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.

在全市医保基金飞行检查总结研讨会暨2024年飞行检查动员会上的讲话
同志们，通过飞检，基金监管的形式不容乐观啊。全市各定点医药机构要对照检查发现的问题，引以为戒，举一反三，健全内部医保管理制度，完善岗位职责，自觉规范医疗服务行为，为参保人员提供合理优质的医疗服务，切实履行好规范使用医保基金的主体责任，共同维护医保基金安全。我们医保局在今后的工作中也要进一步加强检查监督力度，加大检查频次，落实医保基金监督管理职责，继续加大飞行检查力度，深入开展打击欺诈骗保专项整治，严肃查处一批大案要案，严厉打击一批重大团伙，坚决曝光一批突出典型，巩固“不敢骗”高压态势。同时，强化大数据监管，构筑全社会监督防线，织密“不能骗”的天罗地网，完善基金总额预算、集采药品结余留用等政策，引导两定机构和医务人员自觉规范服务行为，推动构建“不想骗”的长效机制。规范医保基金使用行为，切实保障医保基金安全稳定运行，守护好百姓的“救命钱”。
学雷锋精神，创建文明校园说课稿
雷锋精神是什么？这一环节是让学生用简单的词语或句子概括。通过这一活动，让学生概括出雷锋精神的内涵：像无私奉献、乐于助人、为人民服务、勤俭节约、尊老爱幼、勤奋好学、干一行爱一行、言行一致等等都是雷锋精神的体现。我们少年儿童是中国的未来和希望，雷锋精神的发扬和光大，创建文明校园的任务就落在他们的肩上，所以在这里我还设计了为发扬雷锋精神，创建文明校园“我该怎么做”这样的问题，目的就是让他们一起行动起来，学雷锋做好事，并制作了“荣誉”旗，奖励身边的好人好事。活动延伸：这里我设计了一个角色游戏活动——我要义卖献爱心，这个游戏学生们表现得非常积极，他们收集了自己不要的小文具或小玩具，将他们拿到集市上去卖，卖东西获得的钱，捐给王奶奶的孙女，因为王奶奶的孙女生病了，无钱治病。我觉得这个游戏使学生们懂得，一个人只要有爱心，只要愿意去帮助别人，无论什么方式都行，而且在游戏活动中孩子们体会到了帮助别人是一件多么多么快乐的事呀。
小学数学人教版六年级上册《运用分数除法解决实际问题》说课稿
一．教材分析本节课是人教版六年级上册第38页例5，首先我对本节教材内容进行如下分析：本节课的教学设计力图体现“尊重学生，注重发展”，强调以学生为主体的学习活动对学生理解数学的重要性，本节教学内容分数除法中的解决问题，问题情境的数量关系表现为已知一个数的几分之几是多少，要求这个数，这样的的实际问题，与上一单元求一个数的几分之几是多少的实际问题，具有紧密的内在联系，即数量关系相同，区别在于已知数与未知数交换了位置，因此我有意识地采用多种活动方式，让学生理解知识的产生和发展的过程，尝到发现数学的滋味。 二．学情分析：我对我班学生也做了比较详细的分析，我班有13名学生，人数不多，但对数学知识的学习两极分化比较严重，大部分学生对数学学习有着浓厚的兴趣，但也有一部分学生与其他学生差异较大，对数学学习缺乏信心，积极思考的习惯有待于培养。因此在本节教学中，我关注更多的是用学生已有的知识经验激发学生的兴趣。
