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!

人教版新课标小学数学四年级上册速度、时间和路程的关系说课稿2篇
二、教材分析本节课是让学生结合具体情境，理解路程、时间与速度之间的关系。为此，教材安排了一个情境：比一比两辆车谁跑得快一些？从而让学生归纳出路程、时间与速度三个数量，进而归纳出速度＝路程÷时间，再结合试一试两题，让学生得出：路程＝速度×时间，时间＝路程÷速度，进一步理解路程、速度、时间三者之间的关系。因此，理解路程、时间与速度之间的关系是本节课的重点，难点是速度的单位。学习了这节课，学生可以解决生活中的一些实际问题，并且可以合理地安排时间，提高效率。三、学情分析学生对于路程、时间与速度的关系一定有所了解，但他们虽然知道三者之间的数量关系式，却并不十分了解为什么有这样的关系。因此，在课上应遵循“问题情境---建立模式---解释应用”的基本叙述模式，为学生自主参与、探究和交流提供时间和空间。四、教学目标
人教版新课标小学数学四年级下册把高级单位改写成低级单位：名数的改写说课稿
一、教材分析：《名数的改写》是四年级下册小数的意义和性质的内容。该内容是在学生已经学习了利用小数点位置移动引起小数的大小变化规律的基础上进行教学的。本信息窗呈现的是一只天鹅从出生到长大体重变化的情况。图中用文字标出了具体的变化数据。主要通过引导学生解答天鹅体重变化的问题，让学生体会到单位不相同，必须改写成相同的单位，展开对名数改写知识的学习。二、教学目标根据上述对教材的分析，考虑到学生已有的认知结构和心理特征，我确立了本课的教学目标为：知识与技能方面：会利用移动小数点的位置来进行名数改写。理解知识间联系，提高学生运用所学知识解决问题的能力。过程与方法方面：利用小数点位置移动引起小数大小变化的规律和名数改写的基本方法，引导学生进行知识迁移，从而掌握利用小数点的位置移动进行名数改写的方法。
人教版新课标小学数学四年级上册因数中间或末尾有0的乘法说课稿2篇
然后我让自主尝试探索末尾有0有乘法，然后让学生自己上台来给大家展示各自的算法，并讨论比较那种算法更简便，从而总结出末尾有0的乘法列竖式的简便方法。为了解决这节课的重点和难点，我在这个环节里又有针对性的设计了两个练习，一个是0和非0的对位，还有一个是积末尾补0。在教学因数中间有0的乘法，因为学生有了前面的基础，所以我直接让学生在两个问题中选择一个解决。重点强调了因数中间0不能漏乘。在练习方面，我设计了看谁的眼睛亮，通过找错误，学生练习时，老师观察到有共性的的错误，通过视频展示台，让学生来寻找错误，再次突破本课的重点。一题是360×25因数末数一共有一个0，而积的末尾应该有三个0。让学生进行讨论，再一次让学生体会了积末尾0个数确定的方法。在巩固和拓展联系环节，设计了闯关游戏，先是基本的计算练习，接着是因数末尾0个数的判断和解决问题的联系，通过练习，巩固竖式的简便写法，提高学生的计算能力。
人教版新课标小学数学三年级下册商中间或末尾有0的除法说课稿2篇
教法、学法分析我通过阅读教材、教参和新课标，分析学生学习状况，认为对这一教学内容理解起来比较容易。所以，在教学时我准备采取以下策略：1、放手让学生自主解决问题，尝试计算例7的1、2题。再通过学生口述计算过程，教师设问、强调重点使学生掌握本节课知识。2、通过学生反复叙述算理，培养学生口头表达能力，并使他们自主探索“被除数中间或末尾没有0，商中间或末尾有0”这一知识形成的过程。教学目标1、在熟练掌握一位数笔算除法法则的基础上，会正确计算商中间或末尾有0的除法的另一种情况。2、能熟练地进行商中间有零和末尾有零的除法，形成一定的笔算技能。3、能结合具体情境估算三位数除以一位数的商，增强估算的意识和能力。
