科学演讲稿
科学演讲稿我演讲的题目是《科学就在身边》。
您知道向日葵为什么总是向着太阳吗
您知道冰淇淋为什么会“冒气”吗
您知道为什么燃烧的火焰总是向上窜吗
这些发生在我们身边的司空见惯的平常现象，里面却蕴藏着深奥的科学知识。
凡是有成就的科学家，他们都善于抓住身边的看似平凡却蕴含科学道理的一些小事，进行深入细致的研究，最终攀登到了科学的高峰。
英国科学家牛顿被掉下来的苹果砸中了头而研究出了万有引力定律；英国瓦特观察水烧开后的壶盖发明了蒸汽机，我国古代发明家鲁班的手被带齿的草叶划破发明了锯子……他们都是捕捉了身边的现象进行科学的研究后取得的创造成果，这些发明推动着人类文明的历史前进。
事实上科学家的很多发明都是从我们身边的科学中得到启示的：船和潜艇来自人们对鱼类和海豚的模仿；火箭升空利用的是水母、墨鱼反冲原理；直升机是人们通过对蜻蜓飞行的研究发明的……尊敬的各位领导、老师、同学们，这样的例子还要我再列举吗
不，不用了
我们遨游太空，这里有科学；我们品尝美味佳肴，这里有科学；我们欣赏五颜六色的鲜花，这里有科学；我们翻看各种书本，这里也有科学……，科学无处不在。
一个星期天，我突然发现邻居家的大白猫正在菜园里吃草。
觉得很奇怪，猫不是肉食动物吗，怎么会吃草
便回到家中找出《百科全书》查找，却没找到关于猫吃草的原因。
从此以后，我只要有时间，就仔细观察大白猫……皇天不负有心人，终于，我发现大白猫每次吃草，都会拉出稀薄的屎。
我猜想：也许大白猫吃草是因为它肚子不好的缘故
后来，这个猜想在一个宠物医生那里得到了证实。
我高兴得一蹦三尺高，我终于通过自己的努力获得了知识
从这件事中我明白了，只要我们认真观察，勤动脑，勤动手，时刻留意身边的各种现象，就能发现科学就在我们的身边
谢谢大家
我要一篇以“Culture Smart or Science Intelligent
”为题目的英语演讲稿。
好像是一个大学生英语比赛题目??
谁有金璐的演讲稿culture smart or science intelligent
What would you do if you had only one day left to live?“What would you do if you had only one day left to live?” I asked this question to my young students when teaching English this winter. What were their answers? “I would watch television!” the first answer. “I would play with the computer!” the second one. “I would play with computer TOO.” The girl finished her sentence perfectly with a serious smile. Indeed how cute and innocent that smile was, but how seriously my heart was hurt. I was too frightened to listen to more answers like that. Ten years ago, at their age, I had a different answer: I would spend the last day of my life gazing at the face of my dear grandmother until I inscribed every detail of it onto my mind. When grandmother was getting old and weak, my family bought her a telephone so I could save time and the trouble of traveling to her home by making phone calls instead. Later we bought her a television so she could watch modern dramas by herself. Then grandma must have been, we assumed, very contented and happy. But I never really knew how grandma felt. She silently passed away without a word one night. When I heard about her death, a chilling pain pierced my empty heart. The pain grew even sharper as I tried to remember in detail exactly how grandma looked and I failed completely! How could I remember? I had not visited her for ages—it seemed like a century! My memories of her dissolved into thin air and leaked away like water. Even though I have a telephone, can she hear me now?Even though I might be on television, can she see me now?Even though I have modern telecommunications, can she still communicate with me now?With all these “tele”s, I was powerless. Don’t people just love the word of “tele”, which means far away. Indeed this is how modern technology has changed our world. But please don’t forget this other word with “tele”: telepathy: which refers to human beings’ inborn ability to connect to our loved ones. Our minds are supposed to read each other’s minds; our hearts are supposed to feel each other’s hearts — and fulfill these without any forms of tool! But the moment I desperately struggled to remember grandmother’s face, the telepathy between her and me had shut down forever. With the help of modern technology, I killed our telepathy. This shall never happen again! The “tele”s are great inventions. But “telepathy” gives them the warmth of a human face. Let’s harness the power of television to excite our kids to develop their telepathy with nature… so that they can read the secret language of flowers. Let’s make the telephone lines provoke us to preserve our telepathy with each other, so we can connect in a warm and feeling way. Let technology keep our “telepathy” ALIVE! We need to wake up and make this happen. I told my grandma’s story to those young kids that day. They got very quiet. They asked me for a second chance to answer the question. They had come to a new understanding – that very moment they had made to me and to our future together, a dear promise.Thank you very much!

