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!

关于期末考试前国旗下讲话推荐
同学们、老师们：大家早上好！今天我演讲的题目是:“积极迎接考试，争取优异成绩 ”。时间跑得真得很快，开学的情景还历历在目，转眼间又将迎来我们的期末考试。以最佳的状态，争取优异的成绩，是我们共同的心愿。为了实现这个愿望，我认为我们应该做好以下四个方面的准备。第一、戒骄戒躁，安心学习。没有一个好的学习心境，我们就不可能正常地进行复习，复习的效率也不会高。在复习阶段，有些同学取得了好成绩，就自以为是，就骄傲了。却不知，这往往是最危险的时刻，因此奉劝那些同学，需要冷静，避免功败垂成。还有些同学因为一时成绩不理想，心理就烦躁不安了，那也是要不得的，考试就是一次机会，我们应该抓住机会，证明自己，超越自我。要知难而上，要有克服困难的信心和勇气。第二、珍惜时间，用心复习。期末考试是对一学期来所学内容的全面考查，它所复盖的知识点多，能力要求也更高更全。这就需要我们花更多的时间来复习和记忆，我们的老师都进行了精心的准备，科学的安排，我希望我们学生要珍惜这几天的时间，坚持不懈。

期末复习总动员---第19周国旗下讲话稿 亲爱的老师，同学们：大家早上好!时光如梭，岁月如歌，转眼间，我们一个学期的学习即将结束了!再过两 个星期左右，我们就要迎来本学期的期末考试。期末考试是我们一学期学习成果的展示，是所有同学摘取果实的时候。那么，我们应该怎样去做呢？首先，我们一定要珍惜时间。我们只要能够在老师的指导下，认认真真地听好每一节复习课，踏踏实实地做好每一道习题，仔仔细细地完成每一次作业，那么，你的成绩就一定会有明显的提高。请同学们抓紧点滴时间，暂时少玩一玩，回家后少看一会儿电视，全力以赴地投入到总复习中去。今日事，今日毕，千万不要抱有任何侥幸心理，不要等到拿到成绩报告单时才追悔莫及。其次，我们要全面复习不疏漏。一个学期中，我们学习的知识很多，我们要在老师的指导下，静下心来，扎扎实实地进行全面和系统的复习，要一个单元一个单元，一篇课文一篇课文有计划的复习。在全面复习的基础上，我们还要找准自己的薄弱点，抓住每门功课的关键点，每个单元的重点和难点，有目的地进行归纳、整理、训练。同时，我们还要讲究复习方法，复习一个知识点，就要真正掌握，还要学会运用，把课内外知识结合起来，举一反三，注重复习的效果。

老师们、同学们：大家上午好！还有一个礼拜的时间就要期末考试了，考试过后就是年假，老师、家长以及亲朋好友都在关注你的这次考试成绩，考试成绩的好坏也是你能否度过一个愉快假期的重要因素，所以，希望同学们认真对待这次考试。对于期末复习应该注意什么问题呢？在这里我向同学们提了几点建议，望大家做到以下六点：1、 上好复习课。每一节复习课都是经过老师精心设计的。在复习课中，老师必定和大家一起回顾每一类知识的重难点，对前面学过的知识进行浓缩梳理，所以不能错过任何一节复习课，大家要认真参与，不应在复习课上开小差出现跑神的现象。2、 敢于提问。如果感到自己哪方面的知识不过关，有疑问的一定要提出来，问同学、问老师、问家长，弄懂以后还要多练习两次。只有这样，才能及时有效地弥补自己的知识漏洞。3、 认真完成作业。复习期间，老师会根据知识的重难点，有计划地布置作业，有目的地练习巩固。因此，我们必须按老师要求，认认真真地做好作业，只有这样复习才能达到事半功倍的效果。4、 自我复习。

二年级迎接期末考试国旗下讲话
各位同学，各位老师，早上好!伴着清晨的缕阳光，我们又迎来了新的一天，新的一周。今天我讲话的主题是：以积极的态度迎接期末考试 。开学到现在已近一个学期了，四个月来，老师们克服了很多困难，认真地备课、上课、批改作业、辅导学生;我们同学认真地听课、按时完成作业、积极参加各项活动，确保了学校教学工作的顺利展开。一转眼，今天已经是第十八周的星期一了，下周的星期二将举行语文、数学的期末考试，星期三将举行英语的期末考试。期末考试是学校教学工作中的一件大事，它是评估一学期来教学质量和学习质量的一种重要手段，期末考试的学科成绩是衡量教师教学质量和学生学习质量的主要依据之一。因此全体师生思想上要高度重视期末考试考试，认真复习，作好充分准备，力争在期末考试中取得优异成绩，为此特向全体师生提出如下三点要求：1，要求全体老师要根据期末考试的特征，根据本学科的特点，结合学生的实际精心备好每一节复习课，认真上好每一节复习课，系统整理一学期来的知识体系，供学生复习使用。同时要做好基础薄弱学生和学有困难学生的思想工作，切实加强这些同学的辅导工作，做好考试方法的指导工作，激发他们的信心，努力使他们在原有的基础上有所提高。
3篇期末考试动员国旗下讲话稿
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。因为下周我们就要进行期末考试了。其实从上个星期开始，我们中就有许多同学已经制定了复习计划，并按计划开始复习了。今天，我不想谈关于复习方法或是复习内容之类的问题。今天，我想和大家说的是关于“自信心”的问题。有这样一句格言：“对自己说，我行!” 这虽是一句朴实无华的格言，但对一些人来说，要做到这一点却实在不容易。那么，是什么妨碍了你的自信，压抑了你的勇气呢?我想，有这么几点可以帮助你树立积极、乐观、自信的精神。一、避免使用否定自己的语言。“我不行。”“我是个没用的人。”“我很笨。”你是不是会时常说出这样的话?如果是的话，要知道，你是在进行一种负面的自我暗示，使自己的情绪充满失败感。也许你会说这是为了体现一种谦虚，但是，“累积暗示效果”会使你产生自卑。也会让听到你说话的人，认为你真的是个没用的人。所以，我们一定要避免使用否定自己的语言，要自信而理直气壮地说：“我行!”
