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!

人教版新课标高中物理必修1力学单位制教案2篇
一、教材分析在初中阶段，物理量单位的学习是学生较为困惑的问题之一。前面关于1N的规定给学生的印象总好像是有些随意。尤其是牛顿、帕斯卡、安培、伏特、焦耳、瓦特等单位的规定。使得学生感动物理太复杂。事实上，只有把单位制放在整个物理学框架中加以认识，并且知识有了一定的积累。经历了充分的学习过程后才能体会物理量单位的命名和使用规则。体会到其中对一些单位进行规定的合理性和方便特征。物理学单位中，有很少几个基本物理量，它们的单位就是基本单位。在进行了这种选定之后，其它物理量的单位就是根据它的定义式，有所选择的其他物理量的单位共同确定的。国际单位制的建立和使用，不仅方便了国际间的交流，也逐渐成为科学研究中计算和运用的一种规范约束。中学生应该注意学习，逐步习惯，在记录、表达和计算中规范使用。二、教学目标（一）知识与技能1．了解什么是单位制，知道力学中的三个基本单位；2．认识单位制在物理计算中的作用

安徽省2018年中考历史真题试题（含解析）
根据题干信息“汉代陵阳县，晋为避杜皇后名讳改名广阳，后又避隋炀帝名讳改名南阳”，由此判断这是中国古代社会的特有的“避讳”现象；结合所学知识可知，中国古代，“避讳”的意思是在帝制时代对于君主和尊长的名字，必须避免直接说出或写出。所以“陵阳”避杜皇后名（杜陵阳）讳改名广阳，后又避隋炀帝名（杨广）讳改名南阳，这种“避讳”，体现皇权至高无上，选项C符合题意；而选项ABD与“避讳”无关。因此只有选项C符合题意，故选C。
