人教版新课标高中物理必修1探究加速度与力、质量的关系教案2篇
1．加速度与力的关系：实验的基本思路是保持物体的质量不变，测量物体在不同的力的作用下的加速度，分析加速度与力的关系。有了实验的基本思路，接下去我们就要准备实验器材，以及为记录实验数据而设计一个表格。为了更直观地判断加速度与力的数量关系，我们以 为纵坐标、 为横坐标建立坐标系，根据各组数据在坐标系中描点。如果这些点在一条过原点的直线上，说明 与 成正比，如果不是这样，则需进一步分析。2．加速度与质量的关系：实验的基本思路是保持物体所受力不变，测量不同质量的物体在该力作用下的加速度，分析加速度与质量的关系。有了实验的基本思路，接下去我们就要准备实验器材，以及为记录实验数据而设计一个表格。为了更直观地判断加速度与质量的数量关系，我们以 为纵坐标、 为横坐标建立坐标系，根据各组数据在坐标系中描点，根据拟合的曲线形状，初步判断 与 的关系是反比例函数。再把 图像改画为 图像，如果是一条过原点的斜直线，说明自己的猜测是否正确。
人教版新课标高中物理必修1质点参考系和坐标系教案2篇
（创设实例：多媒体播放视频刘翔的110m栏。）1．提出问题：怎样定量（准确）人描述车或刘翔所在的位置？2．提示：你的描述必须能反映物体（或人）的运动特点（直线）、运动方向、各点之间的距离等因素。3．总结：①为了定量地描述物体的位置及位置的变化，需要在参考系上建立适当的坐标系。坐标系是在参考系的基础上抽象出来的概念，是抽象化的参考系。为了定量地描述物体的位置及位置的变化需要在参考系上建立适当的坐标系，如果物体在一维空间运动，即沿一条直线运动，只需建立直线坐标系，就能准确表达物体的位置；如果物体在二维空间运动，即在同一平面运动，就需要建立平面直角坐标系来描述物体的位置；当物体在三维空间运动时，则需要建立三维坐标系。①一维坐标：描述物体在一条直线上运动，即物体做一维运动时，可以以这条直线为x轴，在直线上规定原点、正方向和单位长度，建立直线坐标系。如图1-1-1所示，若某一物体运动到A点，此时它的位置坐标XA＝3m，若它运动到B点，则此时它的坐标XB＝-2m（“-”表示沿X轴负方向）。
人教版新课标高中物理必修1重力基本相互作用教案2篇
阅读教材后总结：是万有引力的作用把宇宙中的恒星和行星聚集在一起，组成了太阳系、银河系和其他星系.力的相互作用遍布我们周围的一切物体.除此之外还有电荷间的相互作用、磁体间的相互作用，我们把这种力称为电磁相互作用.【思考与讨论】质子带正电，但质子（与中子一起）却能聚集在一起构成原子核.你能推测是什么力的作用结果吗？攻略一：阅读教材53页，师生共同讨论、总结.攻略二：网络搜索或工具书查阅“四种基本相互作用”，进一步了解概念.结论：决定物质的结构和变化过程的基本的相互作用.近代物理确认各种物质之间的基本的相互作用可归结为四种：引力相互作用、电磁相互作用、弱相互作用和强相互作用.近代物理的观点倾向于认为:四种基本相互作用是统一的，物理学家们正在为建立大统一理论而努力.但至今也没有公认的结论，望同学们好好学习，为科学事业奉献自己的聪明和才智.
人教版新课标高中物理必修1运动快慢的描述─速度教案2篇
生：还可以从表盘上直接读出公里里程．师：日常生活中的“速度”有时指速度，也有时指速率，要看实际的物理情景。[讨论与交流]甲、乙两位同学用不同的时间围绕操场跑了一圈，都回到了出发点，他们的平均速度相同吗?怎样比较他们运动的快慢?学生讨论，体验平均速度的缺陷，引入平均速率。生1：位移都是零，平均速度等于位移跟发生这段位移所用时间的比值，所以他们的平均速度都是零。生2：即使一位同学站在原地不跑，他的平均速度也是零啊，可我们运动会上不是这样比快慢的，如果这样，那多不公平啊?师：平均速度v=Δx/Δt，甲、乙的位移都为零，所以他们的平均速度也都等于零．在这里平均速度无法显示他们运动快慢的不同，要用到另一物理量：平均速率．平均速率等于物体运动通过的路程跟所用时间的比值．他们两人通过的路程相同且都不为零，但所用时间不同．显然用时短的运动得快，也就是平均速率大．生：这不是我们初中学过的速度吗?

