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!

9月国旗下讲话《贺重阳，敬老人》
老师们、同学们，早上好！今天我国旗下讲话的题目是《贺重阳，敬老人》。金秋送爽，丹桂飘香。今天是农历九月初九，是我国的传统节日——“九九”重阳节。“九九”与“久久”同音，含有长久、长寿之意。人们对这个节日，历来有着特殊的感情，唐诗宋词中就有不少贺重阳、咏菊花的诗词佳作。尊老、爱老、敬老、助老，是中华民族的传统美德，是先辈传承下来的宝贵精神财富。古往今来，我国流传着许多敬老爱老的名言和故事。孔子说，做子女的能够活下来，是因为有父母的养育。孟子说，“老吾老以及人之老”，意思是不仅要尊敬自己的老人，还要尊敬社会上所有的老人。还有花木兰代父从军、陈毅探母等感人肺腑的故事。20年前的1989年，我国把每年的农历九月初九定为“老人节”，传统的重阳节被赋予了新的含义，成为老年人的节日。人人都会老，家家有老人。
国旗下的讲话：做一个有修养的人
每个人都要努力提高自己的道德思想修养，无论你是谁，无论你年龄大小，无论你身份高低贵贱，只要你愿意做出努力，你就一定可以成为一个有修养的人。相反，即使你有着尊贵的社会地位，即使你取得了骄人的成绩，也不见得你就是一个有修养的人，因为，修养并不等于金钱、地位、才智、荣誉。那么，怎样才能具备良好的道德修养呢？第一，要有爱心。俗话说“送人玫瑰，手有余香”，爱亲人、爱老师、爱朋友，甚至是爱那大自然中的一草一木，当你对生活中的一切充满爱心，而由此你获得了心境的开阔和精神的愉悦时，你才能体会出这句话所包含的深刻哲理。第二，要有责任心。范仲淹说过：“先天下之忧而忧，后天下之乐而乐”，这是古代贤人士大夫责任心的典范表现；周恩来说过“为中华之崛起而读书”，这是我们当代伟人以天下兴亡为己任之心声。对于我们而言，同样也应该具有这种胸怀天下、放眼未来的豪情壮志，以及以天下为已任的责任感。但“一屋不扫，何以扫天下”，要想承担起大的责任，我们必须有能力承担起小的责任，我们敢不敢说“学校兴亡，我的责任”、“班风好坏，我的责任”、“教室卫生没搞好，我的责任”，如果对这些你不管不问，我们凭什么相信你有崇高的思想；如果连这些小的责任你都不能负，我们凭什么相信你能担负得起大任呢？
国旗下的讲话：想做校园的主人
国旗下的讲话：想做校园的主人同学们，我在平常的一天之中， 经历了这样几个场景，请大家与我一同看看：场景一：天还未亮，水声便随着某位同学的“勤奋”早起而响了起来。因昨晚室友的挑灯夜战而未睡好的我在乒乒乓乓的声响中无奈起身，精神不振地去教室。场景二：清晨的空气格外清新，某位老师夹着课本去上课，路过教学楼时，被一杯从天而降的水浇走了好心情，无奈地转身赶回家换衣服。场景三：下了早读的同学蜂拥而出，三五成群的吃着早饭在校内、外走动着谈笑风生，在校外白色垃圾也随着同学们的足迹几乎遍地都是。在嘈杂的人群中，一个患了小儿麻痹症的中年男人一瘸一拐的默默地捡着垃圾。
关于做有道德的人的国旗下的讲话
我们要做有道德的人“道德”一词由来已久，早在两千多年以前，我国古代的著作中就出现了“道德”这个词语，“德”指内心的情感或者信念，用于人伦；“道”则指人的本性，品德，儒家认为，“德”包括忠、孝、仁、义、温良、恭敬、谦让等，道家则以为所谓天地万物这自然为“道”，而各种事物所得之自然为“德”，对人而言，便是品德，从中国儒家的创始人，伟大的思想家，教育家孔子开始，千百年来人们就一直重视道德问题。在现实生活中，经常有类似损人不利己的事情发生，比如上车，购物不排队，大家挤得难受；比如地铁列车和电梯开时堵在门两边，挤得里面的人出不来；又比如不守交通规则，造成交通堵塞或车祸，损人利己这方面例子太多了，大到盗窃、诈骗、谋财害命，小到逃票、偷撕别人邮票，在借的书上（特别是公共图书馆里借的书）乱画，偷撕公共图书杂志，在图书管聊天，在公共场合抽烟等。