i have a dream 演讲稿80~100字左右
还记得一句歌词吗
”我知道，我一直有双隐形的翅膀，带我飞，飞过希望，我终于看到所有梦想都开花。
”看到它，你是不是觉得有点熟悉呢
对，这就是张韶涵的《隐形的翅膀》。
每个人都有双隐形的翅膀，带你飞到想去的地方。
你想去何方呢
现在就展开翅膀飞向它吧
说实话，我到现在也没确定自己想飞去何方，因为我的梦想总是在随着年龄的增长而不断的变化，或许，我想做个是十全十美的人吧
曾经，我想当发明家，用奇思妙想改变世界’想当科学家，学好本领，走进科学，看看在神秘的UFO里是不是真的有外星人的存在……我要探索无数未知的秘密，服务社会；想当妙手回春的医生，奇迹般的解除病人的痛苦；拥有艺术，用美丽的创造诗化自己的人生。
现在，我有两个梦想，第一个是想当一名才高八斗的服装设计师，在大街上，走到哪里都能看到人们穿着我设计的衣服愉悦地走着；在衣店里，随处都能看到我设计的衣服挂满了墙壁，而且人们都争先恐后地去买；回到家，打开电视，名模们穿着我新设计的衣服充满自信的做秀；歌星们穿着我设计的服装在舞台上尽情的释放自己的光彩。
那一刻，你就会觉得多么的欣慰与自豪啊
我的第二个梦想是当一名万众瞩目的明星，拥有无数人的爱戴，站在金光闪闪，璀璨耀眼的舞台上，在众目睽睽之下，用甜美，悦耳的歌声征服观众。
那时，我要用歌声使那些正在生命尽头与咄咄逼人的病魔作斗争的病人感到温暖，用最自信的微笑告诉病魔，你不会就此被他吓倒，你一定会好好活着的；我要用歌声使那些饱受战争洗礼的伊拉克和巴基斯坦的人民感到温暖，用最灿烂的微笑去迎接生活。
所以，从现在开始我一定要努力掌握各门知识。
让小小的梦想在我们心中萌发生长，让我们展开梦想的翅膀，飞到远方吧
我相信即便是最平凡，最不起眼的梦想，只要我们用一生的努力去追寻它，它就一定会在我们心中开出一朵美丽的花。
只有这样，你才能体会生活的意义，过的满足而安详。
Remember the lyrics? I know, I have a pair of invisible wings, take me fly, fly over the hope, I finally see all the dream blossom. See it, you is it right? Feel familiar with? For, this is Angela Chang's invisible wings. Everyone has a pair of invisible wings, take you fly to where you want to go. Wherever you want to go? Now expand the wings to fly it!To tell you the truth, I haven't decide oneself want to fly to where, because my dream is always in the growth as the age and constant change, perhaps, I want to be a perfect man!Once, I want to be an inventor, with the idea to change the world 'want to be scientists, learn skills, science, have a look in the mysterious UFO is it right? There are aliens...... I want to explore the many unknown secret, serve the society to bring a patient back to life; when the doctor, a miracle to relieve the suffering of the patient; with the arts, creating his own poetic life with beautiful.Now, I have two dreams, the first one is a man of great talent talents to be a fashion designer, in the street, you can see people wearing my clothes happily walked to where to go; in the clothing store, everywhere I design clothes covered the walls, and they fall over each other to buy; back home, turn on the TV, supermodel dressed in my new clothes full of confidence of the show; the stars in my design costumes on stage, enjoy the release of their luster. At that moment, how you will feel pleased and proud!My second dream is to be a high-profile star, love has countless people, standing in the glittering, bright and dazzling stage, under the watchful eyes of the people, with a sweet, sweet voice to conquer the audience. At that time, I want to sing that is the end of life and overbearing the fight against the disease the patient feel warm, with the most confident smile told her, you will not be intimidated by him, and you will live; I will sing to those suffering from the war in Iraq and Pakistan people feel warm, go to meet the life with the most brilliant smile. So, I must strive to master all knowledge from now.Let little dream germination and growth in our hearts, let us dream of wings, fly far away! I believe that even the most ordinary, the most ordinary dreams, as long as we use life to pursue it, it will open a beautiful flower in our hearts. Only in this way, you can understand the meaning of life, the meet and serene.
