Today we’ll speak about inventions and inventors. We have learned some facts about useful inventions which were made in the long history of mankind. Most of them have really brought us comfort and convenience. We cannot imagine our life without electric lamps, cars or telephones, television or computers. Now, I offer you to do the following task. Read the sentences and change them from Active into Passive. Group 1. Alexander Graham Bell invented the telephone. Clyde William Tombaugh discovered the planet Pluto in 1930 Louis Braille invented a system of writing for blind people in the 19th century James Watt invented the stream engine Alexander Fleming discovered penicillin in 1928 John Spisbury made jigsaw puzzles in 1760. Group 2. Alexander Popov invented the radio Tomas Edison invented the lamp bulb Henry Edward Roberts invented the computer Altair 8800 in 1975 Alfred Nobel invented dynamite Columbus discovered America. The Chinese invented the compass. 4) Jigsaw reading. 1) Ex. II p. 39 – the two stories are jumbled up. Sort them out according to the titles: How did the microscope get invented? (Group 1) (A, E, F) The invention of the telescope (Group 2) (B, C, D, H) 2) What do these numbers mean? 1593, 1608, 400, 1st, 20-30, 4, 200 in about 1593 Zacharias Jansenn built the first microscope telescope was invented in 1608 more than 400 years ago Zacharias Jansenn made lenses for eyeglasses after the first telescope invention much more powerful telescope have been developed. The first microscope made things look 20 to 30 times larger than they are G. Galilei with the help of telescopes discovered Jupiter’s four largest satellites Anton Leeuwenhoek made microscope that could magnify objects up to 200 times 3) True or false sentences: Anton Leeuwenhoek made microscope that could magnify objects up to 200 times The microscope is the most important tool for investigating astronomy. Hans Lippershey placed two lenses inside a tube; distant objects seemed to be much closer. The first telescope helped us to learn about Solar System, the Milky Way and the universe itself. Galileo Galilei discovered Jupiter’s 4 largest satellites with the help of microscope. Historians believe that telescope was invented in 1608 in Holland Zacharias Jansenn built the first microscope in 1593 in Holland Key: 1) T 2) F 3) T 4) F 5) F 6) T 7) T Reflection People have invented a lot of useful things to make their life more comfortable. Almost every day a new technique or product appears in the world. But we always need something more useful, more effective and more comfortable. If you could invent anything you like, what would it be? What do you know about such inventions? 6 ) Homework Open your dairies and write down your homework Ex. 1 p. 40 – answer the questions. Learn the words by heart. The lesson is over! Your marks are … You may be free! Good bye! |
