A person's growth depends on science, and the progress of a society depends on science. It can be seen that science has a great influence on our society today. We should love science from primary school. In 2 1 century, science will become human life. If you don't know science, you can't survive in this society. If you have a scientific seed and cultivate it carefully, it will take root and sprout with time and bear countless fruits. The Nobel Prize in Science is such an award that inspires people to love science and create a better life with science. 466 scientists from more than 20 countries won the Nobel Prize. When they walk to the podium of the Nobel Prize, they represent that they have great wealth created by science.
Therefore, we should study science, love science and show science. But how can we do it? Scientists tell us that curiosity is one of the most important aspects of human nature and the main driving force for exploring scientific mysteries; The best way to satisfy this strong desire is to have the courage to ask why, to try and innovate, to overthrow the previous words and conclusions, and finally to get your own results. For example, Galileo, Copernicus and others bravely pointed out the wrong arguments of their predecessors regardless of pressure and opposition from all sides. Through personal practice and experiments, I proved that my point of view was correct and gained my own success.
Science is like water, nourishing people's hearts; Science, like eyes, can discern all the truth; Science, like a skillful hand, can create many magical things. Young friends should master the energy of water, the discerning ability of eyes and the creative ability of skillful hands, and believe that the future society will be beautiful.
Science is like a lamp.
"Science is not only beautiful, but also wonderful." This is a sentence that Professor Wang Zhihua told us in class. Let's start this one-and-a-half-hour course with this sentence as the topic.
At the beginning of class, the teacher put forward three requirements for us: first, communicate and interact to express our feelings; Two: no pen and ink, no reading; Three: enterprising, growth, sunshine. A sentence appeared on the big screen: "One stage, one game." The teacher also wants everyone to understand that the sun is new every day.
Soon, the teacher typed these lines on the big screen: "Attitude towards a Gu Song; 1, practical attitude-meaning 2, scientific attitude-knowledge 3, artistic attitude-emotion. To treat science, we should understand, appreciate and practice. Science can be appreciated. This is to make us take science seriously. Soon, a picture appeared on the screen-"Athens Academy", which contained many great scientists, such as Plato, Raphael and Aristotle. The man who painted this picture is Raphael, one of the important figures in the Renaissance. However, such a great man only lived for 37 years. He was buried in the Pantheon with the largest dome in the world.
The next celebrity is Galileo, who observed the sky with his telescope in 1609. He is also an amateur painter. After his death, he was buried in the Pantheon, built at the end of 15, with a height of 98 meters.
Newton, who died in 1727, said: "Diligence, diligence, and diligence." He was buried in Westminster Abbey after his death. We finally said this sentence: "Look at science with a comprehensive attitude and look at life with a comprehensive attitude."
The last sentence points out the theme, and we must treat science with a noble heart and a comprehensive attitude. Science has brought a lot to mankind, and everyone should have special courage in pursuing science. Science is not only a discipline, but also a part of life. Only passion can explore science, ability can understand science, and talent can discover science. Science is an art, and we will make unremitting efforts to explore the truth, so that the stories of scientists such as Newton will remain in our hearts forever.
You should get more knowledge from science before you explore it. Books are your good teachers. Galileo loved reading all his life, which made such a great scientist. Science is everywhere. Exploring science can increase our knowledge and contribute to our future study.
Finally, I hope science can be with us, and I hope everyone can like and love science. You can pursue science more in your later life and "look at life with a comprehensive attitude!"
I really want to swim in the endless ocean of science and invent many instruments to help mankind and make those poor people no longer suffer. Let each of us fly in the universe. Therefore, from now on, I will study hard and become an excellent scientist when I grow up.
On the earth where we live, many people cut down trees for their own benefit, causing one ecological disaster after another. If you cut down all the trees on the earth, you will have more money in your wallet, but have you ever thought that if there are no trees on the earth, the air will be reduced, and how can we live without air? At that time, it will be too late for you to save money, so I want to be a scientist and invent some energy-saving tools so that they will no longer be confused by money, but let him create unlimited resources with limited resources. I won't let the last sigh of the world turn into a cry.
In the future, I will certainly invent many energy-saving and environment-friendly instruments to make our sky more beautiful, rivers clearer and the sky fresher. Let the poor stop being poor and let them know that everyone is equal.
If I really become a scientist, I will make the dream of flying to the universe come true, so that everyone can see every star, let them appreciate the beauty of the earth and let them know that our earth is lovely.
I hope my dream can come true and I can see our earth. ...
I really want to be a scientist, but scientists can also invent practical things. Serving people makes our life very convenient.
If I become a scientist, I want to invent a house called "Gravity House". In this room, people can jump high without gravity. Can't say there is no gravity at all. By rights, gravity still exists. If there is no gravity, it will be much more troublesome for people to stop in mid-air. Its gravity is still a little.
If I become a scientist, I will invent a kind of warm clothes, which can change the temperature of clothes from hot weather to cold weather. You can also change the shape, so that people are not monotonous to wear. In this way, we can only wear one coat You can save money and buy more coats, which are not monotonous and warm to wear.
