Teacher asked to write an essay on the natural reflection of science 200 300 words how to write 20

I also want to learn from scientists, take inspiration from animals and plants, and design small inventions. Nature is the teacher of man, and scientists have learned many things from animals and plants. For example:

In the past, the TV tower was not strong, the violent wind could fly 80 meters away in one second, like this wind, it may blow the TV tower down, people got inspiration from the cedar tree, and built the TV tower like a fir tree, so it would be good, no matter the wind and rain, the TV tower could not fall; Scientists also got inspiration from sharks, inventing swimsuits, reducing the resistance ...... waterI also want to learn from scientists, take inspiration from animals and plants, and design small inventions. The gecko's hands and feet are very attractive and can easily climb up the wall without falling off. I'm going to design a shoe that looks like a gecko's hands and feet, and the name of this shoe is "Suction Invincible".

It is convenient, when the worker paints the wall, you don't need to bring a ladder, you only need a pair of "suction invincible" shoes to start work, it not only adsorbs, but also reduce your weight, even if you brush the wall upside down, there are two buttons on the right side of the shoe, press the green button, it can let you move up and down on the wall, never fall down, press the red button to come down. Do you find it convenient? When I really invent "Suction Invincible", I will definitely give it to the workers who clean and build houses.

For example, ants move swallows fly low.

Whenever I stand on the main road and see a traffic light, I wonder why the intersection lights are red, yellow and green. With this question, I have asked many people, but the answers have not been satisfactory.

A few days ago, I searched the Internet and found a lot of information about the three colors of red, yellow and green. Optically speaking, red light has a longer wavelength, which makes it easy for people to spot it far away from the indicator light; The yellow light has strong light penetration, is more eye-catching, and can give people a reminder; Green light is a very environmentally friendly color.

Sir Isaac Newton (25 December 1642 – 20 March 1727 in Julian calendar, 4 January 1643 – 31 March 1727 in Julian calendar) was a mathematician, scientist, and philosopher, as well as a keen alchemist in England at the time. His law of gravitation, as well as his Newton's laws of motion, in his Mathematical Principles of Natural Philosophy, published on July 5, 1687, are the cornerstones of classical mechanics. Newton and Leibniz also independently invented calculus.

In total, he left behind more than 500,000 words of alchemical manuscripts and more than 1 million words of theological manuscripts.

Newton is known as one of the greatest scientists in human history. For the first time in human history, his law of universal gravitation unified the motion of heaven and earth, providing strong theoretical support for heliocentrism, and enabling the study of natural sciences to finally break free from the shackles of religion.

Newton also discovered the color composition of sunlight and built the world's first reflecting telescope.

Life is precious, but it is fragile, and the slightest injury can mutilate or terminate it, like a veil of light. The boutique learning network has compiled a 200-word safety knowledge essay for everyone: safety education experience, and I hope that students can pay attention to safety.

This Saturday, I watched a TV show on safety education. The program is divided into five sections: **, Fire, Drowning, Flooding, and Traffic Accidents. I focus most on the part about traffic accidents.

Traffic accidents are about safety on the road. For example, don't chase and fight on the roadway, don't ride on the roadway, stop a vehicle, and don't climb over the railing in the middle of the lane.

The main things to prevent fires are: don't light candles and read books at night, and don't play with open flames. If you find fire on your body, you can't run fast but roll on the ground quickly.

**When coming, you should protect your head, quickly hide under objects that are not easy to collapse, if you are buried under the rubble, do not shout, use tapping to attract the attention of rescuers, if possible, you can properly replenish food or water, etc.

I learned a lot of safety knowledge in this program.

This is the end of the safety education experience, I hope that every reader can understand safety after reading, life is precious, but also fragile, we must pay attention to the safety of themselves and their families!

Whenever I get close to you, my restless mood will disappear without a trace, and my mood will be as peaceful as autumn water; Whenever I get close to you, my complicated thoughts immediately become neat and orderly, and you make me have a thinking space as wide as the sea and the sky; Whenever I get close to you, my paradise overflowing with the fragrance of books, my heart seems to travel to a paradise, and I am deeply fascinated by the ...... thereWhen I was younger, I loved to fall asleep with the hard shoulders of a book. I like to smell the special ink smell of offset pages. The years passed quietly, like a dream.

The pages of the books that exude the fragrance of books are turned one by one, and my annual rings are constantly whirling.

Natural science is the understanding and summary of the laws of nature by human beings, which gives people reason and wisdom, and helps people say goodbye to ignorance, get rid of superstition, and move towards civilization. By popularizing scientific knowledge, establishing scientific thinking, carrying forward the spirit of science, mastering scientific methods, and relying on scientific development, our society will be more civilized and progressive, and our country will be more prosperous and powerful.

