Sixth grade scientific composition 1 Our class is also a place where geeks gather. There are "Logger Vick" in the animation industry-Wang Jiadong, and the Monkey King-Mei Kaining who caused havoc in heaven ... but I admire Li Fangqi the most.
With a long nose and white skin, he looks like Mr. Bean. He not only looks like him, but also talks funny. Like Mr. Bean, he often does some ridiculous things. His eyebrows are up and down, he dances when he speaks, and he often makes his classmates laugh, so he is very popular with his classmates. At the same time, he also loves science, and I have deep feelings with him in the science group.
I'm not sure how much scientific wisdom Li Fangqi has in his mind. In class, he can always say questions that his classmates can't answer and always make unusual experiments.
I remember it was an abstruse and abstract scientific experiment class. What the teacher said was not very specific, so I was confused and other students didn't understand it very well. The experiment was far from starting, and everyone screamed, but Li Fangqi operated confidently. All the other members of us are sitting on the bench and doing the experiment. He is sure to win. Li Fangqi untied the wires and pinched one of them with two fingers. One hand touched the connector and the other hand turned the socket button. Li Fangqi has a serious face and is not careless at all. "MeiKaiNing! Bring me the light bulb! " With that, he carefully clamped a small glass bulb and screwed it into the lamp holder.
"You're finished!" Li Fangqi said happily. With so many wires, lamp holders and battery boxes of different sizes, can this small light bulb light up? We have some questions. It's time to witness fate-
"Cha-"I only heard Li Fangqi press the single-pole switch, and the small light bulb lit up slowly like a waking soldier. "Yes-"Li Fangqi made a victory gesture with a happy smile on her face. "This honor is mine, don't grab it!" We all laughed and admired Li Fangqi's cleverness. Therefore, our group's experimental results rank first.
Li Fangqi loves science and likes books on science. There are always some books about science in his schoolbag. It is because of reading science books that we often say scientific terms from his mouth that we don't know. In my eyes, he is like an Einstein, who will become a scientist when he grows up!
In our geek class, there is such a scientist who loves science-Li Fangqi, and I admire him very much.
Science, for us now, is boring, 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!
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!"
Chen Jing is my classmate. There seems to be a small motor on her head, which keeps turning. She loves science very much and is what her classmates call a "little scientist".
Chen Jing likes quiet, just like her name, but she is very active in science class. She likes to do small scientific experiments. Her interest elective package is like a small museum, with a magnifying glass, a compass, a small rocket, a small model airplane … everything. One day, the teacher finished the magnifying glass unit and just announced the class was over. She jumped up from the chair, took out a magnifying glass, and concentrated the sunlight on a piece of white paper. The light spot the size of a red bean is hard to see, but she still looks at it with great interest and carefully adjusts the focal length. "Smoke, it's working!" The sound startled the students around. Chen Jing held the smoking paper high, skipping, his eyes wide and his mouth closed. It's like discovering a "new world". But she suddenly frowned and rolled her eyes, so she took out a black pen and blackened the paper three or five times. I asked her what she wanted. She said to me, "Try the black one. Is it easier to absorb heat? " She continued to focus the light with a magnifying glass. After a while, the paper creaked, and a smell of paste came to my nose, almost burning. Just then, the bell rang, and she quickly packed up the experimental equipment and put it in her bag.
Last month, I suddenly found another thing in her bag-a small and exquisite homemade humidifier. I asked her, "Who made this thing?" "I did it in an elective course of interest." I used to think she was very quiet, but I didn't expect her to have such skill. I studied the humidifier carefully and asked her, "Does this work?" She said excitedly, "Don't you believe it? Then let's try it first? " With that, she put a small glass of water into the humidifier, then turned off the machine, turned on the switch and waited. She hummed a ditty and beat the time rhythmically, which seemed very leisurely. After a while, the humidifier sprayed wet white gas. Looking at this humidifier, Chen Jing grinned happily and said proudly, "Can I do it?"
Chen Jing was completely fascinated by science. She is really a "little scientist". I admire her very much! I believe she must be a woman "Edison" when she grows up!
Sixth grade scientific composition 5 sixth grade narrative composition: man and science
The development of mankind is inseparable from science, and the development of science is also inseparable from mankind; But everything is not perfect, and there are advantages and disadvantages. The development of science is like a double-edged sword, which has changed mankind and even the whole earth. Let's take a look at the advantages and disadvantages of scientific development to human beings and nature!
