Sixth grade scientific composition

In life, work and study, everyone must have been exposed to composition, which can bring our scattered thoughts together. I believe writing a composition is a headache for many people. The following is my carefully arranged sixth grade 10 scientific composition. Welcome to read the collection.

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 must have a high degree, a strong thirst for knowledge and imagination, and a spirit of not being afraid of difficulties and failure. "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' inventions can bring people happiness.

If I were a scientist, I would invent an intelligent robot whose function is to bring happiness to people. This robot can be transformed into vehicles such as cars, planes, boats and bicycles, and can also be the background of mountains, highways, train tracks and pharmacies. This kind of robot can start by buying a few at a time. Tell these robots a joke first, even if the program is finished, then set who is the background, who is the prop and who is the protagonist, and you can start. After starting, the robot will divide the work according to the preset procedures and tell the jokes vividly. When friends come, they will laugh their heads off and feel better than themselves. This will be my first work after becoming a scientist, and its main function is just to relax people.

The main function of the second work is to relax people, which is different from the first one. The first one is spiritual, this one is physical, and it is also an intelligent robot. It has many tentacles, each of which is more flexible than a human hand. It can sweep the floor, mop the floor, wash dishes, pour water, throw garbage ... more importantly, it can prevent theft at night, and it is solar power generation, which can make people no longer tired. This is my second invention.

The third invention is the most important. It makes up for the shortcomings of the first two robots. What if the robot is broken? The third robot knows all the repair methods invented by these three inventions (including itself), and only needs to buy two at a time, so why buy two? If something goes wrong with a robot, you won't be afraid. If the first robot and the second robot break down, the third robot can repair it, and the third robot can repair it with another robot, so you are not afraid of problems.

I want to be a scientist. If I were a scientist, I would do many things. ...

Today, the science teacher arranged for us to go home and do an experiment: to explore the reasons why cactus is drought-tolerant. As soon as I got home, I prepared the experimental materials and started the experiment according to the teacher's requirements.

I first took out three paper towels and dipped them in the pool. Then carefully put these three pieces of paper on the plastic paper that is "receiving" the scorching sun outside, one of which is flat and the other is rolled into a small cylinder like a slender rod. Of course, you can't forget to wrap a layer of airtight small coat wax paper on the last paper towel. All right, you can rest. Ah! Don't leave at once, this is only half of the whole experiment, and the fun is yet to come! Everything is ready, except the east wind!

"One minute ... ten minutes ... fifty minutes ... sixty!" How time flies! It's time to uncover the secret! Excited, I hurried to the door and squatted next to three pieces of paper. I touched the first one first: fuck! After an hour of "sunshine bath", the first one was almost completely dry; The second one is much better than the first one, and it hasn't been finished yet; It's time for the third photo. I accidentally grabbed the third picture and the water dripped down at once. Oh, my God, an hour's exposure actually kept it from evaporating. I am so surprised!

The next day in science class, the teacher explained it to us, and I realized that it was because the paper was covered with wax paper that the evaporation of water was reduced. Just like the unique epidermis of cactus, let cactus reduce the necessary evaporation so as to survive tenaciously in the vast desert.

Through this interesting experiment, I not only understand why cactus is drought-tolerant, but also understand that there is science everywhere in life. As long as I continue to personally experience the process of scientific inquiry, I will certainly gain scientific knowledge and understand the true meaning of science.

Sixth grade scientific composition article 4 familiar ringtones, familiar classmates and teachers. But he is the only new face I have never seen before.

The average teacher with small eyes and rosy mouth and no glasses doesn't look serious at all, but he is an exception, with a straight face, as if someone owes him money. Classmates say he is the new science teacher-Hersey. Hersey. Is he the Hussein I think he is? Look at his smelly face, I feel cheated by Brother Xue. Alas, the future is difficult.

The old bell rang and the class began. I saw him walk into the classroom empty-handed, and his heavy footsteps and dark face complemented each other, which was a perfect match. He stepped onto the platform. Just now, the classroom was still a vegetable market, but now it has become silent. I looked at his face and felt like a little rabbit jumping. Even the breathing in the classroom has become smaller. It seems that this teacher is terrible.

Finally, he began to speak: "I am your science teacher ... Next, I will choose the class representative and the group leader." This is a voluntary raise of hands to see confidence and courage, and the class representative will raise his hand. " It seems that everyone doesn't know what raising their hands is, and they all bury their heads very low. Everyone is indifferent, and no one wants to be kicked out as soon as he takes office. He could only smile and had to choose the team leader first.

