INTRODUZIONE Il testo GET AHEAD è un valido e completo strumento per la preparazione alle prove INVALSI e al nuovo Esame di Stato; si caratterizza per una serie di percorsi CLIL di Scienze, Tecnologia, Arte, Geografia, Storia, Letteratura, Cittadinanza, Musica, Educazione Motoria.

Il materiale proposto rappresenta un nuovo approccio allo studio delle discipline e mira a consolidare e potenziare le competenze attraverso l’uso della lingua inglese.

Ogni unità è dedicata a una materia ed è sviluppata in 3 macro argomenti che, oltre ai contenuti, offrono esercizi di listening e reading per l’esercitazione INVALSI, e di comprensione e produzione per l’Esame di Stato.

Le varie sezioni sono contrassegnate da etichette: INVALSI READING, INVALSI LISTENING, ESAME DI STATO e indicano esercizi validi per l’una o l’altra prova.

Al termine di ogni unit, le pagine dedicate alla presentazione orale delle tematiche trattate e/o alla revisione degli argomenti (ORAL PRESENTATION – LET’S RECAP) sono un valido aiuto per il ripasso; alcuni argomenti infatti potrebbero risultare difficili da riferire, avendo come base il livello linguistico A2 richiesto alla fine della Scuola Secondaria di I Grado. Pertanto, in questa ultima parte, le mappe concettuali fungeranno da “bussola” per il colloquio pluridisciplinare e aiuteranno gli studenti nell’argomentazione e nella risoluzione di problemi, oltre a sviluppare il loro pensiero critico e riflessivo. Inoltre, ai fini dell’inclusività, saranno un ottimo sistema per facilitare la comprensione dei contenuti.

Per la parte relativa agli ascolti INVALSI, tutte le tracce degli ascolti sono disponibili on line, al link www.raffaellodigitale.it/geah Allo stesso link è possibile esercitarsi per la prova computer based – CBT. Non rimane altro che augurare a docenti e studenti un buon lavoro, prendendo a prestito le parole di Benjamin Franklin: “Tell me and I forget, teach me and I may remember, involve me and I learn”.

SCIENCE

Miss Mitchell’s Comet Maria Mitchell was born in 1818 in Nantucket, Massachusetts.

Her father, William Mitchell, owned a small telescope. Thanks to it, William and his daughter conducted observations which helped the young girl become fascinated with astronomy and physics. When she was 12, Maria helped her father when he calculated the moment of a solar eclipse! On the night of 1st October 1847, Maria went to the roof of the bank where William worked. There, she began observing the skies and to her great surprise, she discovered a comet, invisible to the naked eye.

On 3rd October, her father wrote a letter to Cambridge University informing this institution about his daughter’s discovery, which was designated as C/1847 T1, but commonly known as “Miss Mitchell’s Comet”. In 1848 she became the first female member elected for both the American Academy of Arts and Sciences and the American Association for the Advancement of Science. In 1849 she became one of the first female members of the American Philosophical Society.

In 1865 she was the first professor at the new Vasser College, as well as the director of the college observatory. She liked teaching and her students were inspired by her experience and competence.

Maria retired in 1888 because she had health problems. She was single and so she died, aged 70, at her sister’s in 1889. The Nantucket Observatory was named after her, as well as, a crater on the Moon and a World War II liberty ship. She is in the National Women’s Hall of Fame. She always said: “We have a hunger of the mind. We ask for all of the knowledge around us and the more we get, the more we desire.”

SCIENCE

The Sun Thanks to scientists, we know a lot about the Sun. The Sun is really old: it is about 150 million kilometers far from the Earth.

The Sun is so large that its diameter is 109 times the Earth’s.

The Sun is made up of 75% hydrogen and 25% helium.

Hydrogen is the simplest and lightest of all of the known elements. When you combine hydrogen with oxygen, you get water.

You probably know what helium is. It is the gas that can be put into balloons to make them stay in the air and float.

The surface of the Sun is about 5,600 degrees Celsius. That might sound hot, but the Sun’s centre is even hotter. The core is the central region where the temperature reaches about 15 million degrees Celsius.