With the development of science, human life has undergone earth-shaking changes and become more comfortable and convenient. But at the same time, its negative impact should not be underestimated. For example, cars can save time and facilitate travel, but also make people's physical function gradually deteriorate due to lack of exercise, and the exhaust gas generated by cars will also destroy the ozone layer and pollute the air; Although the appearance of TV and computer can make people know information without leaving home, it also reduces the communication between people and makes medicine more advanced and developed. But because people abuse antibiotics, the resistance of bacteria to drugs is getting stronger and stronger, and one day, the invasion of bacteria will become unstoppable.
While enjoying the new life of science and technology, have humans ever thought about a series of ecological disasters caused by it? According to scientists' statistics, 23% of the world's arable land is seriously degraded, 50% of rivers and rivers are reduced or polluted, 25% of mammals and 12% of birds are endangered,14 of human diseases are related to environmental degradation,13 of the land is facing desertification, and 80 countries are seriously short of water, 65438. However, all these "environmental problems" are precisely the evil consequences caused by human beings, and these figures increase rapidly at an alarming rate every year.
The once beautiful earth, beautiful lakes and mountains, endless rivers, vast and spectacular virgin forests, crystal-clear lakes ... all these things no longer exist, and the culprit causing this serious consequence is human beings. Mother Earth, who is kind and beautiful, created human beings only to make the whole nature full of vitality and harmony, but we let her down too much and even broke her heart. If mankind continues, the consequences will be unimaginable! Shouldn't we be responsible for the consequences we have caused? Should we continue to harm nature? Will we continue to hurt our mother earth? No, we should take immediate action to remedy what we have done before. You should know: "being kind to the earth means being kind to yourself, and saving the earth means saving the future;" There is only one home, and the earth cannot be cloned! Act now before it's too late! "
There is a saying: "Science and technology change history, and knowledge changes destiny. When we enter the 2 1 century, we are entering a high-tech era. The progress of a country depends on the development of science and technology. " But at the same time, we should grasp the double-edged sword of science and technology to make human life better and more comfortable, and at the same time, we should avoid it from "hurting" nature. In fact, the development of science is beneficial and harmless. As long as we master it well, then human beings and nature will go hand in hand. The effects will complement each other.
In the long history of mankind, there are many scientists who serve mankind. They are the elite of mankind, pioneers and contributors to the development of social civilization and natural science. There are endless hardships behind each of them, and their life journey and struggle experience are certainly worth learning.
Their life is not happier than ours, their IQ is not higher than ours, and they have no help from the gods. They are just ordinary members. Then why did they achieve so much? Because they are constantly striving for self-improvement, they will never give up their persistent pursuit of their ideals.
Mao Yisheng, known as the father of bridges, had a dream of being a bridge architect since he was a child. For this dream, he studied hard, and finally one day, he was able to realize his wish. But when the bridge was first built, the government had no choice but to let him blow it up, because it was to prevent the Japanese from using the bridge. 12 On February 23rd, the new bridge of Qiantang River was blown off with a bang. Mao Yisheng swears: No bridge, no husband! For the purpose of repairing the bridge in the future, Mao Yisheng kept all the drawings, papers and materials of the bridge. He is looking forward to, finally looking forward to War of Resistance against Japanese Aggression's victory. By 1953, the Qiantang River Bridge was completely repaired, and he finally realized his promise.
Lin, a gynecologist, lost her mother at the age of 5 and lived with her father, stepmother and many brothers and sisters. I got good grades when I was a child, and I was the first in everything in my class. /kloc-at the age of 0/9, she has a dream to become a surgeon after graduating from a women's normal school. She decided to go to the Union Medical College to study in university, but just five years later, her father died of a cerebral hemorrhage. Later, he became the director of obstetrics and gynecology at Union Medical College Hospital. Soon after, the Japanese invaders occupied the hospital. She opened a clinic, and in less than six years, she had 8887 medical records. She has never married, worked hard for the health and happiness of women and children for more than 60 years, personally received more than 50,000 lives from all over the world, and saved countless patients and parturients. To this end, she has no holidays, no order in life, and no routine in rest.
In the long history of mankind, countless people have made contributions to mankind with the spirit of Mao Yisheng and Lin. They work hard for their ideals. I want to learn from them and become a shining star in the future.
