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.

小学数学人教版一年级上册《认识图形（一）》说课稿第二课时
尊敬的各位评委、各位老师，大家好，我今天说课的内容是九年义务教育人教版小学数学一年级上册第四单元《认识图形》的第一课时——认识图形。下面我将从说教材、说教法与学法、说教学过程和说板书设计这四方面来谈谈我对本课的教学设想。一、说教材： 1、教材分析 首先我对本教才进行简单的分析，课程标准把空间与图形作为义务教育阶段培养学生初步创新精神和实践能力的一个重要的学习内容。《认识图行》是本册教材《认识图形》的起始课，旨在认识长方体、正方体、圆柱和球这些立体图形，认识这几种图形有助于发展学生的空间观念，培养学生初步的观察能力，动手操作能力和交流能力。 2、说教学目标 依据一年级学生的心理特点和的认知能力，我确定了以下教学目标： 1、知识与技能：通过观察操作，初步认识长方体，正方体，球和圆柱体。 2、过程与方法：在观察、操作、比较等活动过程中，培养学生抽象、概括、实践、创新能力，建立空间观念。

问题1. 用一个大写的英文字母或一个阿拉伯数字给教室里的一个座位编号，总共能编出多少种不同的号码？因为英文字母共有26个，阿拉伯数字共有10个，所以总共可以编出26+10=36种不同的号码.问题2.你能说说这个问题的特征吗？上述计数过程的基本环节是：（1）确定分类标准，根据问题条件分为字母号码和数字号码两类；（2）分别计算各类号码的个数；（3）各类号码的个数相加，得出所有号码的个数.你能举出一些生活中类似的例子吗？一般地，有如下分类加法计数原理：完成一件事，有两类办法. 在第1类办法中有m种不同的方法，在第2类方法中有n种不同的方法，则完成这件事共有:N= m+n种不同的方法.二、典例解析例1.在填写高考志愿时，一名高中毕业生了解到，A,B两所大学各有一些自己感兴趣的强项专业，如表，

当A,C颜色相同时,先染P有4种方法,再染A,C有3种方法,然后染B有2种方法,最后染D也有2种方法.根据分步乘法计数原理知,共有4×3×2×2=48(种)方法;当A,C颜色不相同时,先染P有4种方法,再染A有3种方法,然后染C有2种方法,最后染B,D都有1种方法.根据分步乘法计数原理知,共有4×3×2×1×1=24(种)方法.综上,共有48+24=72(种)方法.故选B.答案:B5.某艺术小组有9人,每人至少会钢琴和小号中的一种乐器,其中7人会钢琴,3人会小号,从中选出会钢琴与会小号的各1人,有多少种不同的选法?解:由题意可知,在艺术小组9人中,有且仅有1人既会钢琴又会小号(把该人记为甲),只会钢琴的有6人,只会小号的有2人.把从中选出会钢琴与会小号各1人的方法分为两类.第1类,甲入选,另1人只需从其他8人中任选1人,故这类选法共8种;第2类,甲不入选,则会钢琴的只能从6个只会钢琴的人中选出,有6种不同的选法,会小号的也只能从只会小号的2人中选出,有2种不同的选法,所以这类选法共有6×2=12(种).因此共有8+12=20(种)不同的选法.
第二周国旗下讲话稿：时代的呼唤
同学们好！寒假刚刚过去，新的学期又开始了。不知大家还记不记得2月11日那天，对于很多国人来说，那是再平凡不过的一天，但对于很多科学家来说，甚至对我们整个人类来说，它实在是值得载入史册的一天。北京时间XX年2月11日23:40左右，美国加州理工学院、麻省理工学院以及“激光干涉引力波天文台（LIGo）”的研究人员在华盛顿举行记者会，宣布他们利用LIGo探测器于XX年9月14日探测到来自于两个黑洞合并的引力波信号。大家还记得XX年底的科幻大片《星际穿越》吗？电影快结尾时，主人公库珀身处一个五维时空中，为了将从黑洞中心所提取出来的信息传递给身处四维时空的女儿墨菲，人为地制造引力波效应，最终成功将信息传递，从而解救了人类。以目前物理学家的认识来看，引力波是唯一一种可以在不同维度传播的波。著名理论物理学家斯蒂芬·霍金说：“引力波提供了一种人们看待宇宙的全新方式。”是的，人类从此拥有了新的宇宙感知力。当400年前伽利略第一次将亲手制作的望远镜指向夜空时，人类开始用眼睛欣赏宇宙的瑰美，而今天，人类聆听到了来自浩瀚宇宙的第一个美妙音符。

