Helping them enjoy science can be easy; there's no need for a lot of scientific terms or expensive lab equipment. You only have to share your children's curiosity (好奇). Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary (薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said，“Now that we've finished with your lists,_do you have questions of your own about science？”After a long pause, a boy raised his hand, “Have you ever seen a grasshopper (蚱蜢)eat? When I try eating leaves like that，I get a stomachache. Why？”This began a set of questions that lasted nearly two hours.Secondly，give them time to think. Studies over the past 30 years have shown that，after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and creative answers.Thirdly, watch your language. Once you have a child involved in a science discussion，don't jump in with “That's right” or “Very good”. These words work well when it comes to encouraging good behaviour (行为). But in talking about science，quick praise can signal that discussion is over. Instead, keep things going by saying “That's interesting” or “I'd never thought of it that way before”，or coming up with more questions or ideas.Never push a child to “think”. It doesn't make sense. Children are always thinking，without your telling them to. What's more, this can turn a conversation into a performance. The child will try to find the answer you want，in as few words as possible，so that he will be a smaller target(目标)for your disagreement.Lastly, show; don't tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass (放大镜) ，and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.1. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is ________.A．to let them see the world aroundB. to share the children's curiosityC. to explain difficult phrases about scienceD. to supply the children with lab equipment2．In the last sentence of the first paragraph, the underlined word “lists”could best be replaced by ________.A．any questionsB．any problemsC．questions from textbooksD．any number of questions3．According to the passage, children can answer questions in a more logical, complete and creative way if adults ________.A．ask them to answer quicklyB．wait for one or two seconds after a questionC．tell them to answer the next dayD．wait at least for three seconds after a question敬请批评指正。

完整教案外研版必修一Module 5 A Lesson in a Lab Period 1Teaching aims:1. To introduce some general science.2. To learn some words related to the theme of this module.3. To develop speaking ability by practicing saying the numbers, especially the fractions. Important and difficult points:1. Arouse the students' interests and love in science.2. Enable the students to understand some elements about the chemistry lab.3. Make the students know how to read the numbers.Teaching procedures:Step 1. IntroductionActivity 1The aim of the activity is to ask the students to finish the quiz about general science to arouse their interest in science.The activity can be done as follows:Firstly, ask the students to go through the following the quiz and make their choice on their own. Quiz: How much do you know about general science?1. Water exists __________.(b) as a solid and a liquid only (a) as a solid, a liquid and a gas2. When you heat a metal, it will ___________(b) contract (a) expand3. Steel is mixture of_____________.(b) iron and oxygen (a) iron and other substances.4. _______________ of the earth's surface is water.(b) 50%(a) Two-thirds5. The distance of the sun from the earth is ______________ kilometers.(b) 150,500,500(a) 25,5006.The earth is 4.6______________ years old.(b) billion(a) million7. The earth is ______________ the moon(b) forty-nine times larger than(a) twice as large asThen put the students in pairs to compare their answers and call back the answers from the class. Finally ask them to listen to the tape about the above quiz and check their answers.Answers: 1. a; 2. a; 3. a 4. a; 5. b; 6. b; 7. b.Activities 2 & 3The teacher can prepare some cards about different things for the class at first. Before showing the students the cards,the teacher can say to the whole class: Things can be divided into three kinds, natural, man-made, and either natural orman-made, now I'll show you some cards in my hand, can you tell me which are natural, man-made or both?1 / 12the divide some examples? Then say to the whole the class: Can you give teacher After this, the can continue towhole class into two big groups to compete. The teacher can ask the Ss to speak out as many examples as possible and writeFinally, ask the Ss to open their books at Page 41 and read the words in the box aloud. If possible, they can look up thewords to know what they mean. Of course, the above competition will continue, that is to say, at this moment, the teachercan ask the Ss to put the words in the box on Page 41 in their books in the above table.Step 2. Vocabulary and SpeakingActivity 