.In pairs discuss which
of these pictures show
inventions. Does any of them
show discoveries?An amphibious car水陆两用汽车It is an invention4An 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”It is an invention6Stephenson’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.DNAIt is a discovery.8The 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.2. Work out two rules that will help
you decide what is a discovery and
what is an invention?
10What is an invention?An Invention is something that is created by a human being. Inventing is a scientific activity. Warming up-III (2m)11What is a discovery?A discovery merely makes something that already existed in nature known . Let’s work out the connection between

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.29Finding a problemDoing research Thinking of a creative solutionTesting the solutionDeciding on the inventionApplying for a patentThe steps of inventing30Patent office (专利局) plays the role of deciding what is an invention and what is not. And only inventions can get patens and so be recognized and protected.patentsAs you read the following passage, check
the order you wrote above to see whether
it follows the correct stages in producing
an invention.The Problem ofthe snakesReading33Reading
