I am very glad to perform my lesson here and please permit me to say “Thank you for your time” in advance.First let me say something about my lesson. I choose Lesson 30 of Student Book Four. The title is Keep the Candle Burning. After I analyze this lesson, I want to get two aims. My basic aim is to teach the students some new words. To achieve this goal, I prepare some real objects. With Changyan Language System, I place some tags on them. It can read the word and can make some sentences as well, just like this………In this way, the students can connect the sound and the object together, and I think it is much easier for them to master the new words. My ability aim is to let the students do the experiment by themselves according to the instructions Changyan Language System gives them. While doing the experiment, they can both practice their listening and increase their interests of learning English. So much for this. Thank you.▃▄▅▆▇██■▓点亮心灯 ~~~///(^v^)\\\~~~ 照亮人生▃▄▅▆▇██■▓。

冀教版英语八年级下册LookintoScience说课稿说课稿冀教版八年级下册Lesson 29 Unit 4南安六中许小为一、教材分析㈠、教材的地位及作用本单元的中心话题是“研究科学”——Look into Science,整个单元围绕“科学研究”展开，而本课是关于复活节庆祝活动的内容，从内容来看，它在本单元中是孤立的，既不承前，也没启后。

但它在本单元衔接前后两个抽象的科学实验，像课间的十分钟，能调节学生疲惫的神经，放松紧张的气氛，激发他们的学习热情，为他们学习后半单元做准备。

而且，在知识结构方面，它也与本单元的前几课联系密切，进一步巩固一般将来时的用法和表示肯定的语法功能，是知识功能的延续。

㈡、教学目标1、知识目标⑴掌握重点单词：basket, hide ,everywhere。

⑵区别find ,look for与hunt for的用法。

⑶掌握和运用一般将来时及表示确定的语言功能。

2、能力目标⑴、听懂简单故事的情节发展，理解其中主要人物和事件。

⑵、在教师的指导下参与角色扮演等活动。

⑶、从简单的文章中找出有关的信息，理解大意。

3、德育目标使学生更多地了解西方文化，深刻理解节日的历史和现实意义，培养多元文化知识，提高文化修养。

培养学生学会制定计划的好习惯，使学生开始做任何事情之前，能提前制定一个计划，掌握做事情的方法或顺序等有关事项。

㈢、重点与难点重点：学习掌握单词basket, hide, everywhere, 能运用一般将来时和表示确定的语言功能。

难点：find,look for与hunt for的区别。

二、学生情况分析总的来说，我班学生趋于内向，羞涩感较强，自我表现不积极，能主动回答老师问题的学生不多，课堂学习气氛较不强烈。

但是整个班级的知识结构相对扎实，英语成绩呈橄榄行，尖子生和差生相对较少，中等生占绝大多数。

加上天气原因，学习情绪一般。

三、教学思路与方法遵循英语教学规律及学生的基本情况，主要采用如下的教学策略：⒈情景教学法借助现代电解手段——多媒体辅助教学，使学生身临其境，也增加直观性和趣味性，调动了学生的积极性和主动性。

