    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!

    高二学生国旗下讲话:在思想下学习

    尊敬的老师们、亲爱的同学们:大家早上好!前些天,诺贝尔奖得主陆陆续续揭晓,这些与我们朝夕相处的学科,在十月份聚焦了人们的目光,也让人看到了这些基础学科的力量。说这些,肯定会有人对此不屑,我们每天打交道的语文,不过是背一些东西,写一些废话,学几篇课文,我们每天打交道的理化生,不过就是做一些题,背一些结论,考几次试。这就是我们对真正的学习所持有的态度和方式吗?我们与这些基础学科相伴了多少年,认识仅停留于表象吗?这里可以与大家分享几个例子。1957年诺贝尔奖得主杨振宁曾说,他在西南联大时老师辛勤讲授的基础知识给了他扎实的功底,这些在后来依然有用。留学时导师要来时不时地提出一些新观点也给他留下了深刻的印象。
