This happens because the dish soap molecules have a strong negative charge, and the milk molecules have a strong positive charge. Like magnets, these molecules are attracted to each other, and so they appear to move around on the plate, taking the food coloring with them, making it look like the colors are quickly moving to escape from the soap.Listening text:? Judy: Oh, I'm so sorry that you were ill and couldn't come with us on our field trip. How are you feeling now? Better?? Bill: Much better, thanks. But how was it?? Judy: Wonderful! I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool. I wish I could have gone with you? Judy: I know, but we can go together this weekend. I'd love to go there again!? Bill: That sounds like a great idea!

The grammar of this unit is designed to review noun clauses. Sentences that use nouns in a sentence are called noun clauses. Nominal clauses can act as subject, object, predicate, appositive and other components in compound sentences. According to the above-mentioned different grammatical functions, nominal clauses are divided into subject clause, object clause, predicate clause and appositive clause. In this unit, we will review the three kinds of nominal clauses. Appositive clauses are not required to be mastered in the optional compulsory stage, so they are not involved.1. Guide the students to judge the compound sentences and determine the composition of the clauses in the sentence.2. Instruct students to try to learn grammar by generalizing grammar rules, controlling written practice, and semi-open oral output.3.

人教版新课标高中物理必修1力学单位制教案2篇
一、教材分析在初中阶段，物理量单位的学习是学生较为困惑的问题之一。前面关于1N的规定给学生的印象总好像是有些随意。尤其是牛顿、帕斯卡、安培、伏特、焦耳、瓦特等单位的规定。使得学生感动物理太复杂。事实上，只有把单位制放在整个物理学框架中加以认识，并且知识有了一定的积累。经历了充分的学习过程后才能体会物理量单位的命名和使用规则。体会到其中对一些单位进行规定的合理性和方便特征。物理学单位中，有很少几个基本物理量，它们的单位就是基本单位。在进行了这种选定之后，其它物理量的单位就是根据它的定义式，有所选择的其他物理量的单位共同确定的。国际单位制的建立和使用，不仅方便了国际间的交流，也逐渐成为科学研究中计算和运用的一种规范约束。中学生应该注意学习，逐步习惯，在记录、表达和计算中规范使用。二、教学目标（一）知识与技能1．了解什么是单位制，知道力学中的三个基本单位；2．认识单位制在物理计算中的作用

北师大初中数学九年级上册利用相似三角形测高2教案
[想一想]同学们经历了上述三种方法，你还能想出哪些测量旗杆高度的方法？你认为最优化的方法是哪种？思路点拔：1、如果旗杆周围有足够地空地使旗杆在太阳光照射下影子都在平地上，并能测出影子的长度，那么，可以在平地垂直树一根小棒，等到小棒的影子恰好等于棒高时，再量旗杆的影子，此时旗杆的影子长度就是这个旗杆的高度．2、可以采用立一个已知长度的参照物在旗杆旁照相后量出照片中旗杆与参照物的长度根据线段成比例来进行计算．3、拿一根知道长度的直棒，手臂伸直，不断调整自己的位置，使直棒刚好完全挡住旗杆，量出此时人到旗杆的距离、人手臂的长度和棒长，就可以利用三角形相似来进行计算．等等．第四环节 课堂小结1、本节课你学到了哪些知识？2、在运用科学知识进行实践过程中，你是否想到最优的方法？3、在与同伴合作交流中，你对自己的表现满意吗？第五环节 布置作业，反思提炼

部编版语文九年级上册《酬乐天扬州初逢席上见赠》说课稿
二、说学情学生是课堂的主体，教师应本着“因材施教”的理念结合学生的基本情况进行备课。九年级的学生已经有了较好的积累，基本词汇、常见修辞等等都有了较为自如的把握。对于诗歌这种文体，他们已接触过很多年。但由于对诗歌这种文体的情感把握还不够精准到位。此外，这一阶段的学生已经有了一定的写作和口语表达能力，我将在本文的教学过程中设置口语表达及写作的环节，学生可通过实践进一步强化这方面的能力。三、说教学目标因此，基于教材和学情，我从课程标准中“全面提高学生语文素养”的基本理念出发，设计了以下三个维度的教学目标：1.知识与能力：结合注释解释全文大意，并能初步体会是中蕴含的情感。2.过程与方法：通过有感情地朗读、独立思考、讨论、对文章中关键内容的探究等过程，体会文章语言的优美和表达的精妙。3.情感态度与价值观：懂得诗人重新投入生活的意愿及坚韧不拔的意志。

骑自行车的交通安全 我国是自行车大国，许多年满12周岁的同学都骑自行车上学，骑自行车应注意哪些问题呢?下面请听一名同学朗诵《安全骑车歌》。 安全骑车歌 同学们骑自行车，听我唱段安全歌。 车铃好使闸要灵，有了情况车能停。 上街注意看信号，千万不要冒险行。 信号就是指挥员，骑车第一讲安全。 看见红灯快刹闸，该等多久等多久。 绿灯亮了才能行，安全通行不争抢。 十字路口人车多，左右观察听八方。 骑车带人危险大，攀扶车辆更可怕。 中速骑车靠右侧，分道行驶路畅通。 骑车拐弯要示意，不能猛拐一溜风。 手拉手儿把肩摸，十有八、九要撞车。 双手离把更不行，撞上汽车命归西。 骑车不走一条线，东摇西摆像醉汉。 不定哪天出事故，头破血流住医院。 驮载东西别超宽，超高超长也危险。 骑车让让讲安全，事情虽小不平凡。
开展“奋进网上祭英烈”主题活动心得体会通用范本
清明时节，祭祀先祖、缅怀逝者，一直是中国人寄托哀思的重要方式，也是这个传统节日的主要内涵。此举有利于倡导孝亲理念，对于弘扬传统文化、传承民族精神，具有十分积极的意义。但同时也要看到，近年来，一些地方常常因祭扫活动造成交通拥堵，加之不文明的祭扫陋习，燃烧香烛纸钱、随地乱扔垃圾等问题频频出现，不但扰乱公共秩序、造成环境污染，而且极易引发交通事故、墓地火灾等严重后果。特别是疫情期间，如果扫墓者大量聚集，防控风险必然突增。从这个角度看，暂缓举办集体共祭、骨灰撒海、公益性安葬仪式等群体性活动，暂缓开放不具备疫情防控条件的骨灰存放场所祭扫服务，大力倡导“云祭扫”“预约祭扫”，既有利于降低疫情传播风险，也能激荡社会文明新风，提升社会文明程度。
清明缅怀革命先烈主题活动心得体会范文精选
英烈们虽打下了江山，但他们的事业还没有完成。与发达国家相比，中国依然贫穷落后。为了圆民族的强盛梦，让先烈的理想变成现实，每个炎黄子孙责无旁贷地担负起建设富强祖国的历史重任。是的，目前中国还穷，正因为如此，才需要我们来开拓建造一个美丽的家园。美国曾经也很穷，美国牛仔当年开发西部时也绝没有可口可乐，但他们的后代没有抱怨、观望，更没有逃避和背叛。靠着一代又一代人的努力，他们富强起来了。清贫的中国正需要这样的硬气，继承先烈遗志，实现先烈遗愿，我们唯有卧薪尝胆，自强不息。谁不想自己的祖国日益强大呢?谁不想在走出国门时可以骄傲地称自己是中国人呢?祖国是民族的根，爱国是民族的魂。世界上任何一个伟大的民族都把爱国作为自己精神的支信和力量的源泉。
