人教版新课标小学数学四年级下册小数点位置移动引起小数大小变化说课稿
4、实际生活中的应用。提问学生：小数点位置移动引起小数大小的变化这规律在学习和生活有什么应用？（让学生思考在学习中，点错小数点的位置，小数的大小就不一样了。如果在银行统计时点错右漏写小数点会怎样？）教育学生做事认真细心。（四）小结质疑，自我评价这节课我们学习了什么？小数点位置移动引起小数大小的变化规律是怎样的？质疑：对今天的学习还有什么疑问吗？（培养学生敢于质疑，勇于创新的精神）评价：首先自评，学生对自己学得怎样，用什么方法学习，印象最深的内容是什么进行评介。接着可以生生互评或师生互评，教师重点表扬大部分学得好的同学或全班的同学，增强学生的自信心和荣誉感，使他们更加热爱数学。（五）作业布置：1、回忆一遍操作探索发现规律的整个过程，进一步培养学生良好的学习方法和习惯。2、预习97页，例2和例3，做书上98页练习第三题。

新人教版高中英语必修3Unit 5 The Value of Money-Reading and Thinking教学设计一
Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

解析：水是生命之源，节约水资源是我们每个居民都应有的意识.题中给出假如每人浪费一点水，当人数增多时，将是一个非常惊人的数字，100万人每天浪费的水资源为1000000×0.32＝320000（升）.所以320000＝3.2×105.故选B.方法总结：从实际问题入手让学生体会科学记数法的实际应用.题中没有直接给出数据，应先计算，再表示.探究点二：将用科学记数法表示的数转换为原数已知下列用科学记数法表示的数，写出原来的数：（1）2.01×104；（2）6.070×105.解析：（1）将2.01的小数点向右移动4位即可；（2）将6.070的小数点向右移动5位即可.解：（1）2.01×104＝20100；（2）6.070×105＝607000.方法总结：将科学记数法a×10n表示的数，“还原”成通常表示的数，就是把a的小数点向右移动n位所得到的数.三、板书设计借助身边熟悉的事物进一步体会大数，积累数学活动经验，发展数感、空间感，培养学生自主学习的能力.

光年是表示较大距离的一个单位, 而纳米(nanometer)则是表示微小距离的单位。1纳米= 米，即1米= 纳米。我们通常使用的尺上的一小格是一毫米(mm)，1毫米= 米。可见，1毫米= 纳米，容易算出，1纳米相当于1毫米的一百万分之一。可想而知，1纳米是多么的小。超微粒子的大小一般在1～100 纳米范围内，故又称纳米粒子。纳米粒子的尺寸小，表面积大，具有高度的活性。因此，利用纳米粒子可制备活性极高的催化剂，在火箭固体燃料中掺入铝的纳米微粒，可提高燃烧效率若干倍。利用铁磁纳米材料具有很高矫顽力的特点，可制成磁性信用卡、磁性钥匙，以及高性能录像带等 。利用纳米材料等离子共振频率的可调性可制成隐形飞机的涂料。纳米材料的表面积大，对外界环境(物理的和化学的)十分敏感，在制造传感器方面是有前途的材料，目前已开发出测量温度、热辐射和检测各种特定气体的传感器。在生物和医学中也有重要应用。纳米材料科学是20世纪80年代末诞生并正在崛起的科技新领域，它将成为跨世纪的科技热点之一。
大班社会教案：多彩的少数民族
活动准备： 幼儿前期经验、调查表、PPT等活动过程：一、讲讲知道的少数民族 价值取向：回忆已有的经验，引出内容。1.教师：最近我们正在研究一些少数民族，谁知道什么叫少数民族？你都知道哪些民族？请你们用好听的、有节奏的声音说说你知道的少数民族的名字。（这里你的要求是用好听的节奏说，那么用什么样的节奏呢，最好你先预设一个节奏，比如老师先有节奏的说一说？）2.出示地图（地图上标有代表56个民族标志）：刚才小朋友说了好多少数民族，看，它们就分布在我们伟大祖国的四面八方，除了小朋友说道到，你们看，还有（让幼儿简单知道一些其他的少数民族3.这么多的少数民族，你们知道一共有多少个吗？（用数字表示出来） 总结：哇！祖国真大啊，原来我们一共有56个民族了，每个民族都有它们不同的风俗习惯和特色，藏着好多好多有意思的秘密。
中班数活动：爱心礼物课件教案
活动目标：1、运用已有的数经验进行10以内的数数，初步感知数的守恒。2、通过倾听故事，体会孩子对母亲的爱。活动准备：课件《爱心礼物》、黑板两块、操作表格数份、红五星若干。活动过程：一、故事《大大和小小》导入二、大大选裙子（在贴一贴的游戏中初步感知物体不受大小、排列方式、疏密程度影响的守恒关系。）1、观察裙子（裙子有什么不一样？裙子上的数字是什么意思？）小结：这些数字是裙子上的编号，上面有数字1的说明是1号裙子。2、帮助大大选花最多的裙子送给妈妈，让孩子思考选择。3、贴一贴：你认为花最多的是哪条裙子？为什么？（孩子观察表格后再贴）4、讨论验证：（活动的关键，引发幼儿争论通过验证来解决问题）（1）到底是哪一条呢？你是怎么知道这条裙子上的小花是最多的？（2）产生解决办法（运用已有的数数经验）（3）小结：原来，裙子上的花是一样多的，你们用数一数的办法找到了正确答案，所以我们不能只看花的大小、排列方式来决定花朵的多少而是要用数数的方法。 三、小小选裙子（迁移运用，继续感知物体数量的守恒）1、帮助小小选花最少的裙子送给妈妈。（把五角星贴在相应的框里）2、填表格最后一格：裙子上花有几朵？3、验证小结：原来，裙子上的花是一样多的，所以我们不能只用眼睛看的办法，有时候我们的眼睛也会欺骗自己，我们就需要用数一数的办法才能知道正确的答案。