新人教版高中英语必修3Unit 1 Festivals and Celebrations-Listening &Speaking＆Talking教学设计
The theme of this section is “Talk about festival activities and festival experiences”.Festival and holiday is a relaxing and interesting topic for students. This part talks about the topic from the daily life of students’. In the part A ---Listening and Speaking, there are three conversations among different speakers from three countries(Japan, Rio and China), where the speakers are participating in or going to participate in the festivals and celebrations. So listening for the relationship among them is a fundamental task. Actually, with the globalization and more international communication, it is normal for Chinese or foreigners to witness different festivals and celebrations in or out of China. In the Conversation 1, a foreign reporter is interviewing a Japanese young girl who just had participated in the ceremony of the Coming-of-Age Day on the street and asking her feeling about the ceremony and the afterwards activities. Conversation 2, Chinese girl Li Mei is witnessing the Rio Carnival for the first time, and her friend Carla gives her some advice on the costumes which enables her to match with the carnival to have a good time. Conversation 3, a Chinese guide is showing a group of foreign visitors around the Lantern Festival and introducing the customs of the festival to them. The three conversations have a strong vitality and insert the festival and cultural elements from different countries. So perceiving the festivals and cultures from different countries is the second task. At the same time, the scripts also insert the targeted grammar --- v-ing as attributive and predicative, which students can perceive and experience in a real context and make a road for the further study. That is the third task. In the Part B--- Listening and Talking, the theme is “Talk about festival experience”, which is the common topic in our daily conversations. During the conversation, Song Lin, a Chinese student, asked Canadian friend Max about how to spend Christmas. In the conversation, Song Lin talked about experience and the feelings during the Chinese Spring Festival, during which there are not only some enjoyable things but some unpleasant things. After the listening, perhaps students find there are some similarities between Christmas and the Chinese Spring Festival as there are some differences in the origins and celebrations. For example, people always visit friends and relatives, decorate their houses, have a big dinner together, chat and give presents to each other.

Step 3 Analyzing article structureActivity 31. Teachers raise questions to guide students to analyze the chapter structure of this diary and think about how to describe the festival experience. (1)What should be included in the opening/body/closing paragraph(s)?(2)How did the writer arrange his/her ideas?(3)What kind of interesting details did the writer describe?(4)How did the writer describe his/her feelings/emotions during the event?2. Students read and compare the three sentence patterns in activity 2. Try to rewrite the first paragraph of the diary with these three sentence patterns. After that, students exchange corrections with their partners. Such as:●This was my first time spending three days experiencing the Naadam Festival in China’s Inner Mongolia Autonomous Region and it was an enjoyable and exciting experience. ●I'll never forget my experience at the Naadam Festival because it was my first time to watch the exciting Mongolian games of horse racing, wrestling, and archery so closely. ●I'll always remember my first experience at the Naadam Festival in China’s Inner Mongolia Autonomous Region because it was so amazing to spend three days witnessing a grand Mongolian ceremony. Step 4 Accumulation of statementsActivity 41. Ask the students to read the diary again. Look for sentences that express feelings and emotions, especially those with the -ing form and the past participle. Such as:● …horse racing, wrestling, and archery, which are all so exciting to watch. ● some amazing performances● I was surprised to see…● I was a little worried about. . . ● feeling really tiredOther emotional statements:●I absolutely enjoyed the archery, too, but the horse races were my favourite part. ●I'm finally back home now, feeling really tired, but celebrating Naadam with my friend was totally worth it. ●He invited me back for the winter to stay in a traditional Mongolian tent and cat hot pot. I can’t wait!2. In addition to the use of the -ing form and the past participle, the teacher should guide the students in the appreciation of these statements, ask them to memorize them, and encourage them to use them reasonably in writing practice.

The topic of this part is “Write about your festival experience”.During the Listening and Speaking and Talking, students are just asked to say out their festival experiences such as the Spring Festival, Mid-autumn Day, but this part students will be asked to write down their own festival experiences. During the reading part, it introduces the Naadam Festival in Inner Mongolia Autonomous Region, which can give students a good example to imitate.

Then it introduces the items of the festival like the ceremony, wrestling and horse racing. Finally, it summarizes this experience. Because this part is a travel journal, we must guide students pay more attention to these details: 1. use the first person. 2. use the past tense to tell the past thing and use the present or future tense to describe the scenery. 3. use the timeline to tell the development. 4. be careful for the author’s psychology, emotion and feeling, etc.1. Read quickly to get main idea; read carefully to get the detailed information about Naadam Festival.2. Learn the structure of the reading article and language.3. Write an article about a festival experience4. Learn to use the psychology, emotions and feeling in the writing.1. Write an article about a festival experience.2.
