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!

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.

6月国旗下讲话稿：安全常记心中
敬爱的老师们、亲爱的同学们：大家上午好！我是三二中队的......我今天讲话的主题是“安全常记心中”生活中什么最重要？是安全。只有生命安全有保障，一切才会有意义。当同学们听到有关小学生意外伤害事故时，不知道你们想了些什么？那些血淋淋的教训无论发生在谁的身上，都会给家人和朋友带来沉痛的打击。安全问题关系到我们每一位同学，我们从小就应该牢固地树立安全意识，保护我们的人身安全。这里，我向全体同学发出倡议：一、路途安全方面1、上学、放学途中要遵守交通规则，未满十二周岁不允许骑自行车上学。2、途中不玩火、不玩水，不乘坐违规车辆。3、放学按时离校，不在校园、放学途中逗留，及时回到家中。不与陌生人交往，不接受陌生人馈赠的物品。
国旗下讲话：啊，中国心（老师稿）
青年朋友们：当你们听到《我的中国心》这支歌时候，难道你不陶醉在那优美的旋律里？难道不被歌曲所抒发的那种强烈的爱国情愫所感染？“……我的祖先早已把我的一切烙上中国印……”在歌声中，我想起了一个四五岁的小孩，他蹲在一边看着一张图纸，我和几个伙伴在旁边打排球。突然，球掉进了水沟里。“哎，这张纸给我擦球行吗？”“我才不呢！”我掏出一颗巧克力，说：“你把纸给我，这颗巧克力就归你。”他望望巧克力，又望望地上的那张纸——哦，这时候我才看到那是一张中国地图。他摇摇头。我故意追问了一句：“你不想吃吗？”“想。”“那你怎么不给我？”他扑闪着大眼睛，认真地说：“爷爷说：不能出卖祖国” 。热爱自己生于斯、长于斯的祖国。是中华民族世世代代的共同感情，这种感情一代连一代，缠绵不断。你看，这个幼小的心灵里，不是已经注进了真挚的爱国之情了么！啊，中国心！中国心！“长江，长城，黄山，黄河，在我心中重千斤……”
国旗下爱国讲话稿：祖国在我心中
同学们好:今天我向大家演讲的题目是“祖国在我心中”。我国是一个历史悠久、历经沧桑的文明古国。我国虽然历史悠久，但是在大家的心中有一段忘不掉的经历。抗日战争、虎门销烟、九.一八、七.七事变多历历在目。但我国的历史也有光辉璀璨的一面。是古人发明了汉字。很久以前，古人并不会写字、记事，有人想出了绳结记事法，但是太麻烦了。就有一位叫仓颉的人发明了甲骨文。在我国的文化史上那些诗人、文学家是不可缺少的。文天祥的《过零丁洋》是千古绝句;孟郊的《游子吟》歌颂了伟大的母亲;李白的《静夜思》表达了他的思乡之情。还有那些着名的文学家。司马迁的《史记》被鲁迅称为‘史家绝唱，无韵之离骚’
关于中考冲刺国旗下讲话稿
同学们：当早晨的第一缕阳光洒向大地， 我们又迎来了新的一天，新的一周。这一周是最后冲刺的一周。因为下周初三就要中考，其他年级也就要进行期末考试了。我们中许多同学已经制定了复习计划，并按计划开始复习了。关于复习方法或是复习内容之类的问题。我们的老师会给我们详尽而有针对性的指导，许多同学也积累了一套适合自己的复习经验，都很有效果。今天，我想和大家说的是关于“自信心”的问题。同学们，在我们的生活中，你有时会不会这样想：“他太厉害了，我肯定比不过他。”“这件事我无论如何也干不了。”“哎呀，我不是读书的料。”“我对这件事太没有把握了”等等。一件事在没做之前，你就从心理上自己打击自己，从开始就不抱成功的希望，这种自责自卑比其他任何因素更能破坏你的学习，你的生活，使你不能变得越来越优秀，也快乐不起来。
关于国旗下讲话稿：备战中考
