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:?

初中语文《阿西莫夫短文两篇- 被压扁的沙子》试讲稿_教案设计
质疑问难，合作探究 1、文章是介绍沙子的知识吗? 明确： 有关恐龙灭绝的原因，原来本文的主角不是沙子，而是恐龙。 2、题目是《被压扁的沙子》，内容却恐龙灭绝的原因，题目《被压扁的沙子》是否偏离主题了?我们换成《恐龙是怎样灭绝的》会不会更好? 本文题目不但没有离题，还能提示读者，恐龙灭绝的“撞击说”所以产生，与被压扁的沙子的科学发现和科学研究密不可分此外，文题形象性强，容易激起好奇心，引起人们的阅读兴趣 3、恐龙灭绝的原因一直是学术界有争议的问题，因而产生两种学说“撞击说”“火山说”在探究恐龙灭绝的原因时，作者的观点是什么?他的观点以什么为依据，又是怎样推论出来的?

人教版高中生物必修1生命活动的主要承担者—蛋白质说课稿
第五，蛋白质的功能。蛋白质功能具有多样性，由学生对照教材，进行总结。为什么蛋白质有那么多功能呢？根据我们学习生物学的经验可知道：生物的结构决定功能。再要求刚才的那四个同学上台组合多肽链。以不同位置组合，就会形成很多种多肽链，进而形成很多种蛋白质。每一种蛋白质都有其特定的功能，所以蛋白质具有多样性，其功能也具有多样性。第六，总结。蛋白质是细胞和生物体中重要的有机化合物，是一切生命活动的主要承担者。蛋白质的多样性是形形色色生物和绚丽多彩生命活动的物质基础。（可以由学生总结）第七，教学评价。由于只有一节课时间，课堂上对重点、难点知识的解析还不能做到举一反三的深度，因此尽管学生课堂反应热烈，对知识点的接受程度也达到了预期的要求，但在做课后练习时，也会出现一些问题。所以传统的讲练结合还是要结合起来运用才能取得更好的效果。为此本节内容需要2课时来完成。

感恩环境?学会爱护--从身边的小事做起
尊敬的各位评委、辅导员老师们：大家上午好！我是乌苏市第三小学的参赛选手xxx，今天我的少先队活动是围绕《少先队活动课程指导纲要》六年级的“德语养成目标”制定的，下面我将从活动背景、活动目标、活动准备、活动过程、活动反思等几个方面作具体的阐述。一、活动背景今天我带来的是少先队活动主要围绕“感恩环境”这一主题开展的。环境问题是关乎到国计民生的问题，是建设和谐社会的重要任务之一，也与我们的生活息息相关。结合我校的八大德育课程体系，我将这次中队活动主题定为《感恩环境，学会爱护》从身边的小事做起，希望通过这次活动，让孩子们能够学会感恩环境，学会爱护环境从自己做起。二、活动目的1、提高学生环保意识，改变不良生活习惯，通过观看环保视频，环保知识问答，发表感想的方式培养学生环保观念。2、让学生通过感受自然，学会体会人与自然的和谐相处，并明确我们生活中的一切都是大自然带给我们的，以此让学生学会感恩自然、感恩社会。3、让学生知道一个公民的义务和责任，是学生能够正视感恩的魅力，明白感恩是一种爱的表达，做人的责任。
感恩环境，学会爱护-从身边的小事做起说课稿
辅导员小结：通过看视频、环保知识问答、谈感受、动手做等系列活动，我们了解了许多环保知识，同时也明白了保护环境的重要性。并再次提醒我们保护环境，可以从身边的小事做起，是我们每个人都可以做到的，也不要让这句话成为空话。五、活动反思：上完本次队会课，我感触较深。首先，通过这次主题队会，我学会了彻底放手让队员去主持队会，要相信自己队员，敢于放手锻炼队干部。其次，要注意细节教育，中队会结束后，大队辅导员就指出了个别队员的红领巾佩戴不够端正，队礼不够标准。想想平时我也注意到了，但只是偶尔提醒一下，没有引起重视，这在我以后的队会活动中一定会加强的。最令我欣慰的是，这次主题队会让队员们都感受到了环境对我们的重要性，感受到环境受到污染，对我们的生活所造成的影响。尽管本次队会已经结束了，但是相信孩子们都会怀着一颗感恩的心将感恩的火种传递下去，从自己做起，从小事做起，保护我们赖以生存的自然环境。
人教版高中政治必修1按劳分配为主体-多种分配方式并存说课稿
4、课堂讨论：社会主义的根本原则是共同富裕，这也是正确处理分配关系的目标。而十五大报告却进一步明确指出“允许和鼓励一部分人通过诚实劳动和合法经营先富起来，允许和鼓励资本、技术等生产要素参与收益分配”。这矛盾吗？为什么？以小组方式进行讨论，再以代表的形式发表意见，这样既调动了学生的积极性，也使学生对内容有了更深层次的了解。最后老师加以总结，用“蛋糕效应”来阐述“效率优先，兼顾公平”的关系，既形象又贴切，加深学生的理解。本课时内容比较抽象，学生对于概念的理解有较大的难度。因此在教学中我采用多媒体课件教学，联系生活实际，让学生在生活中去体会货币的职责，区分货币的职能，以便达到学以致用的目的。同时适时设置疑问，让学生与我共同思考，真正实现“师生互动，生生互动”，调动学生积极，主动的参与到教学实践活动中。（三）课堂小结，强化认识。（2—3分钟）通过归纳小结，既强调了重点，又巩固了本节知识，帮助学生形成知识网络，便于课后理解记忆。