部编人教版六年级上册《只有一个地球》说课稿（一）
一、教材简析《只有一个地球》一课是小学语文六年级上册第六单元的一篇课文。《只有一个地球》在本单元占有很重要的位置。本文的训练重点，也就是本组课文的训练重点，是抓住文章的主要观点，体会文章所表达的思想感情。本文从人类生存的角度上介绍了地球的有关知识，阐明了人类生存“只有一个地球”的道理，说明了保护地球生态环境的重要意义。课文从宇航员在太空遥望地球时所看到的景象写起，引出了对地球的介绍，接着，从地球在宇宙中的渺小，人类活动范围很小，地球所用的资源有限而又被不加节制地开采，随意破坏等方面，说明地球面临着资源枯竭的威胁。然后，用科学研究成果证明当地球资源枯竭时，没有第二个星球可供人类居住，最后得出结论：人类的选择只有一个，那就是精心保护地球，保护地球的生态环境。
部编人教版一年级下册《一分钟》说课稿
《一分钟》是小学语文一年级下册第七单元的一篇课文。课文的主人翁是元元，讲他因多睡了一分钟，带来的是20分钟的迟到，一路焦急的等待和不停的叹息，是步行的辛苦和脸红的尴尬，是深深的后悔和宝贵的教训。以元元两次叹气为线索讲了他上学路上的不顺心，遇红灯，错过公交车，最终决定走路到学校的一个完整故事。结尾说他很后悔，以此引发思考，告诫小朋友们要珍惜每一分钟，养成良好的生活习惯。故事贴近生活，道理深刻。根据《全日制义务教育语文课程标准》，结合教材特点和学生实际，我拟定了以下四个教学目标：1、 会认“池、洗”等13个生字，会写“钟、元”等7个生字。2、 能正确、流利地朗读课文，在读、议、演中理解课文，在阅读中积累语言。3、 在读中体悟时间的宝贵，要做遵守纪律的好孩子，珍惜时间。4、 培养主动识字的习惯和合理运用时间的习惯。教学重点：正确、流利、有感情地朗读课文，体悟时间的宝贵。教学难点：识字、写字
部编人教版一年级下册《一分钟》（说课稿）
一、教材分析：课文以小学生喜爱的故事形式出现，内容较为通俗。主人公元元因为早上多睡了一分钟，带来的却是20分钟的迟到，是一路焦急地等待和不停地叹息，是步行的辛苦和脸红的尴尬，是深深的后悔和宝贵的教训。故事与学生实际生活联系十分紧密，教学中要引导学生联系自己的生活实际体验、理解课文内容，从中受到教育和影响。由于学生小，时间观念不强，对于如何珍惜时间缺乏感性认识。本文正是一篇十分优秀的文章。教学时要充分利用教材资源创设情境，在读中感悟，从中体会元元的焦急与尴尬，也使这件事成为宝贵的教训，促使每个学生都能对自己严格要求，珍惜时间、科学利用时间。
小学科技活动教案
针之所以能在水面上漂浮，是水的表面张力支撑住了针，使之不会沉下。表面张力是水分子形成的'内聚性的连接。这种内聚性的连接是由于某一部分的分子被吸引到一起，分子间相互挤压，形成一层薄膜。这层薄膜被称作表面张力，它可以托住原本应该沉下的物体。 后面的活动中，洗洁精降低了表面张力，针就浮不住了。 材料准备：一杯水、针、一小条面巾纸、洗洁精 活动过程设计： 一、提问，揭示课题： 1、在杯子里倒一杯清水，然后出示针，问：把针放在水面上，是沉还是浮? 2、学生猜测，然后实践操作。不管学生多么仔细，针总是会沉到杯底。 3、设置问题：有没有办法让针漂浮在水面上呢?
