NSEFC Module 8学案二Get to know some necessary background knowledge:Introduction to the Unit:Inventing is a scientific activity because it uses the same procedures as scientific experiment. It is also a creative activity. So to be a good inventor, you need to be imaginative as well as disciplined in your approach. One of the important aims of this unit is to identify and set out the steps that should be followed by any inventor. Another is to make clear the difference between a discovery and an invention. The third is to introduce the readers to the role of the patent office in deciding what is an invention and what is not.Inventing has been a part of human life as long as humans have been on the earth. If you go into a museum, you will see the stone axes, pots and fishing hooks, which were the inventions of our ancestors. Each is the result of successful experiments by early man into problems such as how to cut down trees, cook and store food and water or catch fish. Many objects that we have around us today are similar modern inventions. The mobile phone solves the problem of how to contact someone while you are on the move. The television solves the problem of how to spread news and entertain people at home. The washing machine helps us to keep our clothes clean and lighten our work. So inventors and inventions are not new and each one answers a particular need or solves a problem. Work out the rules that will help you decide what a discovery is and what an invention is.Work out the connection between a discovery and an invention: discoveries often lead to inventions. Read the following:DiscoveriesInventions1.electricity1. Systems of delivering electrical light and heating to homes and offices.2. Household machines for washing, ironing, keeping food cold, etc.3. Computers, telephones, television, etc.2. the movement of air 1. Airplane jet engines2.Air balloons, etc.3. the circulation of the bloodMachines to help people with serious disease(like kidney failure)4. X-rays1. Body scanners to see whether you are ill.2. Machines to treat illnesses(like cancer)A discovery is_____________________________________________________.用心 爱心 专心1An invention is ___________________________________________________.Invention is generally thought to make, design or produce something new for the first time. In fact inventing goes through much the same stages as you do with a scientific experiment. The first and the most important stage is to identify a problem that needs a solution. Look at the following list and work out a suitable order.Applying for a patent Finding a problem Doing research Testing the solution Thinking of a creative solution Deciding on the invention1.___________________ 2._________________ 3._________________ 4.___________________ 5._________________ 6.________________用心 爱心 专心2