Is it possible to stick a needle through a balloon without popping it?MaterialsYou will need the following materials:• balloons• long wooden or metal skewers(棒)• petroleum jelly（凡士林油）• a sharp pin• cellophane （玻璃纸）tapeProcess1.Blow up a balloon – not too full – and tie the opening shut.2.Dip the tip of a skewer in Vaseline and spread the Vaseline along the entire lengthof the skewer. If you are careful, you should be able to push the skewer all the way through the balloon without popping it. Insert the skewer with a gentle twisting motion into the end of the balloon opposite the knot. Continue pushing and twisting the skewer until the tip emerges from the other end, near the knot. Why doesn't the balloon pop?3.Now try to stick the skewer into the side of the balloon. What happens? ExplanationThe rubber in the balloon consists of many long molecules(分子) that are linked together. It's similar to the way all of the noodles in a plate of spaghetti stick together. These long molecules are called polymers（聚合体）; when molecules of a polymer are chemically attached to each other, it is called cross-linking（交叉结合）. These links hold the polymer molecules together and allow them to stretch…up to a point. When the force or tension pulling on the cross-links is too great, they will break, and the polymer will pull apart.Look at the rubber near the ends of the balloon where you first inserted the skewer. Does it look lighter or darker than the rubber in the rest of the balloon?The rubber at the ends of the balloon is stretched out less than in the middle of the balloon. Therefore, there is less force pulling on it. This allows the tip of the skewer to break some polymer cross-links, push aside the molecules of rubber, and slide into the balloon. However, enough cross-links remain so that the balloon holds together.In the side of the balloon, there are fewer polymer molecules. When you push the tip of the skewer through the rubber in the side of the balloon and the skewer breaksa few of the cross-links, the tension on the remaining cross-links is too great, and the balloon pops.Do you think there is a way to stick a sharp pin through the side of a balloon without popping it?Put a small piece of cellophane tape on the side of the balloon and press it down well. Now take the pin and press it through the tape and into the balloon. Does the balloon pop?The tape sticks to the rubber in the balloon and will not allow the rubber to stretch to the breaking point when the pin pierces the balloon. In other words, the tape reinforces the cross links, and the balloon stays together.II Experiments for kids1. INDOOR RAINBOWMATERIALS:∙glass jar or a large drinking glass∙small mirror∙flashlight∙dark room with white wallsPROCESS:Fill the jar or glass with water.Place the mirror inside the water filled jar or glass.Tilt the mirror slightly upward.In a very dark room with white walls, shine the flashlight onto the mirror.A rainbow will appear! (Note: If no rainbow appears at first, just change the angle of the light from the flashlight or change the angle of the mirror.) EXPLANATION:The mirror reflects light that passes back through the water, traveling at an angle. The water bends, or refracts, the light. As the light bends, it separates into the colors of the rainbow...red, orange, yellow, green, blue, indigo and violet.2. MAKE FOGMATERIALS:∙glass jar∙strainer∙water∙ice cubesPROCESS:Fill up the jar completely with hot water for about a minute.Pour out almost all the water, but leave about one inch in the jar.Put the strainer over the top of the jar.Place a few (3-4) ice cubes in the strainer.Watch what happens!EXPLANATION:The cold air from the ice cubes collides with the warm, moist air in the bottle causing the water to condense and forming an eerie fog.3. MAKE A THUNDERSTORMMATERIALS:∙clear, plastic container (size of shoebox)∙red food coloring∙ice cubes made with blue food coloringPROCESS:Fill the plastic container two-thirds full with lukewarm waterLet the water sit for one minute.Place a blue ice cube at one end of the plastic container.Add three drops of red food coloring to the water at the other end of the plastic container.Watch what happens.EXPLANATION:The blue and cold water sinks while the red and warm water rises. This happens because of convection. The blue water represents the cold air mass and the red water represents the warm, unstable air mass. A thunderstorm is caused by unstable air and convection plays an important part. A body of warm air is forced to rise by an approaching cold front therefore thunderstorm’s form.4. BALLOON IN A BOTTLEMATERIALS:∙plastic water or pop bottle∙large bowl∙balloon∙ice water∙hot waterPROCESS:Fill the plastic bottle with hot water.Swirl the water around to make the bottle hot and then pour it out.Refill the bottle one-fourth full with hot water and place the balloon over the mouth of the bottle.Fill the large bowl with ice water and place the bottle in the bowl.Watch as all of the air is taken from the balloon. It might even get sucked into the bottle.EXPLANATION:What happens? The hot air in the bottle expands as the cool air outside the bottle contracts. When you first place the balloon over the mouth of the bottle, the air in the bottle is hot. As the air cools from the ice water outside the bottle it contracts and pushes the balloon into the bottle. This is why the air is taken from the balloon and sometimes gets sucked into the bottle.。

冀教版英语八下《Unit 4 Look into Science》(lesson30)word说课稿

名师精编优秀教案Lesson 30 说课稿东光县第三中学张淑杰Lesson 30 Keep the Candle BurningHello, everyone! My name is Zhang Shujie from No. Three Middle School of Dongguang. I am very glad to perform my lesson here and please permit me to say “Thank you for your time” in advance.First let me say something about my lesson. I choose Lesson 30 of Student Book Four. The title is Keep the Candle Burning. After I analyze this lesson, I want to get two aims. My basic aim is to teach the students some new words. To achieve this goal, I prepare some real objects. With Changyan Language System, I place some tags on them. It can read the word and can make some sentences as well, just like this………In this way, the students can connect the sound and the object together, and I think it is much easier for them to master the new words. My ability aim is to let the students do the experiment by themselves according to the instructions Changyan Language System gives them. While doing the experiment, they can both practice their listening and increase their interests of learning English. So much for this. Thank you.。