The Sun is the centre of our Solar System, where we also have other planets, moons, asteroid belts, comets, meteors, and so on. Our Earth and other planets revolve around the Sun which is very important because, without it, we would have constant darkness. So, our planet, would be really cold and we wouldn’t have liquid water! You can imagine there wouldn’t be any people, animals, plants as they live if they have sunlight and water.

The Sun also gives out dangerous ultraviolet light which causes sunburn and may cause cancer.

That is why you need to wear sunscreen and clothing to protect yourself from its rays.

Scientists study the Sun using special tools or instruments such as telescopes. One thing they do is to look at the amount of light from the Sun and the effect of the Sun’s light on the Earth’s climate.

SCIENCE

The Moon The Moon orbits the Earth and the side that points towards our planet is always the same.

It is the second brightest object in the sky.

We use the term “object” because we can describe it as a huge ball of rock. Its surface is dry, in fact there is no water, and there are craters made by meteorites. There are also big mountains and valleys. There are no living creatures on the Moon as the temperature varies a lot because of the lack of atmosphere. So, it can be 120°C during the day and -230°C at night.

Light is not present on the Moon: we see it, because light from the Sun falls on it reflecting back to Earth. If we look at the sky at night, the Moon sometimes “shimmers”. This word means shining softly or with a flickering light or glow. We see the Moon because the Sun is shining on it!

When the Moon passes between the Sun and the Earth, its shadow falls on the Earth and we can see some parts of the Sun covered by the Moon. This is called a “solar eclipse”. Solar eclipses take place twice a year. There is a “lunar eclipse” too. This happens when the Moon passes through the Earth’s shadow and this blocks the sunlight from hitting the Moon. It can happen more than twice a year.

The astronauts Neil Armstrong and Buzz Aldrin flew on the Apollo 11 rocket and landed on the Moon. On 20th July 1969, they were the first people to walk on it. Another astronaut, Michael Collins, was with them but he stayed in orbit around the Moon, and didn’t walk on it.

They also brought back some rocks to study. Scientists discovered that they were similar to the rocks on Earth but really old: they were 4 billion years old!

TECHNOLOGY

Solar Energy The sun produces energy in the form of light which comes as ultraviolet, visible and infrared rays.

When we see the spectrum of colours, we see visible sun rays. Ultraviolet and infrared ones cannot be seen.

Solar energy is a renewable source of energy which does not damage the environment. As long as there is sunlight, we will be able to get power from it.

This kind of energy doesn’t release carbon dioxide and pollution into the air, so it can be defined as a clean source of energy which reaches the Earth with its solar radiation.

Solar radiation gives also power to all living things through photosynthesis. Photosynthesis takes place when plants use the sun's energy to make its own food, and then of course, all other living organisms eat the plants receiving that energy indirectly from the sun.

Collecting solar power to create electricity and heat is not as easy as photosynthesis. One way is to use sunlight that hits solar thermal panels. In this way solar energy can be converted and used efficiently to heat and light things like buildings, swimming pools, hospitals, schools.

Some Facts about Solar Power for Electricity 4

Read the following text on solar power for electricity. Answer the questions (1-7). Use a maximum of 4 words. Write your answers in the boxes. The first one (0) is an example.

When we think about solar power, we think about the solar cells that turn the sun rays into electricity. Solar cells are also called photovoltaic cells. “Photovoltaic” derives from the words “photons”, the parts that make up sunlight, and “volts”, the measurement of electricity.

Solar cells are used in small devices like calculators and wrist watches. They are also used for buildings and homes because they are a more efficient way to get electricity. In fact, if we place solar cells on the roof of a building or a house we can have green electricity: the solar cells convert the energy of photons from the sun into electricity.

We need a lot of solar cells to power a house, so a lot of them are connected together producing a large amount of energy. The photovoltaic cells were invented in 1954 and mainly used in small objects like calculators. Then, they were used for spaceships and satellites. In the 1990s people received incentives to buy them because they were considered a clean and renewable source of energy for their houses.
