1000科学小知识作文800字
全文共 846 字
+ 加入清单科学可以告诉我们很多知识,如果你想明白其中的奥妙还需自己动手做实验,也可以找“百度”来帮帮忙。
这个星期天,我早早地做完了回家作业,和爸爸一起看着有关特务类的电影。忽然出现的一个场景引起我的好奇心。电影里的一个特务手里拿着一根棉签,再用柠檬挤出一盘子的柠檬汁,再用棉签蘸着柠檬汁在纸上写着字。我猜想纸上的字一定是情报。可是,等到纸干了,字也随着消失了。接着就是收情报的演员,他接过情报用打火机在纸上慢慢的烧着,不一会儿,纸上的字就又显示出来了。我指着电视上的情景不解的问爸爸:“爸爸,这是怎么回事,字为什么会不见了呢?”
爸爸摇了摇头道:“这个我也不知道。”
“不过,你可以自己做一个跟他一模一样的实验,或许就知道了其中的奥秘。”
“嗯,那好吧。”我听了爸爸的话,开始准备着材料。
不一会儿,材料就准备好了有:一碗柠檬汁、一根棉签、一张干净的白纸和一个打火机。
我学着电视里的特务,用蘸过柠檬汁的棉签在纸上写满了密密麻麻的字,放在桌子上晾干,大约过了一两分钟,字就干了。我再拿出打火机在纸的底部用打火机烧,不一会儿纸上消失的字真的就又能看见了。我大声的叫道:“OMG,好神奇呀!”
可这是为什么呢?我百思不得其解,最后还是决定问一下“百度”。
百度上是这样告诉我的:纸内含有的淀粉,会与碘产生化学反应形成碘淀粉分子,而呈现深蓝紫色;而柠檬汁中含有丰富的维生素C,当维生素C与碘产生化学反应时,会产生无色的现象。因此以柠檬汁写字或画图的部分不会有颜色改变。
因为柠檬汁中含有一种叫赛璐酚的成分把它写在纸上,可以降低纸的燃点,只要用火一烤,柠檬汁写字的部分最先被烤焦,呈现黄色的字就能显现出来了。
这让我又想到了另外一个电影:一个小特务,每天都会在街上卖鸡蛋,而且买鸡蛋的人总是那几个,我发现原来鸡蛋里是有情报的,因为小特务用笔蘸着醋在鸡蛋壳上写字,可是当鸡蛋一煮熟,字就会在蛋白的表面,这样情报就不会被发现了。
通过这两件事例让我更加爱上了科学,更加喜欢科学,也让我明白了原来大自然和生活中就能发现很多的科学小知识。

篇1:小学森林防火知识
全文共 661 字
+ 加入清单俗话说“水火无情”,在所有的自然灾害中,发生频率最高的就是火灾。一个小小的火星就可以使大自然的宝贵资源遭到破坏,可以使人类创造的物质、精神财富化为灰烬,可以无情地夺走人最宝贵的生命。
为了让全校师生更深入地了解消防逃生常识,使每一位师生都树立起消防意识,真正的掌握好消防安全知识,并具备自救互救的能力。我们学校准备在“119消防宣传日”举行消防大演习。老师要求我们每个人都要带一条毛巾,到时需要用。
下午第二节课一上课,我们先听了消防知识讲座。消防叔叔给我们讲了一些平时火灾发生时应有的常识:如打119电话、大声呼救、等等,紧接着就是火灾逃生演习。校园里响起了电铃声,一听到铃声,老师一边指挥我们赶紧离开教室,一边教我们把毛巾捂住鼻子,并排好队有秩序的下楼。我边听边快速拿出毛巾轻轻地捂住鼻子,然后弯着腰紧跟着同学跑向操场。紧张的逃生刚结束,接着是灭火演习。校长洪亮地宣布:“灭火演习现在开始!”话音刚落,操场上响起了热烈的掌声。消防叔叔们把大火点燃了。火好大呀,在这燃眉之急消防叔叔个个不慌不忙拿起灭火器,先拔出钥匙,然后把灭火孔对准着火点,再按下开关,只见粉沫纷飞,我还来不及看清楚火竟然灭了,叔叔们的动作好快呀!后来五、六年级的学生代表和老师代表也去演试了试,演习在欢声笑语中结束了。在演习中,我学会了如何安全逃生,如何灭火,也深深的明白了,遇到任何事情都要镇静,不要慌张,真是受益匪浅。
学好消防知识让我们携起手来,为减少火灾的发生而共同努力,从我做起,从今天做起,真正做到防患于未然,让我们日益强盛的祖国更加祥和安宁!