同学们、老师们：大家好！今天我演讲的题目是《备战中考》。光阴似箭，日月如梭。转瞬间，我们在上会中学三年的初中生涯即将结束，等待我们的将是竞争激烈的中考。今天是4月23号，离中考仅有52天，可谓时不我待，形势紧迫。我们已经看到了那中考战场上燃起的硝烟，闻到了剑拔弩张的火药味。再过52天我们就将迎来人生的第一次机遇，更是人生的第一次挑战！52天，是短暂的，如果你浑浑噩噩，你必将一无所获而丧失人生发展的第一次机遇；52天也是漫长的，如果你全身心投入学习，在每天的艰辛与劳累中享受点滴成功的喜悦，那么你就抓住了人生发展的第一次也是最重要的一次机遇，跨上了人生竞争的第一个台阶，展示在你面前的将是更广阔的天地和更美好的前程!三年的艰辛与付出，一千个日日夜夜的奋斗与追逐，为的都是同一个梦想：“考个好成绩，上个好高中”。
关于高中期末考试国旗下讲话稿
老师们，同学们：我国旗下的讲话的主题是《向期末考试做最后的冲刺》时光如梭，岁月如歌，不知不觉，紧张、忙碌而又充实的一个学期即将结束。本周四、五及下周一就要进行期末考试了。大家可以算算距考试还有多长时间，俗话说，“临阵磨枪，不快也光”,因此，请同学们抓紧时间，劳逸结合，认真进行复习。我希望同学们深刻领会有关内容，搞好复习，考出好成绩。下面我给同学们提几点建议。一、正确认识，高度重视。期末考试不仅是对同学们一个学期以来学业成果的一次盘点，更是对每个人综合素质的一次挑战，是对同学们自信心、自觉性、意志力的一次考验，也是同学们对老师辛勤工作予以回报的时刻。希望同学们克服过于紧张、焦虑的情绪，沉着冷静，以从容自信的态度面对期末考试。我不能要求每个人都成为优胜者，但我希望大家做一名追求进步、超越自我的勇敢者。希望同学们能够抓住机会，充分展示自己，在这收获的季节摘取胜利的果实。
高中学生国旗下讲话稿开头
演讲稿频道《高中学生国旗下讲话稿开头》，希望大家喜欢。亲爱的老师、同学们，大家早上好!很荣幸能在这阳光明媚的早晨，在亲切而壮严的国旗下做演讲。今天我演讲的题目是“让运动成为习惯”。我国古代著名的医学家华佗认为：生命在于运动;而民间也有更为直白的俗语说道：人勤病就懒，人懒病就勤。说得其实是一个意思，就是健康的身体需要运动来保证，而人生最大的财富正是健康。所以，要想拥有这笔财富，最佳的方法就是：让运动成为习惯。如今，美丽的校园正给我们提供了这样的条件，宽广的绿茵场给了大家一个充分展现自我的空间。每天下午，放下手中的功课，跑上两圈，挥洒一些汗水，倦意便顿时消失，不仅达到了劳逸结合的效果，也丰富了我们的课余生活。若长期坚持下去，必将使我们的体魄有所增强，从而有利于我们以更好的状态投入学习活动中去。然而，有些同学则认为体育锻练是浪费时间，认为分秒必夺的读书学习才是硬道理。他们无论早晨、下午甚至是体育课上都捧着书抓紧学习。他们牺牲的是运动的时间，得到的是短期内学习成绩的提升。
高中新学期开学国旗下讲话稿
尊敬的老师们、亲爱的同学们：大家好!在新学期的开学升旗仪式上，首先请允许我向刚安排到我们学校的新老师、新同学表示最热烈的欢迎!过去的一学年，我们学校在全体师生的共同努力下，学校各方面的工作稳步前进，教育教学方面取得了优异成绩，学校的面貌焕然一新。刚刚过去的这个暑假，虽然酷热，但确实令人感到愉快、难忘而有意义。同学们在假期中合理的休息、愉快的活动、刻苦的学习，努力做到寒假中学校的要求;在老师和家长的帮助下，大家踊跃开展丰富多彩的有益的活动;到外地开拓视野，增长知识;还不断的学习课外书籍等等，这一切真让人感到高兴!现在，同学们面对徐徐升起的五星红旗，你们在想什么呢?作为一个小学生，如何使自己成为家庭的好孩子、学校的好学生、社会的好少年呢?将来如何更好地适应新形势的需求，把自己塑造成为符合时代发展的、能为社会作出贡献的合格人才呢?