急，演讲稿
尽力创作，不满意的再修改处处皆科学我们生活的世界既神秘又有趣，需要我们探索它的奥秘，揭开它的本来面目。
从生活走向科学，让科学回归生活。
而科学 知识是科学素养的重要组成部分，科学探究是我们获取知识更为科学的途径，能够使我们获得对科学、对科学概念和事物更为深刻的理解。
科技是第一生产力，生活 中的科学无处不在，科学时刻影响着和改变着我们的生活；步入二十一世纪后，我们人类只有掌握好科技、运用好科技，才能进入全新的发展时代。
科技早已深深地 渗入到我们的生活，融为一体；科技正在不断加速行进，不知会把我们带向何方。
微软有句名言：微软唯一不变的就是变
这个世界也是这样。
科学关系到社会的发展，关系到人们如何认识自己在世界当中的位置，那么科学就不应该仅仅属于科学家，它也应该属于大众。
科技和教育，是大家既熟悉而又陌生的内容。
说熟悉，是因为它与大家密切相关，生活中随处可见“科学健身”、“科学养生”等说法，在这个意义上，“科学”与“有效”、“合理”等同。
它实际上体现出公众意识中的对于科普的实用性和工具性。
科学道理在生活中无处不在
举个生活中最简单的例子，同学们都有过被蚊子叮咬的经历，蚊子为什么会叮我们呢
根据对蚊子触须上神经细胞的信号记录结果，并配合触须细胞在电子显微镜的图片资料合并研判，蚊子触须细胞中有90％的设计，都是为了侦测空飘的化学物资。
因此，人所排出的二氧化碳、体热和乳酸，对于蚊子来说都有非常强的吸引力。
当然，这很合理，因为我们有热度、会呼出二氧化碳且汗液里也含有一些乳酸。
但更有意思的是，蚊子用什么聪明的仪器来侦测这三种引发它兴趣的东西，确保它有效率且安全的侦测出猎物所在呢
这就需要我们继续研究发现了。
还有用勺子吃饭时就用到物理中力学原理，樟脑球时间长了会消失就是用到了挥发原理，背东西还涵盖着压力压强的关系......只要认真观察科学道理无处不在。
说它陌生，是因为科教兴国，作为我国的一项基本国策。
我国的“神舟 七号”载人航天飞船的成功发射和返回就是个很好的例子。
自1992年 我国启动载人航天工程以来，神舟飞船已经是第七次出征。
继神舟五号、神舟六号之后，中国载人航天事业又向前迈出了坚实一步。
航天员翟志刚出舱进行太空行 走，并完成预定的空间科学实验操作，茫茫太空第一次展现了中国人的矫健身姿。
从无人到三人，从舱内到舱外，这是中国航天事业的新高度，也是中华民族科学技 术水平的新高度。
恰如胡锦涛主席所说：“实施神舟七号载人航天飞行任务，是今年我国最具代表性、最具影响力的国家级重大科研实践活动，是中国人民攀登世界 科技高峰的又一伟大壮举。
”的确，在21世纪，科学技术是时代信息中的一个关键词。
可以说，今天我们的一切，都已经离不开科学技术的发展。
从衣到食，从住 到行，从个人到国家，科学技术的发展，使许多童话中的故事变成了现实，人类上天入地不再是美好理想，呼风唤雨不再是痴心妄想。
在联合国和美国第37届国际《创造性解决问题讨论会》上，与会者达成一个共识，即，发达国家和落后国家的差距，实质上是创造力开发的差距。
落后 国家要想在经济、科技等领域缩小与发达国家的差距。
就要从开发人的创造潜能着手，有目的、有计划地逐步缩小开发人的创造力的差距。
这是一个有远见而深刻的 认识。
无怪乎，诺贝尔奖获得者李政道博士在访问中国科技大学时说：“培养人才最重要的是培养创造力。
”如今，“为培养创造力而教”已成为许多发达国家学校 教育的倾向。
现在,我国素质教育理论认为，学生是学习活动的主体，一切教育活动都要以学生为本，以学生的发展为本，即关键是培养学生的实践能力和创新精 神。
而且，古往今来，凡在科学上有突出贡献的人才，无一不是经历了从小接触科学，学习科学，进而产生兴趣对科学进行钻研，以致突破科学中的一些新领域，登 上科学的高峰的。
韩 国《东亚日报》称：“成为科学家，中学最关键”。
这就是说，中学时代是培养科学兴趣和创新能力的黄金时期。
而科学发明创造在我们身边无所不有，无处不在。
各学科的知识和实践无不潜藏科学的因素，只要我们认真观察，细心分析，大胆假设，小心求证，发挥想象，敢于创新，那么，我们每一位青少年都有可能成为发明 家和科学家。
科学在心中，创新在手中。
同学们，我们每一个人都是一个独立的个体，我们的思想和智慧都是独一无二的。
如果你没有创造的物质条件，那么就把你的 想法写下来；如果你有了一个新颖的想法，那么就让我们动手把它创造出来。
同学们，让我们以此次演讲比赛为契机，希望大家在平时的生活中，也时刻保持科技意 识，积极投入到日常的科技活动中，爱科学，学科学，用科学，寻找身边的科学，学会 用科学的方法解决一、两个生活中的问题，不断学习科学知识，培养科学精神，树立科学理想，掌握科学方法，提高自己的科学素养，让我们的生活处处皆科学