上学期的作业非常少,我要等妈妈下班后一起回家。每当我写完作业后,我都会拿出书来,在一旁静静地看书。每周,我都要在科普图书馆借上三本书,而家里妈妈准备的名著,却不曾看。我喜欢借《笑猫日记》《马洛丽成长记》等故事书。我看书时,妈妈总会在一边唠叨:“老看这种小人书,有什么用?”我没有理妈妈,还是在一旁津津有味地看书。因为,我知道,无论看什么书,都会有用的。
我还爱看关于科学的书。
有时我看到星星在向我眨眼睛,就会问妈妈:“妈妈,为什么天上会有星星和月亮啊?”妈妈只会说:“你问我,我问谁?”妈妈不懂这样的科学道理,每当这个时候,只会说像这样的话。哎!我只有靠读书了。我还会借一些关于宇宙的故事的书,去认真的看,认真的读,这样就可以找到答案了。而妈妈还是说那老掉牙的话:“不读名著,读这个干嘛?”我感到很苦恼,我读什么书才行呢?
我读不懂那些名著,我根本不懂那时什么情况,怎么能读懂名著呢?我想告诉妈妈,读这些书也可以让我收获很多知识的!
篇4:初中英文
全文共 826 字
+ 加入清单Dear Michael,
You want to know the changes about my hometown. You know, great changes
have taken place since 60 years ago.
In the past, the living conditions were very poor. There were not many
buses or cars, and the roads were narrow. Usually, a big family was crowded into
a small, dark house. Most families couldn’t get enough food. The communications
were simple and slow. People kept in touch with their friends and relatives far
away mainly by letter or telegram.
Thanks to the government, our hometown has developed rapidly in recent
years. The living conditions are much better and more comfortable. The roads are
wide. Some people have their own cars. Most of the people live in big new
houses. Quite a few adults have mobile phones. I think our lives will become
better and better because of many good policies.
Sincerely
Kang Min

+ 加入清单今天的科学课是昨天布置好的让我们带一种水生植物——水葫芦,爸爸昨天晚上在环城河给我捞了几棵,可惜我早上还是忘记在妈妈的车里了,幸好有好多同学都多带了。
老师让我们4个人一小组分别观察水葫芦的结构,通过这堂科学课我懂了原来水生植物可以分三类:挺水植物、浮水植物、沉水植物。有些是全部浮在水面上,有些是根在土里,叶在上面上,像水葫芦是叶子在水面上,跟在水面下,没有泥土也可以生长。
我喜欢上科学课,让我懂得了更多大自然的知识。
篇6:收获了知识作文300字
全文共 404 字
+ 加入清单在生活中,我们可以发现许多神奇的景象,今天,我做了一个小实验,让我又学到了不少新知识。
星期天,我在家中闲着无事,便拿出几个鸡蛋来“研究”。有个鸡蛋一不小心掉进了桌子上的水盆里,一会儿就沉了下去,我突发奇想,如果在水里加入一些东西,鸡蛋是不是就浮起来了?说干就干,可在这时,我又愣住了,加什么东西会浮起来呢?这时,我的目光落在了盐上,死海的盐很多,人可以浮在海面上,那鸡蛋应该也可以浮起来。我往水里放了四五勺盐,然后将鸡蛋放进去,可还是没有浮上来,我一生气,将整袋盐都倒了进去,鸡蛋终于浮上来了,我惊喜万分。可却不知这是为什么,便去请教“无声的老师”。
原来,鸡蛋之所以在水中下沉,是因为鸡蛋的密度大于水的密度。而当往水里添加食盐后,食盐在水中溶解,水的密度渐渐增大,浮力也渐渐增大,当继续添加食盐,使水的密度足够大时,鸡蛋便浮起来了。
看吧,生活中的知识无处不在,只要细心观察、不断探索,就一定能发现更多的奥秘!