关于自信人生的国旗下的讲话
自信演绎人生的精彩尊敬的老师、亲爱的同学们：大家早上好！很荣幸能代表高234班作国旗下讲话，我演讲的题目是《自信演绎人生的精彩》。人生， 是一场战斗的过程，时而平稳顺利，时而坎坷残酷，谁也不能卜知自己的命运，要想前进，要想成功，自信是必备的，人，只有自信，才能实现自己的理想，同时，人生又像一痤险峻的山峰，只有自信地地向上攀登，才能无限风光尽览眼底。自信是成功的秘诀，参透了自信的真谛，就算是已定的事实，也有翻身的希望，自信是一种力量，一种潜在的、可贵的、强大的力量，有了它，就可以干出一番惊天动地的伟大事业来，自信是做人的原则，一个人不可能事事顺利，不管遇到什么困难，不管经历多少失败，都努力去战胜困难，要像那无所畏惧的苍松一样，傲然挺立，自信是一种拥有，一股勇气，就是凭借着这股激情，我们才能开拓自己的人生道路，尽情描绘明日的七彩世界。
3月关于人的品质国旗下讲话
3月11日国旗下讲话做人的品质 人，一撇一捺，写起来容易做起来难。我们要经常性地思考：我要做什么，我在做什么，我做得怎样，我要成为怎样的人。做怎样的人，一百个人可能会有一百种答案，但在每一个答案的背后都有一个基点，那就是要做一个有品质的人。人不能没有“品”。没有“品”，就会与现实脱节，与良心相违背。人品是开展个人生命价值的关键，有品胜过有学；有德胜过有才，所以做人要有品格、做事要有质量、生活要有品味----有“品”才能彰显处世态度的合理性、道德性，才能创造生活的多样性。我们在日常生活中，大都只重视所谓的民生必需品、健康补给品，甚至有各种的医疗备用品等等。其实，在人生的另一个精神层次上，尤其需要有各种“营养品”，例如：礼貌是必需品：有的人言行举止总是莽莽撞撞、冒冒失失，弄得人家难以忍受，还自以为是无拘无束、洒脱自在。殊不知这是无知、幼稚的行为。礼貌是做人的必需品，有礼才能让人又敬又爱。
国旗下讲话 争做校园文明人倡议书
老师们,同学们:早上好!今天我话的题目是《争做校园文明人倡议书》.同学们,新学年,新气象,我们的校园处处洋溢着积极向上的气氛,学校无时无刻不在发生着日新月异的变化.身为北门里小学的一分子,我们又怎能不为此自豪和欢呼是的,一直以来,我们北小的领导和老师们默默工作,无私奉献,努力为同学们营造优美的校园环境,创造良好的学习条件.学校一天天发展,环境一天天改善,可以说是一天一个台阶.但是,同学们想过吗学校的发展,光靠老师的付出是远远不够的,需要你,我,他,大家的共同努力.你一言,我一行,塑造出北小文明,高尚的形象,每一位少先队员的举止言行展现的正是学校的品味,关系着学校的荣辱.然而,就在这块美丽的校园中,时常会出现一些不和谐的音符,总有一些令人不满意的现象出现.我们不难看到,清扫刚结束后的校园,就有我们同学扔下未喝完的牛奶袋,面包纸;在整洁的操场,有我们同学丢的纸屑,塑料袋;在书声琅琅的课堂上,有的同学却精神萎靡不振;在安静无声的自习课时,有的同学却在叽叽喳喳甚至高声喧哗;在庄严肃穆的升旗仪式上,有的同学却左顾右盼,窃窃私语.还有一些同学说脏话,争吵,打架,搞不团结,影响了学校形象和周围同学.以上这种种现象,不仅严重违反了小学生日常行为规范,而且也破坏了学校为我们提供的优美和谐的育人环境,与我们学校礼仪教育的主流不相符.本学期一开学,学校便把第一个月定为"德育工作月",把第一周定为"行为习惯养成周",并在全校启动"争做校园文明人"活动.
