Ice reading comprehension

Olvasáskészség fejlesztő feladat a jégről


You can skate on it, you can put it in drinks and it covers about 10% of the Earth’s surface – ice. It has some surprising behaviour and uses.

You might be surprised to know that water doesn’t always freeze at 0° Celsius. Ice needs something to form around, such as dust. If there is nothing for it to freeze around, you can lower the temperature of water down to –42° Celsius before it freezes. Another surprising fact is that hot water freezes more quickly than cold water. Aristotle was the first person to notice this in the fourth century BC, but it was Tanzanian schoolboy Erasto Mpemba who proved it in 1963 by demonstrating that a hot ice cream mixture freezes faster than a cold mixture. Scientists still don’t know why this happens.

Ice became very popular in London in the 19th century, a long time before people had fridges. The ice produced in the UK was not of good quality and there wasn’t enough, so it was imported from Lake Wenham in the USA. To show that the ice was good quality, a shop in London put a block of ice in their window every day with a newspaper behind it. The ice was so clear that you could read the newspaper through the ice and crowds of people came to see it every day.

Ice is also used to build things. Possibly the first ice structure was the Ice Palace in Saint Petersburg in 1740, to celebrate the 10th anniversary of the reign of the Empress of Russia, Anna Ioannovna. The Ice Palace had ice furniture and ice sculptures, including two elephants. As part of the celebration there was also a pretend ‘wedding’ of couples in traditional costumes from different areas of Russia. In 2006, ice artists recreated the Ice Palace using three tons of ice, but this time there were real weddings in the Ice Palace!

Another use of ice is for entertainment. When it’s winter in the northern hemisphere, there are ice festivals and ice sculpture competitions in many countries including Japan, Russia, Canada and Finland. Possibly the most famous is the Harbin Ice and Snow Festival in China, which attracts ice sculptors from more than 20 countries and displays around 2,000 ice sculptures, including sculptures of famous people, animals and famous buildings like the Eiffel Tower or the Great Wall of China.
