complete with no gaps.
Conductors are materials that can carry electricity.Many materials conduct electricity, metals such as copper, steel, aluminium.

VOCABULARY

 Appliances are any term in your home which uses electricity.(TV, fridges, computers and many others).

BATTERY

Mains allow electricity to reach our homes.

A battery is the component which provides electrical power to a circuit.


A plug goes into a mains to provide power to an appliance.

The world wars and the new deal

THE WORLD WARS AND THE NEW DEAL 

At the first the USA did not take part in the First World War but then in 1917 it declared war on Germany. The USA sent a great number of soldiers to help the Allies (Britain, France and Russia), who won in the end.

After the rise of the Nazis in the 1930’s it became clear that Europe was moving towards another war. Americans wanted to avoid it at any cost. This feeling was intensified by the Great Depression in the 1930’s. In the years 1933-1937 President Franklin Delano Roosevelt promoted a set of economic and social policies to get out of the crisis, which was called the “New Deal”.

In 1939 the Second World War broke out in Europe. The USA remained neutral until 1941, when Japan attacked the American ships at Pearl Harbor. In 1945 the USA dropped two atomic bombs on Hiroshima and Nagasaki. Japan surrendered.

At the end of  the Second World War the USA was considered the leading world super power, and this position was even stronger after the fall of the Soviet Union in 1991.

Answer to the questions:

When did USA take part in the First World War?

What did become clear in Europe in 1930’s?

What was the Great Depression?

Who was Roosevelt and what did he do?

When did USA enter in the Second World War?

Where were two atomic bombs dropped?

JANE AUSTEN

Jane Austen

Jane Austen was born in 1775 at Steventon, Hampshire. Her family, that she was deeply attached to, belonged to the local gentry. Her mother came from an old family and her father was an educated clergyman; he possessed a rich library where Jane read lots of novels, histories, essays and sermons.

When the Austens moved to Bath, Jane was disappointed because she didn’t like that noisy town: so when her father died, she moved to Southampton together with her sisters. In a cottage at Chawton, she revised and published “Sense and Sensibility” and “Pride and Prejudice”(1813). There she also wrote her last novels.

 

“Sense and Sensibility” was written by Jane when she was 17. She read her novel to  her family that encouraged her to write. The two protagonists of the book, Elinor and Marianne, are two sisters standing for “sense” and “sensibility” respectively. Elinor is a self-controlled woman who waits for the man she loves and is involved in an impulsive engagement. On the contrary, the passionate Marianne learns at her expenses that brilliant young men are not always good husbands. She ends by getting married to an elder man whom she gets to a less passionate but more realistic happiness.

   

  “Pride and Prejudice”  

takes place at the beginning of the XIX century. Jane Austen, as usual, set in a small provincial district in the countryside.The characters belong to the rural gentry of the middle class; industrial towns and natural scenes as well as aristocracy and humble classes are excluded from Jane Austen’s works, as she wanted to deal with what she knew deeply. ‘Pride and Prejudice’  tells us the heart-warming story of getting the man of your dreams – and all the troubles that are connected with it. The Bennett family are living a calm and quiet life in Longbourn.  Mr. Bingley, a young man of good fortune, is going to become their neighbour. What a chance for silly Mrs. Bennett to get one of her five daughters married! With the arrival of Mr. Bingley, Mr. Darcy, and, later in the story, clergyman Mr. Collins and Officer Mr. Wickham, Mrs. Bennett tries her best to get those men’s attention for her daughters. The story is told by a third person narrator, who describes the physical appearance and the thoughts of her characters, and judges them adding a didactic purpose as well.