Finally, it was my turn in this group, but at this moment, both hands were raised at the same time, one was mine, and I looked at the other ... alas, it was the girl in front again. The teacher was surprised to see two people raising their hands. Then I thought about it, told me to stand up and asked me a question: "Who do you think is better?" I froze for a moment, and I replied with no confidence: "If you don't talk about me, then I just have no confidence in myself. Why should I raise my hand? " The teacher motioned me to say it again. This time, I said it out loud He said, "Is it because I didn't choose you that I didn't give you face?" I gently "hmm", so I became the team leader.

Then I suddenly found that this new face is also good.

The scientific community is full of miracles. Astronomical geography, brilliant. Today, I read the book "100,000 Why" and savored it. I found that there are many mysteries hidden in it, which makes me understand this scientific society better.

There are cultural articles, scientific articles and so on in the book "100,000 Why". It tells the magic of everything in the world and solves these unsolved mysteries with scientific methods. For example, our most commonly used straws, do you know why straws can suck liquid? Because when the straw is inserted into the liquid, both the liquid inside the straw and the liquid outside will be subjected to air pressure. When we suck through our mouths, the air in the straw will be sucked away by us, and the liquid outside will enter the straw under the action of atmospheric pressure, so that we can drink the liquid.

Now you know, this is how the liquid enters the straw. Through this book, I learned a lot about science, expanded my reading range and enhanced my knowledge.

Science is used in many parts of the world. It is the rationality and accuracy of science that created this developed world. Rockets ascend to heaven, planes carry people, etc., all because of the accuracy and greatness of science.

From now on, let's explore nature, discover mysteries, study together and become a little scientist.

Why do neon lights have colorful light? Why friction can generate electricity? Why does the elevator automatically rise and fall? These are all possible things that we often think of. Scientists invented these things to help us answer these questions, and there is a certain basis. It is the invention of these things that has improved our lives.

Science creates life, science changes the world, and science can do anything!

If I were a scientist, I would plant colorful peaches, which are big and round, including red, orange, yellow, green, blue and purple. From a distance, they look like a big hydrangea, just like the peaches stolen by the Monkey King in the Journey to the West. This kind of peach is not only beautiful, but also has many functions. The yellow part of peach peel has the effect of Yunnan Baiyao after drying and grinding into powder. Green tangerine peel cooked with soup is a particularly good beauty and skin care product. The blue skin can last forever if cooked in a pot, not to mention the purple part. Grinding purple skin into powder can treat cancer with good effect.

If I were a scientist, I would also like to invent a biscuit. When my parents' wheels are gone, this biscuit can be turned into a wheel, which will be much more convenient for my parents.

If I were a scientist, I would also like to invent a perfume. As long as I spray it, you will be as beautiful as a fairy.

If I were a scientist, I would also like to invent an environmentally-friendly purifier, which can suck waste gas in and then spit it out, make it something beneficial to human beings, make our home, the earth, a clean and beautiful world without pollution, and let people live happily here. But I know that to realize these wishes, we need to work together, and I will study hard.

Sixth grade scientific composition 7 "I succeeded, I succeeded, I finally succeeded in the experiment …" I shouted excitedly. There must be countless questions in your mind, such as: What succeeded? What experiment did you do? How did you do that? You are ... Don't worry, I'll tell you what happened!

On Sunday, the teacher assigned us a task: to do a small scientific experiment and listed several small experiments for us. As soon as I got home, I couldn't wait to open my notebook, which recorded several experiments, such as wax in water, pouring glass, needles floating on the water, breaking the water flow and so on. What should I do? After careful consideration, I finally decided to do a simple experiment-the glass is filled with water upside down.

I kept searching for all the materials: a cup, a piece of paper. The experiment began. I fill the cup with water first, then cover it with paper, and then turn my hand around. God, this glass of water seems to have turned into thousands of naughty children, scrambling to fly out of the cup and splashing. Well, this experiment failed. What is the reason? I did as the teacher said. I thought about it, maybe it's cold water, and maybe warm water is needed to complete the experiment. Full of confidence, I quickly changed a cup of warm water and followed the first procedure. At the exciting moment, I held my breath for fear of affecting the experimental results. I closed my eyes and said, "Amitabha, God bless me, I will succeed". Who knows that when the hand turns over, ah! It's ruined again What shall we do? It seems that I still need Baidu's help. I opened Baidu search and looked at the operation details carefully. Finally, it dawned on me that I needed a hand to press it, and then I turned it over and let it go. I have built up my confidence again. I poured a glass of cold water, then put my hand on the paper and made a gorgeous rotation of 180. Because of the previous two failures, I dare not take my hand away. First, my hand holding the cup moved slightly, and I felt that the cup firmly absorbed the paper. I slowly pulled my hand away without any outflow. This time, nothing happened in the first two times. I shouted and jumped excitedly: "Mom and Dad, come and see, I succeeded, I finally succeeded!" " "

My parents heard my crying and thought something important had happened. When they saw the results of my experiment, my father said to me, "It is not enough to do experiments. It is necessary to understand why this happened. " Yes, what is the principle? I checked the information again, oh! It turns out that the atmospheric pressure is playing tricks, because after the surface tension of water attracts the paper, the enclosed space formed by the cup is equal to the atmospheric pressure in the air, and there is no pressure difference, so the water will not overflow.