篇9:星星英文
全文共 928 字
+ 加入清单During the summer holidays, I went to my grandmothers home. One evening after supper, I stood on the balcony to look at the sky.
The stars in the sky were twinkling. Some were crowded, and others were separate. Then I found that the stars were not the same colour. They were white, grey, light blue and orange. It was really beautiful. At that time, the sky was like blue damask decorated by millions of bright dimonds.
Looking up at the sky, I saw the moon. It was like a naughty child, sometimes it hid in the clouds and sometimes it got out of the clouds. It seemed to play “hide and seek” with us. The stars around the moon, however, were as shy as girls, and hid themselves in the clouds.
Oh, what a beautiful sky!
在暑假期间,我去了我奶奶家。晚餐后的一个晚上,我站在阳台上看天空。
天上的星星闪烁着。有些人很拥挤,有些人则是分开的。然后我发现星星不一样的颜色。他们是白色,灰色,浅蓝色和橙色。真漂亮。那时候,天空是蓝色的缎子数以百万计的明亮的钻石装饰。
抬头望着天空,我看到了月亮。它就像一个顽皮的孩子,有时它藏在云层里,有时它就从云层里出来了。它似乎和我们玩“捉捉”。然而,月亮周围的星星,像女孩一样害羞,并躲在云层里。
哦,多么美丽的天空!

我长大以后我也要当科学家。
篇11:生活中的语文知识作文650字
全文共 624 字
+ 加入清单生活中的语文知识,无穷无尽,就像天空中闪闪烁烁的星星,琳琅满目,永远也望不到边。
在包罗万象的生活中,语文知识是随处可见的。一向爱发现的我,今天在大街上看到了这样有趣的广告语,服装广告:百衣(依)百顺;蚊香广告:默默无(蚊)闻;止咳药广告:咳(刻)不容缓;热水器广告:随心所(浴)欲;礼品店广告:礼(理)所当然;蛋糕店广告:步步糕(高)升;帽子广告:以帽(貌)取人;……像这样的广告语还有很多,当我看到这种现象,我觉得人类不应该刻意的错用这些字,这样会使更多的人误解,我建议尽可能写成正确的词语。
在动物园里,我也见过许多“保护动物”的公益广告;1、保护动物就是保护我们的同类。2、是先有鸟还是先有蛋,你不知道,我不知道,只有鸟知道;是鸟先消失还是蛋先消失,你知道我知道只有鸟不知道,3、动物是人类亲密的朋友,人类是动物信赖的伙伴。这同时用婉转的语言呼吁人们,保护动物!
在敬老院里,有“尊敬老人”的公益广告:1、善待老人就是善待明天的自己,2、老吾老以其人之老,幼吾幼以其人之幼,3、父母是孩子的老师,尊老爱幼是美德。
在电视上,我也看见过“社会公德”的公益广告:1、高空抛物,砸在地上一个坑砸在头上……2、不能在丢垃圾时丢了自己的脸。
在学校,我们会经常见到走廊上写着“请说普通话”的广告语:1、沟通你我他,全靠普通话,2,说普通话迎四方宾客,用文明语,送一片真情。
生活中的语文知识虽多,但还是重在发现,重在积累,重在观察。让我们共同走进生活中的语文吧!
篇12:关于知识产权作文
全文共 1025 字
+ 加入清单盗版的商品在我们的生活中越来越常见。盗版书籍、盗版CD等。前几天,面对便宜的盗版字典,我心动,于是便打消去书城的念头,掏钱将其买下。但很快发现我错,盗版别人的东西是一种犯罪,而我的这做法指只会助长这种行为。为此我感到非常后悔。我们青少年应该要维护他人的知识产权。
世界上的许多东西都是人类智慧的结晶。人类从来没有停止创新的脚步,正因为如此科技越来越发达,精彩的书籍也越来越多。我曾经做过一个梦,在梦里我去图书馆却找不到新的作品;与同学去电影院却看不到新的电影;去歌剧院却不能欣赏崭新的乐章;科技馆里也没有更先进更有趣的发明。这一切的罪魁祸首都是盗版,因为作家、音乐家都需要生活,由于这个原因创新精神在现代社会中逐渐流失。所以我们应该要维护上所有的知识产权。
维护知识产权,让创新精神继续发扬。
不断的创新,社会才会不断的发展。人类自古以来就梦想着能像鸟儿一样在空中飞翔,于是就出现风筝。在1903年,莱特兄弟创造第一架靠自身动力进行载人飞行的飞机“飞行者”号,而且试飞成功。但是拥有创新精神的人类并没有停下脚步。1910年,亨利发明的首架采用喷气发动机的飞机与人们正式见面。虽然在12月10日的试飞过程中,飞机发生意外,亨利献出自己宝贵的生命。但这也没有阻止人类去创新的脚步。最后科学家终于成功解决原来发动机存在的问题,制造出喷气飞机。1939年9月14日,第一架实用型直升机诞生,这架直升机可以说是现代直升机的鼻祖。在接下来的时间里又相继出现民航机、空中客机等。这一切的进步,拉进世界人们的距离,使得各地的交流日益频繁,社会发展也越来越好。
所以创新精神是人类社会不断进步所不可缺少的。船的发展也体现这种精神的重要性。船舶从史前刳木为舟起,经历独木舟和木板船时代,1879年世界上第一艘钢船问世后,又开始以钢船为主的时代。船舶的推进也由19世纪的依靠人力、畜力和风力(即撑篙、划桨、摇橹、拉纤和风帆)发展到使用机器驱动。原子能的发现和利用又为船舶动力开辟新的途径。有更先进的船,同时在指南针的指导下,人们在海上航行的范围更加广阔。因此世界在某个意义上是缩小,不同肤色、不同国家的人们联系更加紧密。
如果没有创新精神,就没有新的创造,更没有今天的21世纪。就是因为人们在不断的创新,人类的生活才会如此美好。都让我们的生活更舒适酷热的夏季,有空调帮我们调节温度;电视让我们不出家门可知天下事;计算机让我们解更多的信息等让我们的生活更舒适。
创新,将世界联系在一起。

