Work in groups. Follow the steps of the jigsaw reading.
- a) Read the article your teacher gives to your group. Help each other to understand it. Use a dictionary if necessary.
b) Fill in your line in the table. Use your Workbook.
c) Form new groups with at least one member from each of the other groups. Do not show your notes to the new group.
d) Take it in turns to ask and answer questions about the different articles so that you can fill in the whole table.
e) Go back to your first group. Compare your notes and reconstruct the rest of the articles. Read them aloud in your groups.
f) If you have difficulties reconstructing the articles, ask questions to clear them up.
Here is a concise reconstruction of the articles from the jigsaw reading.
Are aliens coming?
People have been searching for extraterrestrials for years, but there is no real proof that they exist. Still, interest in UFOs appears again and again when new “facts” — real or imaginary — are reported. In the age of globalisation, such waves of interest spread all over the world very quickly thanks to TV and the Internet.
For example, some years ago the “Roswell case” caused a hot discussion in the USA. A film showing the autopsy of an alien who died in a UFO crash in 1947 in Roswell, New Mexico, was presented as real proof that extraterrestrials exist. However, the US Committee for the Scientific Investigation of Claims of the Paranormal examined the film carefully and proved that it was not real.
Great inventions
Inventors come up with all sorts of crazy ideas and create many strange things. Cars that run on water and machines that generate energy are just some examples of what has been invented.
One of the first world-known perpetual motion machines was invented by Charles Redheffer and exhibited in Philadelphia and New York at the beginning of the 19th century. Hundreds of people paid a dollar to see it, and the invention became a profitable business. The machine really looked as if it was turning by itself without any power. But it became obvious that there was actually a man off-site turning the crank.
One hundred and fifty years later, another American, Joe Newman, presented his “energy machine”. He persuaded people that if they bought one, they could forget about electricity bills. Some people believed him and later could not understand why they were still getting electricity bills.
IQ — a number that influences your life
IQ is a number that we think shows a person’s intelligence. But what does it depend on? For many years scientists believed that IQ was mostly inherited.
One of the largest IQ studies was held by Sir Cyril Burt, professor of psychology at University College London. He based his theory on studies of twins and proved that IQ was really mostly inherited. His study was the largest, and the results looked truly representative. Even sceptics believed them. As a highly respected scientist, Burt supported the much-debated 11+ exam and thus influenced children’s school life throughout Britain.
Burt died in 1971, and it was a shock when scientists found out that many results left by the professor could not be called scientific, as they were not supported by real figures. What is more, some of his IQ studies did not exist at all, and even the names of his assistants were invented by the professor. So, the role of genes in IQ is still under discussion.
Crop circles
Some people think crop circles have been caused by aliens, but there are really no reliable theories about how they appeared. They were first noticed in fields in southern England in the 1970s, and then spread all over the world.
People reported that they had seen balls of light and heard high-pitched noises over the fields. Various “scientific” explanations appeared immediately. Some researchers blamed tornadoes, while others blamed “directed plasma” and geomagnetic currents running through the Earth. Alien-related theories also appeared, and military experiments started being connected with crop circles.
The circles were given mysterious or religious meanings, and even healing powers. The discussion was hot and unresolved when a pair of frauds confessed that they had used a special press to make the circles. But it was too late — many people still want to know why there are crop circles all over the world.