If I want to invent a machine to eliminate fatigue after I become a scientist. This machine can make people's fatigue disappear without a trace. But may there be side effects when this machine is invented? Can not be used for a long time, it is not good for your health.
If I really become an excellent scientist, what I said can still be realized. If I don't become another scientist, the consequences can be imagined. I will study hard now and become an excellent scientist when I grow up!
My mother is a middle school chemistry teacher and may be influenced by her. I like doing small scientific experiments since I was a child. I remember when I was in grade one, my mother bought me a copy of Children's Science Experiment 100 Case. I have been reading books all day and have done many interesting experiments!
On Sunday, after finishing my homework, I picked up the book Children's Science Experiment 100 Cases and looked through it. Suddenly, several big characters came into my eyes: "homemade rain doll". "ah!" I cried with joy and immediately danced with joy. Yes, do this little experiment!
I first found a plastic doll according to the requirements in the book and washed its body with soapy water. With the help of my mother, I made a white dress for the doll. Next, we need to find a chemical called diamond dioxide, which happens to be some at home. I pour a little diamond dioxide into the beaker, then add distilled water and stir well until the solution is pink. I soaked the white skirt in the solution for a while and took it out to dry. I put the finished skirt on Wagui and on the windowsill, but I tried it for a few days. Although the weather has changed, the skirt has not changed color. Why? Oh, the reason is found, because the skirt is not dry but dry, no wonder it doesn't change color! Failure is the mother of success, and I am determined to do it again.
My mother and I made a white dress for the doll as it is, soaked it in diamond dioxide solution for a few minutes, and then took it out and put it on a plastic plate to dry. Gradually, the skirt turned light blue. I looked at the weather, and it was sunny. I dressed the doll and put it on the windowsill. The next morning, I first ran to see the weather, well, cloudy, and then looked at the skirt, which turned pink. "It worked! Success! " I jumped for joy.
Why does the skirt change color? Is it magic? Mother said, "Diamond dioxide is a chemical substance, which contains pink and blue pigments." When the air is wet on cloudy days, the diamond dioxide absorbs water, and the blue color is rejected, so the color turns red. On sunny days, the air is dry, the water evaporates, and the red color is eliminated, so the color becomes blue. "I looked at the small production and couldn't help but blurt out:" How mysterious science is! "
I benefited a lot from this little scientific experiment. I think: No matter what you do, as long as you have perseverance and are good at thinking, you will certainly succeed.
In this world where technology is advancing by leaps and bounds, we live happily, because love is warming the world and the sun is shining on the earth. Childhood is still brilliant. But since-was born, the seeds of sin and death began to take root and sprout all over the world.
For this reason, how many people are separated, how many people are homeless, how many people are killed, and how many people are miserable. Indeed, like the devil, it destroys us mercilessly.
No matter how exaggerated you think it is, no matter how ridiculous you think it is, that's the truth. Who would believe that Liu Siying, a lovely and sunny eight-year-old girl, could go to the square if she didn't see it with her own eyes? Who would believe that all this came from her favorite person-Liu Siying's mother? But this scene happened, and the mother and daughter were full of happiness and happy hope, but they came to the home of death. Burned alive by the fire. When I read this, even I was shocked, as if death were cutting the thread of human life with a sickle, showing a ferocious and terrible smile, which made my hair stand on end.
Yes! If we don't love and oppose science, it will deceive your eyes, corrode your soul, poison your body and make your tomorrow full of darkness. Therefore, we must learn to arm ourselves with scientific knowledge, so that we can have the strength to fight to the end. Let the darkness that is eroding the world disappear forever and build a better and more prosperous motherland!
Finally, please let me appeal loudly: "No matter who you are, no matter who you are, please stand up.". For our tomorrow, for the future of the motherland, love science and oppose science from now on! "
If there is no ideal, life is like a ship without rudder, drifting without direction; If there is no ideal, life is like a headless fly, buzzing and bumping around; Without ideals, life is like a pale surplus with broken wings, stumbling and lacking goals. My ideal is to be a scientist.
Every time I see the inventions of such great scientists on TV, I have an ideal in my heart: I want to be a scientist who has a great influence on the scientific community like Einstein, Galileo and Newton, invent many great inventions, become a celebrity in the scientific community and win glory for the motherland.
Of course I know it is not easy to be a scientist; You should have a high degree, a strong thirst for knowledge and imagination, and a spirit of not being afraid of difficulties and failures. "Is it naive for a child to think of Japanese scientists?" Yes, it sounds childish, but I firmly believe that "with perseverance, the iron pestle is ground into a needle."
First of all, I want to study hard and get a good degree. Set aside two hours every day to read a lot of books about science. Learn about the inventions of many scientists and how to make such inventions. Then I will collect some alarm clocks and toys that are not used at home, carefully remove every part of them, explore the composition principle of these things, and then put them on one by one. Finally, I will cultivate a pair of eyes that are good at discovering, and the ability to see the details of things, ask questions and keep exploring. Every success is a pair of eyes that are good at discovering. Sometimes opportunities pass us by, and whoever has the will can catch him; Whoever is willing to work hard can succeed. If there is any accidental opportunity for scientific discovery, then this "accidental opportunity" can only be given to those who are prepared, to those who are good at independent thinking and to those who have perseverance.