高中生母亲节国旗下讲话稿精选
为大家收集整理了《高中生母亲节国旗下讲话稿精选》供大家参考，希望对大家有所帮助！！！“妈妈”，这是一个多么朴实而又倍感亲切的称呼。“妈妈”，这是一个多么简单而又意味深长的字眼。妈妈，不但给了我生命，而且给了我无私的爱。母亲的爱是博大的爱，母亲的爱是无私的奉献。母亲的爱能容高山，母亲的奉献能填平大海。母亲的爱彼此相通，如同山峦起伏相连。世上的山峰纵有万千，比不上母亲的宽广胸怀。妈妈，您知道吗？每当我看到您为我忙碌的身影，抚着您头上的几丝白发，摸着您手里的茧，我就有好多话想跟您说。但是，当我站到您的面前，我却又不知道该从何说起了。今天，在这封信里，我想说出我想说的话，表达我对您的感激和深深的爱。
高中“向国旗敬礼”国旗下讲话稿
老师、同学们：大家好早上好！我是来自高三（7）的卢XX，两年前，因新生军训的优秀表现，我有幸成为一名学校升旗队的护旗手。今天很高兴能代表学校升旗队的所有成员在此发言，我国旗下讲话的题目是“向国旗敬礼”。同学们不知是否知道或是记得，XX年6月18日，由20国领导人参加的G20峰会在墨西哥洛斯卡沃斯开幕。在各国领导人合影时，主办方用国旗贴纸放在地上表示各国领导人站的位置。合影完毕，领导人散去，脚下的国旗被踩来踩去，无人理会。而中国国家主席胡锦涛弯腰捡起中国国旗贴纸，细心地收了起来。这一举动，让在场的世界各大媒体竞相报道，被世人传颂，各国人感动并深受教育。胡锦涛主席对国旗的尊重和爱护，充分体现了他深厚的爱国情怀，说明他作为国家主席，心中时刻装着国家和人民，始终把国家的尊严，人民的利益放在崇高的位置，不容轻视、不容践踏、不容侵害。五星红旗作为中华人民共和国国旗，是中华人民共和国的标志和象征。一个人对待国旗的态度，真实的体现了他对国家的情感，尊重和爱护国旗，是公民爱国情感的自然流露，更是法律赋予每个公民的职责。“爱国是文明人的首要美德”。“做人最大的事情是什么呢？就是看他是否知道怎样爱国”。
高中开学典礼国旗下讲话稿
亲爱的老师们、同学们，大家好。我是XX届的洪超。今天很高兴可以重返校园，和大家分享一下自己高中阶段的心得。我代表所有XX届学生向通河中学勤勤恳恳为我们奉献的各科老师、向高瞻远瞩的校领导还有为我们服务的校务人员表达深深的感激。三年前，接到通河中学的录取通知书的时候，我曾经为没有进入一所重点中学感到十分失落。但是，在通河中学的三年，我感受到这座年轻的学校蓬勃的生机，也逐渐转变原先的看法。我时常想，倘若我校有那些重点中学一样悠久的历史，我们绝对不会比它们差。就像，在通河的最后一年，我校获得了区重点的称号。一个又一个荣誉，让我深刻体会了往届学长挂在嘴边的那句：今天我为通河自豪，明天通河为我自豪。高中，是通向大学的最后一处碉堡，也预示相当难熬的一场持久战。一言以蔽之，这个时段需要我们广泛参与学校的活动锻炼自己的能力，也需要在考场拼成绩、拼心态、拼体力。