1The aim of the activity is to have the students know how to read the long numbers. So the activity can be done likethis:Before dealing with the activity, the teacher had better build up a long number byhaving the students say an increasing sequence, eg:three 3thirty-three33three hundred and thirty-three333three thousand, three hundred and thirty-three 3, 333thirty-three thousand, three hundred and thirty-three33, 333At this time, most of the Ss will know the way of reading these long numbers: where to say “million”, “thousand”, and“hundred”. So in order to consolidate what they just learned, the teacher can practice saying thenumbers at the top of Page42 with the students to make sure the Ss have the correct intonation.Then ask the Ss to go through the rest of the numbers in Activity 1 and find the errors individually according to thedirections.Finally the teacher calls back the answers from the class.Answers: 1)The word “thousand”is missing after “four hundred and seventy”; 2)The word “one”(or“a”) is missing before “hundred million”.Activity 2Firstly, the teacher point at the fractions and say them in English. At the same time the teacher have the Ss repeat themafter him or her.Then the teacher and the Ss make an analysis about the rules of reading fractions in English together. Finally the teacher ask the Ss to read the rest of the fractions in Activity 2 on Page 42 in their books in English on theirown. If necessary, the teacher can write down the correct answers on the blackboard to check what they read.Answers: 1. two-fifths; 2. five-eighths; 3. nine-tenths 4.three-eighths;5.five-sixths.Activity 3The teacher should introduce the concept of percentage at first, and then the teacher write down some percentages onthe blackboard and read them out in English.Eg: 35%→thirty-five percent (or: 35 percent); 50 percent equals a half.2 / 12Then have the Ss practice reading aloud the following percentages: 40%; 55%; 85%.Finally have the Ss work in pairs to describe the fractions in Activity 2 as percentages in English. Answers: 1. A quarter is the same as 25%; 2.One third is the same as 33.33r%(thirty-three point three recurringpercent); 3.Four-fifths is the same as 80%; 4. One tenth is the same as 10%; 5. Three-quarters is the same as 75%; 6. Onehalf is the same as 50%; 7. Two-thirds is the same as 66.66r%(sixty-six point six six recurring percent);8. Two-fifths is thesame as 40%; 9. Five-eighths is the same as 62.5%(sixty-two point five percent); 10. Nine-tenths is the same as 90%; 11.Three-eighths is the same as 37.5%(thirty-seven point five percent); 12.Five-sixths is the same as83.33r%(eighty-threepoint three recurring percent).Step 3. Homework1. Preview the reading part.2.Work in pairs to finish Activities 4& 5 on Page 43.Periods 2 & 3Teaching aims and demands:1. To learn about some vocabulary and knowledge related to science and experiments.2. To know about some metals and get to know their main uses in our lives.3. To make the students know how to do a simple experiment and write the report about it in English.4. To deal with all the activities1-6 about passage A and passage B on page 44-45.5. To develop students' expression ability as well as reading ability by practicing these two passages.6. To raise students' interests in science and form the rigorous scientific attitude.Teaching key points:1. To make the students understand and grasp the vocabulary and knowledge related to science and experiments.2. To enable the students to know how to read some passages about simple scientific experiments. Teaching difficulties:To make students learn how to write an experiment report in EnglishTeaching methods:⒈Communicative Approach⒉Task-based Approach⒊Aural-oral Approach with the help of the multi-media computer and the recorderTeaching aids:Multi-media computer; Software; PowerPoint; RecorderTeaching procedures:Step 1:Lead-inAt first show the students the picture of a lab with the help of computer.Then design the following questions and ask the students to discuss them in groups:Are you interested in doing scientific experiments?1.know about2.Suppose you want to do a chemical experiment about some metals, do you think it is necessary tohow they react with other substances?In order to carry out an experiment successfully, what should you prepare for it?3.3 / 12This step is to warm up the students and raise their interests to speak English in class. Because all these questions arey close to the students' daily life and studying ver Pre-readingStep 2.and vocabulary to know some in doing scientific experiments, now let's get you Teacher: Since are interestedknowledge related to science and experiments.as of the computer with metals on the screen the help At the same time I can type out some pictures about somefollows:) 钙calcium() ⑷magnesium(镁⑴potassium(钾) ⑵sodium(钠) ⑶)铜⑻copper( ) ⑺iron(铁) aluminium(⑸铝) ⑹zinc(锌What's this?
