up and Reading IUnit 3 Inventors and inventionsWarming up:In groups, discuss the inventions you know and then make a list.Warming up-I (4m)Do you know what these inventions are and when did they happen?Telephone 1876television 1923 colour television 1940photocopier 1937air conditioner 1902electronic digital computer 1942Atomic bomb 1945Credit cards 1950Penicillin 1928Among the inventions above, which invention do you think is the most important one? Why?Warming up – II (2m)What is an invention?An Invention is something that is created by a human being. Inventing is a scientific activity. Warming up-III (2m)What is a discovery?A discovery merely makes known something that already existed in nature.Look at the pictures below and discuss in pairs which pictures show inventions and which show discoveries. Pre-reading – I (4m)An amphibious car(2003)This is the first car that can travel safely on water and on land. When moving on water, the wheels of the car turn sideways and move into the body. The underneath of the car is strong enough to sail as a boat. It is a prototype and is not yet being produced for sale. This is an interesting modern invention.Stephenson’s “Rocket” (1781-1848) George Stephenson was one of the first men to design engines for the railways which were new at that time. One of the first tracks to be laid was between Stockton and Darlington. Stephenson was one of the first railway engineers and in 1825 he drove the first train along the line.The structure of DNAThis was a discovery of Francis Crick and James Watson and published in 1953. These two scientists were the first to show that our genes consist of two spirals of DNA (called the double-helix). This work led directly to the human genome project in 2003, which discovered the Structure of DNA.Do you know the stages every inventor must go through before they can have their invention approved? Inventing is a scientific activity and so follows similar stages to those used in scientific research. Look at the list and work out a suitable order.Applying for a patent

Why was the writer happy to help her mother?The mother was upset because a family of snakes had made their home near the house.The writer was happy because it gave her an opportunity to help her mother and invent something to catch the snakes without hurting them at the same time.3.What are the three creative steps that the writer takes to catch the snakes without hurting them?Step 1: She bought a stainless steel ice cream maker and froze the bowl. She added ice cubes to the top of the bowl to keep it cold. She placed it over the snakes’ habitat during the day so that the snakes would become sleepy and could be easily caught.Step 2: As above she did the same but placed the bowls over the snakes’ habitat in the evening.Step 3: As above but added a net to catch the snakes.4. Why did cooling make the snakes less active?Snakes do not have a way of keeping warm in their bodies. They get warmth from the sun and become more active at this time. When the sun goes down at night they cool down and become less active. So extra cooling to the snake would make them even less active and easier to catch.Assignment1.Go over the whole passage.
2.Recite the key sentences in the text.
3.Prepare for Learning about Language in the textbook.