随之,我们又去了一个全部都是大棚的地方,大棚里种了许多不同的蔬菜,隐隐勾起了我的食欲。下一站,我们又去了一大片树林,里面的树也有多种,形态也各不相同,有高的,有矮的,有粗的有细的。树上那一片片嫩绿的小叶子水灵灵的,多惹人喜爱呀!

回到了学校后,那些发生的事我仍历历在目,而这一次研学旅行,我学到了很多,在实践中学习,是一种多么好的办法呀。
篇16:安全消防知识作文
全文共 647 字
+ 加入清单自从盘古开天,火是人类最伟大的发明。咱们的生活离不开火,但是如果用火不当,火就像一个恶魔,吞噬人类的生命和财产。所以说它就像一把“双刃剑”。咱们在日常生活中应该小心谨慎地用火。只有这样,咱们才能建造美好的家园。下面我来讲一个亲身经历的教训。
还是我五岁那年。我一个人在房间里玩,无意之间看到了一个打火机,我学着爸爸的样子使劲按了几下,“咔嚓”一声,没想到竟然被我给点着了,差点烧到我的手,我非常害怕。便把燃烧着的打火机扔进了垃圾桶,没想到垃圾桶也烧起来了。我迅速把爸爸妈妈扯进房间。爸爸妈妈一进门便吓得目瞪口呆,立即拿来了一盆清水,把燃烧的垃圾桶扑灭了。这下我才松了口气,后来爸爸妈妈严肃地批评了我,告诉我:如果不及时扑灭的话,后果将不堪设想。因为,火不断地蔓延,会把整栋楼化为灰烬。并告诫我以后再也不能犯同样的错误了。从那一刻起我就明白了:不是任何东西都可以拿来玩,特别是火这一类危险物品,千万不能随便玩弄。否则,失去的将是宝贵的生命。
随着年龄的慢慢增长,我了解了更多的消防知识,也更加明白了“水火无情”的道理。一但遇到着火,千万不要慌张,一定要保持冷静镇定,最好早报警,牢记火警电话“119”,报警时讲清楚地址。起火原因等;决不能贪恋财物。首先要逃跑或找大人;逃跑时应用湿毛巾捂住鼻子,以免中毒;同样也要严守秩序,不能争先恐后,互相拥挤,自相踩踏,以免发生不该发生的悲剧。
每个人只有一次生命,咱们要珍惜自己和他人宝贵的生命。同学们,让咱们多了解消防常识,从小树立消防意识,争做消防安全小卫士。