人教部编版语文八年级上册一着惊海天—目击我国航母舰载战斗机首架次成功着舰教案
2012年9月25日被称作辽宁舰的中国航母，是在苏联时期乌克兰黑海造船厂建造的“库兹涅佐夫元帅级”航空母舰次舰“瓦良格”号的基础上续建的。1991年12月苏联解体时，该航母已完工约70%，后来由于种种原因，俄罗斯海军取消了订单，这艘即将完工的航母被迫停产，随之报废。1998年4月，澳门创律旅游娱乐公司通过竞标，以2000万美元买下几乎拆成空壳子的“瓦良格”号航母。2005年4月“瓦良格”进入大连造船厂，由政府接管。此时的“瓦良格”只是一个锈迹斑斑的钢铁空壳，所有武器、电子系统均已被拆除或者破坏。中国海军准备在“瓦良格”的原型上进行续建，俄罗斯却不肯出让阻拦索技术，中国只能自行研制。所以，辽宁舰的改造经历了怎样的艰难历程，漫长的科技攻关之路遇到的重重障碍就可想而知了。疑难突破作为一篇新闻作品，本文是如何打动读者的？通过反复渲染、蓄势，营造训练现场的氛围，让读者透过文字感受从期待到紧张到彻底释放的心理过程，从而受到情感上的冲击。
第二十个全国中小学生“安全教育日”国旗下讲话稿
老师们、同学们，上午好！今天是第二十个全国中小学生“安全教育日”，所以，今天我讲话的题目是《珍爱生命，安全第一》，教育部长周济曾讲过这么一句话：“没有安全，何谈教育”，的确是这样，没有校园安全，哪来教育事业的发展。校园安全不但关系到每位同学能否健康成长，也关系到每个家庭的幸福。因此,我们必须清醒的认识到“安全无小事”。但校园安全事故每天都在上演，校园安全问题成了永恒的话题。楼道踩踏、食物中毒、溺水身亡、交通安全、违规用电、火灾火险、体育运动、网络交友、打架斗殴、流感病毒、毒品危害等等，这些校园安全事故时刻威胁着我们青少年学生的健康成长。下面我们听一听这些触目惊心的安全事故。XX年12月7日湖南省湘潭育才中学发生惨重的校园踩踏事件，一名学生在下楼梯的过程中跌倒，引起拥挤踩踏，造成8人死亡，26人受伤。XX年12月2日，山东东营某学校校车侧翻事故造成3名学生死亡。XX年12月8日，安徽省淮北市同仁中学篮球场边的高墙轰然坍塌，5名女同学的花季生命被永远定格在哪里。XX年4月27日，辽宁省葫芦岛市某中学6名学生校外私自游泳，溺水死亡。

XX-XX第二学期第六周国旗下讲话稿：珍惜粮食，做勤勉节俭的xx学子
尊敬的老师、领导，亲爱的同学们：大家早上好!今天我发言的题目是“珍惜粮食，做勤勉节俭的xx学子”。关于这个题目，我的发言有三点。第一，珍惜粮食，从我做起。“谁知盘中餐，粒粒皆辛苦”告诉了我们粮食来之不易的道理。学校领导很早就倡导全校师生开展“光盘行动”：盘里不剩菜，碗里不剩米。无论对于老师还是学生，这个标准都不能打任何折扣。可是现在，我们仍然可以看到有同学浪费食物的现象，吃不完的米饭随意倒掉，而且很“大方”、不犹豫。试想，我们学校近300名师生就餐，每人每顿少浪费一粒米，这数额积累下来，至少可以让一个饱受饥饿之苦的人解决温饱问题，这样下来，又可以节约资源求得学校更好的发展，何乐而不为呢？都说温饱不忘饥寒，增产不忘节约。我们处在衣食无忧的好时代，学校也处在稳步发展的关键时期，我们要从自身做起，珍惜粮食，杜绝浪费。

1.师要注意区别教学内容是否适合进行小组合作探究。这种学习是否每节课都需要。学生的小组学习是否在走过场，或者说流于形式。教师要注意营造自由自在的学习氛围，控制讨论的局面，如讨论中是否有人进行人身攻击，是否有人垄断发言权而有的人却一言不发，是否有人窃窃私语，教师要在巡视及参与中“察言观色”，及时调控。2.教师要充分注意精心设计的问题。教师的教学设计是否合适，是做秀还是教学的需要。这不仅需要教师的认同，还需要课程的认同，学生的认同。因此，对于适合采用小组合作探究方式的教学内容，我们一定要根据课程标准的三维目标学生现有的认知程度和兴趣以及本课要解决的问题和教学任务来精心设计问题。3.要注重小组合作探究的组织,进行适当有效的指导。教师要转换自己的角色，从传授者变成指导者、参与者、监控者和帮助者，并切实注意自身行为的方法和效果，及时进行调整。