I have the confidence to break through all difficulties, pursue my ideals, realize my ideals and win glory for my motherland.
I really want to be a scientist, because scientists can make great contributions to mankind.
If I were a scientist, I would make a micro robot. Although this robot is only half the size of a coin. Although he is small, he is of great use! It can enter the human body and suck the tumor in the human body.
The dean of a big hospital came to me and said, "There is a strange patient in my hospital. The patient said he had something in his nose. I saw a big tumor. I read about your invention in the newspaper. So I came to you to treat this patient with your invention-micro-robot. I used the remote control to drill into the patient's nostrils. I pressed the yellow button again and the robot began to work. It can be clearly seen from the display screen that there is a needle-like little thing on the right side of the robot body, which is the tumor eliminator. The robot is already working, and the tumor is gradually shrinking ... and then shrinking ... Ah, it worked! I was so excited that I almost cried. Yes, I stayed up under the lamp for many nights and wrote many experimental papers to make this robot! I pressed the red button again, and the robot came out of the patient's nasal cavity smoothly, and it was intact.
"Does it hurt?" I asked. The patient replied, "It doesn't hurt at all." I am also very excited to see him so happy.
Science is boring for us now, even when it is mentioned, we will feel bored.
I used to hate science classes. I feel sleepy and want to sleep as soon as I start class. Teachers always take pains to talk about knowledge over and over again and do one boring experiment after another.
But last time I had a science class, I found the charm of science. That time, the teacher explained the microscope, and I was staring blankly at my desk. When explaining the structure of the microscope, the teacher said, "After a while, every student will go to the podium to introduce the structure of the microscope to everyone." At first, the students walked to the podium one by one, casually pointing to various parts and saying their names. But after a long time, the teacher didn't call me, and I felt very confused. A minute passed.
After a long time, the teacher smiled and told me, "There will be more difficult tasks for you in the future!" " ""At that time, I braced myself and thought over the teacher's words. Finally, I realized that this is the teacher's trust in me, and I have to be worthy of the teacher. After a while, the teacher called me: "Shi Yuxuan, please come to the podium and put the microscope back in the box in the right way." "When I heard this, I was particularly happy: normally, the teacher wouldn't let any student move the microscope, but today this task was given to me ... I walked onto the podium in fear and trembling, and carefully removed the eyepiece and objective lens according to the method taught by the teacher, put them in my schoolbag and put the microscope in the box carefully. Although this is only a few minutes, it contains the teacher's trust in me.
Since then, I have gradually learned about science and science. I find science so interesting that it makes me realize the meaning of nature and life. In the experiment, I found the pleasure of personal experience.
Now, I look forward to how interesting it will be to learn physical chemistry in the future!
The sixth grade science composition 10 science, this term must have been heard by everyone. For our life, science is everywhere. Today, I will tell you a popular science story around me!
That day, I played outside, went home, took a sorbet and ate while having fun. Suddenly, I saw a strange piece of glass, picked it up and looked at the mung bean on the sorbet. The result gave me a big fright. That mung bean seems to be a big ball! I quickly threw away the cup for fear that there was a "ghost" in it. But after waiting for a long time, the "ghost" didn't come out. I picked up the glass and looked at many objects, and found that the images of the objects were magnified many times. I saw a pair of glasses again. I picked them up and wanted to see if the effect was the same as this glass piece. As a result, when I saw it, it was a big ball, which scared me a lot. The image of that ball is as small as a mung bean! It suddenly occurred to me that I didn't enlarge or reduce the image of the object when I looked in the mirror! I ran to the mirror and looked. Sure enough, my image shows no signs of enlargement or reduction. Gee, why are these three situations so different? Why don't the images we usually see in the mirror expand or shrink? Why do glasses reduce the image of an object? Why does that small piece of glass make the image of the object bigger? Numerous questions came to my mind, and I immediately searched the internet for information.
The original mirror that can shrink an object is called a concave lens, which diverges light. A mirror that magnifies an object is called a convex lens, which can converge light. The mirror we usually use to look in the mirror is called a flat mirror, which is basically the same size as the original object. Our eyes are actually a convex lens. Plane mirror, convex lens and concave lens are three kinds of virtual images, all of which are upright; The real images formed by concave lenses and convex lenses are all inverted without exception. Of course, concave lenses and convex lenses can also form virtual images, and the two virtual images they form are also upright. The structures of concave lenses and convex lenses are also different. A convex lens is composed of a transparent mirror, and both sides of the mirror are ground into spheres. A convex lens consists of a transparent mirror, both sides of which are ground into concave spheres. Unexpectedly, they are so magical! Little body, behind it lies the truth!
Knowing this information, I feel that although the mirror is different, the essence is still the same. Later, I also tried to put the convex lens and concave lens together, and it felt as if I had directly brought the distant things closer! So this is the basic telescope, the basic body of galileo telescope! I accidentally built a telescope!
Science is so magical that our life is even more magical. Now, our school has a "maker" space about science. Do you want to come too?