+ 加入清单星期一,爸爸妈妈一大早就上班去了,我呢,不言自明,当然是自己呆在家里了,寒假作业已经全部写完,我百无聊赖地坐在书桌前,不知干什么好。突然我的大脑指挥官下达了看书的指令,于是,我便走到我又高又大、陈列着几百本书架前,选出了一本我百看不厌的《少儿百科全书》来看,因为,在这本书里面,可以了解很多我不知道的知识。下面,让我来给你介绍一下,我在这本书中汲取到的各种好玩、有趣的知识吧!
例如:憨态可掬的大熊猫是我国一级保护动物,非常稀少,现在只有1600多只,是我国的国宝;海龟被称为长寿之神。你可别小瞧松鼠的尾巴,它的尾巴有很多作用,打扫卫生时可以当做扫帚,从高处往下跳跃时可以当做降落伞,冬天冷的时候还可以当做棉袄;矿泉水瓶盖拧不开的情况下,可以通过热胀冷缩的原理把矿泉水放在热水里面泡一会儿就可以了;鲸鱼“集体消失”的原因是深海环境污染过大,鲸鱼们都集体往浅海区游,因为身体过重的缘故,呼吸困难,所以内脏被压坏,才导致集体身亡;小鸡吃石子是因为小鸡的胃壁非常厚,像一个橡皮袋,小鸡吃石子有助于它们的胃消化;皮球掉进洞里了,不要着急,可以往洞里面多倒一些水,这样,皮球就能浮上来了……
《少儿百科全书》与我相伴,丰富了我的知识,开拓了我的眼界,使我的生活变得丰富多彩。我喜欢《少儿百科全书》,但我更喜欢那种收获知识的快乐。小朋友你收获了什么呢?

全文共 15233 字
+ 加入清单01, happiness is to work late at night, and back to their downstairs, looked up to see the window of the living room still showed little light.
02, happiness is the dead alone and read a book under the lamp, happened to read a word touched the heart the most delicate nerves, inadvertently looked up and found that the orange light softly covered room.
03, happiness is like people, in a favorite place to do what you love, whether it is love or quarrel.
04, happiness is the road to see a blind musician is playing the flute, melodious flute hauntingly, who took out all the change, turn left at the time, the pace has become light up.
05, we sometimes mistakenly believe that what we cannot get is precious; what we already own is cheap. Unable to obtain, because of the lack of in-depth understanding, it is just a beautiful illusion, showing us a gorgeous appearance. If one day, you close to it, and know the truth, you will find that it is similar to what we have! Dont keep your eyes in your imagination. All you have is your happiness.
06, you should dare to put the future of happiness on my body, gambling, I dare to live with you, to the last let you lose.
07. The wind is transparent, the rain is ticking, the clouds are flowing, the song is free, the bells are wonderful, you are the happiest.
08, happiness is a feeling, like a candle, when you walk in there is a piece of lamps and candles of a myriad families, the warm fluorescent light your way home; like a aftertaste lingers in the heart, all sorts of joys and sorrows are once the chase; like a desire, longing when time crawling forehead wrinkles, can still calm happy and deserved no regrets. Happiness is a glass of imagination, dreams of ordinary rice brew wine fragrance, and then waiting for life and treasure.
09, in the right place, met the right person, that is real happiness. Therefore, in every windy day, we will be full of thanksgiving heart, thank you for the fate of our meeting, thank you for life, let us walk in the helpless intersection of the encounter.

篇20:科普知识作文
全文共 473 字
+ 加入清单观看了《神州十号太空授课》后,我就心理暗暗发誓:长大后一定要做一名航天员!驾驶着航天飞机飞向太空。因为只有在太空才能在做一些平时我们生活中做不到的动作,譬如:航天员可以在船舱里飘来飘去,如果我们想在房间里飘起来,是不可能的;在航天飞机上可以看到我们美丽地球的全貌;一望无际的宇宙和数不清的行星、彗星、还有会飞得流星.......
同时,我也很佩服我们的航天员,他们能利用牛顿第二定律给在失重环境下给航天员量体重,再进过负责的组装,做出了太空体重器。
在佩服我们敬爱的航天员的同时,我还学到了很多知识:知道了在太空失重环境下的水,也会浮动起来。航天员给我们展示了把金属圈放在水里拿出来,圈里的水像被黏住了,把金属圈轻轻摆动,圈里的水居然都没有掉落下来。我还知道了“单摆”在太空是不会左右摆动的,而且只要用一点点力来推这个用来做实验的“小球”,“小球”就会做旋转运动。
在视频里航天员问我们:“可以用其他什么方法可以测质量?”我想:只要先知道航天员在地球上,相等条件下的转动频率,然后再测得在太空中的转动频率,相对比,就可以知道航天员比以前胖了,还是瘦了。
