Read the texts (1-6) and match the titles with the paragraphs (A-E)
• Finding the evidence
• What's in a name?
• Small but significant
• An impossible idea
• Putting it all together
1. Meet Mesosaurus, a small reptile which lived in fresh-water lakes and streams millions of years ago during the lower Permain age. Mesosaurus has had a big impact on how we view our planet, because he helped to prove the existence of the super-continent called Gondwanaland.
2. Every schoolchild has probably looked at a map of the earth and noticed how Africa and South America fit together like pieces of a giant jigsaw, yet until just over a hundred and fifty years ago, no-one believed that this was more than an odd coincidence. It seemed impossible that the massive continents of the earth could ever be moved, let alone so far apart that they ended up half a planet from each other.
3. Nevertheless, in 1912 Alfred Wegener, a German meteorologist came up with the theory that the continents of the earth had all existed in a single mass, which he called Pangaea (which is Greek for “all the world”) Later researchers decided that Pangaea had been two continents, one to the north of the other, which had existed about 250 million years ago. From the geological evidence found in the Gondwana area of India, an Austrian geologist, Eduard Suess coined the name 'Gondwanaland' for the southern supercontinent, of which India was once a part. (The northern continent was called Lurasia.)
4. For many years super-continents were regarded as an interesting theory, but no-one knew how it might work in reality. Then the discovery of the mechanisms of plate tectonics showed how continents might drift across the face of the globe. Once it was accepted that the continents were floating on currents of lava, more evidence became apparent. A particular type of an early plant, the seed fern, was found on continents now scattered about the southern hemisphere of the world, as were tillates, a deposit left by glaciers in the Permo-Carboniferous era of 520 million years ago. And Mesosaurus, the little fresh-water reptile, left his remains in West Africa and Brazil. Since Mesosaurus had no way of crossing the Atlantic, researchers realized that it could not be coincidence that this reptile had left remains in exactly the place where Africa and South America fit together so neatly.
5. By investigating similarities in animal fossils, different types of plants found in the southern hemisphere but not in the northern hemisphere, and patterns of rock formations, researchers have managed to put the continents of modern-day earth together like a huge jigsaw to make up the vanished super-continent. Sometimes rock formations can be seen to break off at the ocean's edge, to carry on once more thousands of miles away on another continent. The evidence shows that not only were Africa and South America once joined to Antartica, but so were India and Australia, parts of south Western Europe, and Florida.

Ученики 4-го класса проводили опыты с целью изучения свойств воды. Они хотели выяснить, влияет ли объём воды на скорость, с которой вода из жидкого состояния полностью переходит в газообразное. Ребята взяли две колбы с мерными делениями. В одну колбу налили воды в два раза больше, чем в другую. Обе колбы учитель поставил нагревать на спиртовках.



Если бы ученики захотели выяснить, влияет ли температура на скорость, с которой вода полностью переходит в пар, с помощью какого эксперимента они могли бы это сделать? Опиши этот эксперимент.
