Finding a problem

Doing research

Testing the solution

Step1. Preparing Thinking of a creative solution

Deciding on the invention lessons &self-study and Answers: The suitable order:Finding a problem--Doing exploring the research ---Thinking of a creative solution---Testing the solution---Deciding on the invention--Applying for a problems

(预习自学，探究问patent Patent office (专利局) plays the role of deciding what 题) is an invention and what is not. And only inventions can get

patens and so be recognized and protected. 2)Among the inventions above, which invention do you think is the most important one? Why? What is an invention? An Invention is something that is created by a human being. Inventing is a scientific activity.

What is a discovery? Get the Ss to look through Warming-up and Pre-reading to do some exercises. （The aim is to direct the students to understand the topic and to gain the useful information about invention and patent .）

A discovery merely makes known something that already existed in nature.

Answers: 案，提出问题）

Part I (Para.1)The discovery of the problem of the

snakes. Part II(Paras2-3)The research on the approaches to solve the problem. Part III(Para. 4-6)The attempts to catch the snakes. Part IV(Para.7-8)The requirement of getting a patent.

Task4. Detailed reading:(5m) Answer the following questions: 1.What was the mother upset about? 2.Why was the writer happy to help her mother? 3.What are the three creative steps that the writer takes to catch the snakes without hurting them? 4.Why did cooling make the snakes less active?+ 5.Discuss with your partner what the advantages might be of getting a patent. Suggested answers: 1.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 Step3.Researching 2.opportunity to help her mother and invent something to cooperatively& catch the snakes without hurting them at the same time. answering questions(合作探3.Step 1: She bought a stainless steel ice cream maker and froze the bowl. She added ice cubes to the top of the 究,

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.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. 5.You are able to prove that you are the first person to make the invention;

Step1.Check the answers and review something in Warming up. Get the students to scan the passage---- THE PROBLEM OF THE SNAKES in groups and do the comprehensive exercises. (The aim of this part is mainly to improve the students’ reading skills.)

Let students read the passage carefully to get some detailed information, thus have a better understanding of the passage. Step2.Ask the students to read the passage again and finish Task4 in groups. (The purpose is to improve the students’

ability of looking for useful information.)
