❶ 一篇简单的科学实验英语作文，实验越简单越好，如梳子梳头产生静电
The development of science and technology makes our life more comfortable and convenient. However, scientists have created many problems, which are not easy to be resolved, such as air pollution, the deterioration of environment and the scarcity of natural resources, to which we must some solutions.
Modern science and technology render people many advantages. Modern telecommunication shortens the distance between people and makes communication much easier. Internet is widely used now not only for collection of abundant information but also for correspondence. Email, the most effective communication device now, is becoming very popular. Besides, telephone and mobile phone make contact more convenient than before.
Modern transportation, such as airplanes and high-speed trains make our journey smooth and fast. With the help of modern transportation, people can go everywhere they prefer to. The journey to outer space and other planets is not a dream any more. Rockets and space shuttles can help us realize the dream of space travel.
Modern medicine prolongs peoples life and relieves patients of sufferings from many diseases. Cancer and AIDS are fatal to peoples health. Thanks to the endeavors scientists have made, these diseases become treatable.
However, the process of scientific development also arouses many sever problems to our human beings. Internet, though widely used in modern communication, is easy to be destroyed by computer virus. Outer space exploration has proced much waste in the space. A tiny metal, a screw, for example can destroy a flying man-made satellite. Instrialization is making natural resources become scarce.
Confronted with these problems, scientists are seeking prompt and feasible solutions. The development of science and technology bring about both positive and negative effects to us. We must eliminate the positive effects to the least extent.

❸ 关于如何上好科学实验室的英语作文
这个时候，最重要的就是认真听讲，把每堂课的知识点都弄明白。功在课堂，利在课后，如果专在课属堂上能基本掌握所学的基础知识和技能，课后复习和做作业都不会发生困难;如果上课时不注意听讲，当堂没听懂，在课堂上几分钟就能解决的问题，课后可能要花费几倍的时间才能补上。因此，同学们在课堂上集中精力听好每一堂课，是学好化学的关键。听课时，一定要聚精会神，集中注意力，不但要认真听老师的讲解，还要特别注意老师讲课的思路和反复强调的重点及难点。边听课边记笔记，遇到没有听明白或没记下来的地方要做些记号，课后及时请教老师或同学。

❹ 英语作文《科学实验的步骤》
上次科学课，我带着洋葱、小刀走近科学教室时，一眼就看到教室后面放着十几个显微镜。心里不由得嘀咕：教室里有显微镜，还让我们带洋葱、小刀，莫非、、、、、、
果不其然，这节课要大家观察洋葱表面的细胞结构。老师先让我们做标本，我和同桌顾丽娜照老师说的做了起来：我小心翼翼地用小刀把洋葱表面的一小层薄皮撕下来，紧接着，顾丽娜在载玻片上滴了一滴水，我小心地把洋葱皮平放在滴了水的载玻片上。最后，老师给了我们一片盖玻片，让我们盖上去。这块盖玻片看起来很脆弱，仿佛稍一用力就会碎掉。我们像对待太后一样，小心翼翼，轻手轻脚地，不敢有一丝怠慢。终于，盖玻片平安无事地在洋葱表皮上“安家落户”了，我们也松了一口气。
接下来，就是十分重要的一步——调节显微镜。我轻轻地取下盖子，放在桌子上。接着，就是调节反光镜。我们一点一点小心的移动反光镜，直到看到一个非常刺眼的白色亮点为止。最后，放置好载玻片，我就仔细的看了起来：显微镜下，洋葱表皮变得十分大。一个个六边形的小块组在一起，边上还有个大气泡呢！还没看完，我就被顾丽娜推到了一边。她一边看还一边说：“让我看一下，你一边去。”
这次的科学实验既有趣，又让我们看到以前从未看到过的东西，真是很有收获呀！
❺ 求英语作文 一个有趣的实验急急
是这个吗？说吧点燃的蜡烛摆在水中，再把玻璃杯盖过蜡烛，过一会蜡烛熄了，水就上升。 Today our teacher got a candle. She put it on a stand, in a basin, with coins beside it. Then she put a glass jar full of air over the candle. She put some water in the basin. Our teacher lit the candle. The candle stayed lighting in the air for a while and bubbles appear in the wate. Then the candle went out. Now because the jar was empty and all the air was used up the water rushed in to fill the space in the jar. Look at all the water that rushed into the jar to fill up the space that the air used to take. 很开心帮到你。

❼ 科学实验为题的英语作文80字
In ancient times, many people believed the earth was a flat disc. Well over 2,000 years ago; the ancient Greek philosophers were able to put forward two good arguments proving that it was not. Direct observations of heavenly bodies were the basis of both these arguments. First, the Greeks knew that ring eclipses of the moon the earth was between the sun and the moon, and they saw that ring these eclipses, the earth's shadow on the moon was always round, they realized that this could be true only if the earth was spherical, If the earth was a flat disc, then its shadow ring eclipses would not be a perfect circle; it would be stretched out into a long ellipse. The second argument was based on what the Greeks saw ring their travels. They noticed that the North Star, or Polaris, appeared lower in the sky when they traveled south, in the more northerly regions, the North Star appeared to them to be much higher in the sky. By the way, it was also from this difference in the apparent position of the North Star that the Greeks first calculated the approximate distance around the circumference of the earth, a figure recorded in ancient documents says 400.000 stadium, that's the plural of the world stadium. Today, it's not known exactly what length one stadium represents, but let's say it was about 200 meters, the length of many athletic stadiums. This would make the Greeks estimate about twice the figure accepted today, a very good estimate for those writing so long before even the first telescope was invented.