Through this experiment, I understand that scientific discovery is successful only after repeated failures. If you fail, don't lose heart and try boldly. If you try boldly, you will surely see the "light of success"!

After reading the whole book, what impressed me most was the topic centered on an earthquake, which made me better understand the occurrence and prediction of earthquakes. The principle of earthquake is simply that the rock suddenly breaks when it can't stand it. But we don't know when the earthquake will happen. How can we know in advance? Before the earthquake, animals may have some abnormal phenomena. Such as: cattle and sheep don't enter the nest, pigs don't eat, dogs bark everywhere, snakes come out of the hole in the world of ice and snow ... every household should observe and report any abnormality in time and be prepared.

The book says, how should we face the earthquake? 5. 12 Wenchuan earthquake, there is a school. At that time, they often practiced emergency evacuation when an earthquake came, so there were no casualties in their school. In fact, as long as we calmly, calmly and correctly respond to the earthquake, there may be the possibility of survival. There is a good saying: be prepared. Because of 5. 12, there is an emergency evacuation drill every year on 5. 12. If there is an earthquake, it is just like a drill. First of all, be orderly and go to the open space according to the teacher's instructions; You can also squat under the table or lean against the corner, because the corner can form a triangular space. However, it should be noted that never jump off a building when an earthquake occurs. If you choose to jump off a building, it is equivalent to choosing suicide. After the earthquake, never go back to the house to get anything, because there will be many aftershocks after the earthquake.

After reading this book, I really benefited a lot I learned a lot of scientific knowledge. If you read more books of this kind, you will be inspired. Let's develop in a scientific direction and work hard for a better tomorrow!

Our life is colorful, but who makes our life colorful? Of course, he is a scientist known to women and children. They have devoted their lives to science, created many things for us and provided convenience for mankind. My greatest wish is to be a scientist.

If I were a scientist, I would create a robot. This robot can understand every word people say and is proficient in languages all over the world. It can replace the police and reduce casualties in violent incidents. In daily life, we can help parents discipline their children, help students learn, and cultivate good students who don't ask, don't understand, and are responsible for their work, so that teachers don't have to worry about students talking in class and getting poor grades anymore!

If I were a scientist, I would convert the copier invented by other scientists into a second kind of ultra-small copier, which is exactly like a mobile phone and has two functions. On the one hand, it can be used as a smart phone, and on the other hand, it can copy what people want to copy. The copier can not only copy paper documents, but also copy various items.

If I am a scientist, I want to develop a cheap spacesuit, which can automatically adjust the temperature at any time, so that people will still be very cool in summer and warm as spring in winter. As for why it is called a spacesuit, it is because it can walk as usual in a place without gravity.

If I were a scientist, I would make a protective cover, take the time machine I invented, go back to the past, and leave the Yuanmingyuan to today, so that people in the future can feast their eyes. ...

Although these are just my naive fantasies, what a wonderful wish! I must study the knowledge in front of me seriously and lay a solid foundation for achieving my goal!

If I were a scientist, I would invent something that would change history.

In the 1930s, I will invent a time machine, which will use the gap in the universe to expand and let me go back to the past, from a few minutes and hours to thousands of years and tens of thousands of years. For example, we can transport the atomic bomb and other weapons to Yuanmingyuan through the time machine, beat the British and French allied forces around, and protect our Chinese treasures, so that China can avoid spending tens of thousands of dollars on Yuanmingyuan cultural relics, China can have one more wonderful garden, and we can have one more national treasure.

If we can adjust the time machine to Jurassic, see the heroic posture of dinosaurs and witness how dinosaurs died out, we can solve this eternal mystery.

If I were a scientist, I would make a three-purpose car that can travel in water, land and air. If you want to go into the sea, press the blue button; If you want to go to heaven, press the white button; If you want to go by land, press the brown button. No matter in the sky, underground or in the sea, you can drive freely and conveniently with a click, without worrying about traffic jams.

If my wish can come true, how wonderful the world will be!