国旗下讲话：《当诚信人，做诚信事》
老师们、同学们：大家好！今天国旗下讲话的主题是：当诚信人，做诚信事。诚信是什么？农民说，诚信是秋天里结出的丰硕果实；工人说，诚信是辛勤劳作下生产出的质高价优的产品；老师说，诚信是师生间白玉般纯洁的感情；简而言之，诚信是个人的立身之本，民族的存亡之根。中国古代有这样一个故事：一个皇帝要选一个继承人，他发给王国内每个孩子一粒花种，并承诺说谁能种出最美丽的花，就选谁当国王。 评选时间到了，成千上万的孩子都端着漂亮的鲜花前来参选，只有一个叫杨平的男孩端着空无一物的花盆前来。但最后他被选中了。这是为什么呢？难道皇帝失信了。不，因为孩子们得到的花种其实都已被蒸过，根本不可能发芽。这次测试不是为了发现最好的花匠，而是要选出最诚实的孩子。
国旗下讲话：《书籍使人变得幸福》
各位老师、各位同学：早上好！今天国旗下讲话的题目是《书籍使人变得幸福》。有人说：“读书足以怡情，足以博彩，足以长才”，使人开茅塞，除鄙见，得新知，养性灵。因为书中有着广阔的世界，书中有着永世不朽的精神，虽然沧海桑田，物换星移，但书籍永远是新的。世纪老人冰心说过：“读书好，好读书，读好书。”这是一句至理名言。读一本好书，可以使心灵充实，使之明辨是非，使人有爱心和文明行为、礼仪规范；而读一本坏书，则使人心胸狭窄，使人不知羞耻，使人自私残暴。有这样一个故事，俄国的罗蒙诺索夫小的时候，最希望得到一本书，他是渔民的儿子。白天，他跟父亲打鱼，晚上，躲在板棚里看书。有一天，罗蒙诺索夫和父亲在海上打鱼，忽然，一阵狂风，大海掀起了巨浪，船上的帆篷被吹落了，情况十分紧急。他不顾一切，沿着摇晃的桅杆爬上去，很快把吹落的帆篷扎结实了，渔船恢复了平稳。
国旗下的讲话之——做一个文明之人
尊敬的各位领导、老师们、亲爱的同学们：早上好！今天我讲话的题目是《做一个文明之人》。在这里先给大家讲两个事例：第一个事例：新加坡是个以英语为通用语言的国家，据说他们的公共场所的各种标语大多是用英语书写的。但其中的一些涉及文明礼貌的标语，如“不准随地吐痰”、“禁止吸烟”、“不准进入草坪”等却用中文书写。这是为什么呢？人家回答：因为有这些不文明行为的大数是中国大陆的游客。为此，到新加坡考察的一位中学校长语重心长地说：不文明行为也是国耻。第二个事例：据中央电视台报道，国庆节后的天安门广场，随处可见口香糖残迹，显得格外刺眼，40万平方米的天安门广场上竟有xx万块口香糖残渣，有的地方不到一平方米的地面上竟有9块口香糖污渍，密密麻麻的斑痕与天安门广场的神圣和庄严形成了强烈的反差。
国旗下的讲话：做一个有道德的人
国旗下的讲话：做一个有道德的人老师们、同学们：大家上午好！今天我讲的题目是《做一个有道德的人》。意大利诗人但丁曾说过：“一个知识不健全的人，可以用道德来弥补，而一个道德不健全的人，却难以用知识来弥补。”上下五千年以来，道德一直是我们华夏儿女的宝藏。道德，是一种美德，是一种财富，更是一种智慧。道德源自于我们的内心，有了道德感，自己做出的事情自然就不会错。做好事，不是为了得到谁的表扬，得到怎样的荣誉。真正的道德，发自内心，你对社会，对每个人的爱，就是一份珍贵的道德。文明很小很小，但是只要每一个人都做文明的好事，就能使社会文明迈出一大步。一件小事很小很小，但是用处却很大很大。每一份文明就是一份力量，无数文明在一起就会产生一种无与伦比的力量，这种力量如破土的小苗，在每一个人的心里萌发。
关于掌握人生的国旗下的讲话
自己的人生掌握在自己的手中平庸的人总是有一种幸灾乐祸的心理，因为成功者总是给他们强有力的刺激，他们总是期望成功者能够功败垂成，沦为和他们一样的平庸。然成功者恰恰是这样一种心理素质：那就是宠辱不惊，镇定沉着。他们的人生之所以精彩，就在于他们不轻易地受到无关的事情的干扰，认真地走好人生的每一步，没有人能够让他们轻易失足。一位举世闻名的走铁钢索高手，正准备迎接面对自己人生当中一次最重要的挑战——在钢索上横渡加拉大瀑布。这位走钢索专家，不知道能否顺利地完成这一次的表演，成天忐忑不安，情绪上烦燥异常，给自己造成极大的困扰，经过热心朋友的建议，他找到了一位极负盛名的预言家，请预言家为他预测这一次是否得以顺利走完全程。