The germ of science has ushered in the dawn of human civilization, and the development of science has promoted the progress of human society. With the accumulation of knowledge, human beings have become more and more capable of using nature and transforming nature, and science has penetrated more and more extensively and deeply into people's work, production, life and thinking.

Science and Nature 500 words.

Time flies so fast, the winter vacation has begun, this afternoon, everyone went to get the results, by the way, we also received gifts from the teachers of each subject. Today, I plan to recommend a good book to all of the class, titled: Science and Nature.

It's a series of books in the Baby Bear series, but don't underestimate it, it's a full 192 pages! It's not the kind of book series that talks about muffled wisdom very thinly, only more than 20 pages long, and it's a little heavy. Character Profile:

Scientists know bears, he is a first-class bear scientist in this era! Little cute little bear sister, she is a first-class bear cutie in this era! Brother Little Bear, he is a first-class bear in this era, and he is a good little clever!

Kind-hearted mother bear, she is the first-class bear kindness of this era! Super funny Papa Bear, he is the first-class bear of this era, super funny! There are three themes in this book, and they are all interesting, and these three themes are:

The Bear Kingdom calendar also includes a walk into nature, and finally a science fair. The first theme, the Bear Kingdom Calendar, focuses on the four seasons of the year and all the festivals of the year.

The second theme, "Into Nature", is mainly about the many animals in nature and the many plants in nature, as well as our home, the earth itself. The third theme, the science fair, is about the myriad machines in science. How do they work?

Fun experiments in science and super funny Papa Bear in science. I love this book, I have read it three times, because this book can make us happy and happy to learn scientific knowledge on interesting and interesting premises. I hope that after reading this tree, you will enjoy this fun and knowledgeable book as soon as I do!

Stephen Hawking, a hardened scientist. From Hawking, I learned many truths and engraved them in my heart.

At the age of seventeen, Hawking was admitted to the prestigious Oxford University, but at the age of twenty-one, he suffered from atrophic lateral sclerosis, lost the ability to speak, and was confined to a wheelchair with only two fingers to move. This is unimaginable and unbearable for the average person. But Hawking did not bow to difficulties, he bravely challenged fate with amazing perseverance and tenacious spirit.

Eventually, he succeeded and became a Fellow of the Royal Society, a professor of the Lucasson Chair in Mathematics that only a great scientist of Newton's might could make. His book "A Brief History of Time - From Big ** to Black Hole" shocked the world, with a circulation of 10 million copies.

Stephen Hawking's life was extraordinary, and he gave people great encouragement and made those who wasted their time regretful. After learning about Stephen Hawking, I often ask myself: Isn't Hawking's indomitable life, giving those people with disabilities the courage and strength to live, not enlightening us healthy people?

This makes me feel that we healthy people should not hesitate, we should not waste our time, we should cherish this beautiful time, cherish this happy life.

Stephen Hawking's deeds have made me profoundly realize that whether a person can achieve success or not depends not on the quality of his living conditions, but on whether he has the spirit of struggle. Usually, some people always use poor conditions and difficulties as reasons for self-comfort, and they also use these "reasons" to evade responsibility.

But how insignificant these difficulties are compared to Hawking! As long as a person has lofty goals and ideals to strive for, he will have endless strength, will not be bound by objective conditions, and will be able to give full play to his potential strength, often suffer from superior conditions, and dominate the world of his own.

I thank Stephen Hawking for making me realize these truths. I will definitely remember his words, do more meaningful things in life, and learn from his strong spirit!

On the weekend, I had nothing to do, I flipped through the "Science Reader" I just bought, I really didn't know if I didn't read it, I was shocked when I read it, I found some interesting little science in life, I decided to practice it, to see if it was accurate.

Other experiments were too difficult to do, so I made a relatively easy "beer shoe shine". First, I put the shoes that I had stepped on countless dirty West shoes into the basin and prepared the beer; The experiment began, I opened the beer and filled it with a full bottle.

They all poured in, and silently read while pouring: "Dad, I'm sorry, I haven't had a beer for two days." "I took the brush in my hand and poured beer on my shoes, and after thirty minutes I washed them and put them on the balcony to dry.

In the blink of an eye, it was already sunset and dusk, I came to the balcony, and looked at it, yo, this is my "broken shoes", it is simply a new pair of shoes, ha, I can wear "new shoes" in the future! I jumped three feet tall with joy.

Mom and Dad went out and came back, and I taught them this method, and they praised me as a little scientist.

The science in life is endless, and it is really worth exploring!
