I love science middle school students' compositions (1) When my father told me a story, a listed company in Shiyan City, Hubei Province held a celebration party. Fifteen red-billed love birds flew into the air and danced, but when the ups and downs of music started, love birds fell to the ground and died. Composition-I love science. Why is this? Many experts invited later failed to explain this phenomenon, and finally found the answer with the joint efforts of biologists and physicists. It turns out that the ups and downs of music are a kind of noise to love birds, which destroys the nerve center of birds and is the direct killer of birds' death. At that time, I vaguely planted the seeds of science in my mind and wanted to be a scientist when I grew up. As I grow older, I gradually know that science is knowledge and power.
Science can help people solve difficulties and change their lives. When Edison was a child, once his mother was seriously ill and needed an operation at once, but the hospital was too far away from his home, which would delay his illness, so the doctor decided to have the operation at their home. But there was no electric light at that time, and the indoor light was too dim for surgery. Little Edison used his quick wits, made several big mirrors, adjusted the angle to the light, reflected the light to the temporary operating table, and the operating table suddenly lit up. The doctor successfully completed the operation and Edison's mother was saved. This is the power of science. Later, Edison finally invented the electric light through his own continuous efforts and exploration, which brought light to mankind. When Edison died, people all over the country turned off the lights in memory of him. That night, even the torch held high by the Statue of Liberty went out.
I am curious about science and want to be a small inventor. One Sunday last semester, my brother Guo and I went to the experimental class of Little Newton. This time, I made an astrologer. The teacher explained a lot of knowledge about constellations to us, and then gave us equipment. Then we started our own invention. First, a piece of paper was punched with many small holes according to the mark of the star map, and the star map and half a piece of hard paper were glued together. Then two dry batteries are fixed on a large piece of foam plastic with double-sided tape, and the wires are welded to the small bulbs and batteries. Finally, put a small light bulb on the bottom of the paper cup, and stick the star drawing on the foam plastic with double-sided tape to complete the star map. After I finished, I showed the fruits of my labor. I was dumbfounded when I saw the clear constellation pattern on the wall. I am surprised and excited about this strange phenomenon. I have always kept this little invention and made unremitting efforts to become a small inventor.
Science is a double-edged sword. Good people use it to benefit mankind, and evil people will use it to destroy our home. I love science. I want to be a scientist, serve mankind with science, make our life better and the world better!
I love science students' compositions (2) Science is an indispensable part of modern society. He is everywhere, from our side to the mysterious universe. How desirable it is. I deeply love science.
I love science, and I love looking for science even more. My grandfather's house has three boxes of bees. There, it became my stronghold to find science. There, I watched such wonderful scenes as "worker bees carrying pollen", "queen bee patrolling" and "beating wasps", and the battle of wasps impressed me the most. That day, Wai and I were feeding syrup to bees. When the little bee was eating with relish, a wasp appeared out of nowhere. Like a sharp arrow, it rushed at the bees. Grandpa and I immediately stepped back and watched the fire from the other side. At first, wasps were unstoppable. When a worker bee came, it killed one, and a dozen worker bees died at once. But later, a group of brave worker bees surrounded the wasp and kept flapping their wings, making a "Weng Weng" sound. After a while, the worker bees dispersed, leaving only the body of the wasp.
I felt very confused and went home to find the answer. I found out all the books about science at home, and then I was in pain. I want to turn over all the books in front of me. Although I really want to give up at this difficult time, my love for science has always encouraged me to move forward. So, I made up my mind and spent an afternoon reading, but I found nothing. I began to lose confidence. When I saw the computer beside me, I thought of a trick-surfing the Internet. As soon as I started, I immediately entered the internet, trying to find the answer in the vast network. Many things happen, and I am interested in finding the answer. It turns out that worker bees flap their wings to raise the temperature and heat the wasp to death. According to the data, wasps can tolerate the high temperature of 43 degrees Fahrenheit, and worker bees can tolerate the high temperature of 45 degrees Fahrenheit. When the temperature rises to 43 degrees Celsius, the wasp dies, but the worker bees can still survive, which is the key for the worker bees to win. Wow! I was really happy when I found the answer by myself.
I love not only looking for science, but also doing scientific production by myself. Usually, whenever I have a whim, I will make a small production. Every time I shoot a small production, I always encounter some troubles. I will explore slowly and find a way to solve it myself. When you finish your work independently, it will always make you feel happy and make you fall in love with science unconsciously.
This is the charm of science, this is the soul of science, and this is the endless fun that science brings to people. Therefore, I love science.
I love the composition of middle school students in science (3) Interesting anime stories, fascinating computer games, EMU trains, GSM mobile phones ... These series of products have come out one after another, but do you realize that they are all attributed to the great power of science and technology, which not only changed the world, but also changed our lives. Science and technology are always around us.
In the past, people lived in a dull material world and only pursued food and clothing, without higher spiritual pursuit. No telephone contact, only letters; There are no planes and trains, only carriages and walking; People live in low-rise bungalows without tall buildings.
Nowadays, the rapid development of science and technology is not only beneficial to work and life, but also opens up a broad world for our teenagers to love and use science since childhood. Computer courses are offered in primary schools. Through the study of computer course, I understand that calculator is a bridge and tool to science, and it is also our good spiritual food. I can look up information in the computer, communicate with children all over the country, learn knowledge that books can't, draw a blueprint of the future world in my heart in my calculator, and describe my beautiful dreams. ...
Today's era is an era of scientific and technological competition. Who is strong among countries and who is capable among people depends on who is leading in science and technology. The older generation of scientists promoted the development of science and human civilization with their outstanding contributions. After the founding of New China, China's science and technology developed with each passing day: hybrid rice, the explosion of atomic bombs and hydrogen bombs, the launch of satellites and so on. These remarkable scientific and technological achievements have greatly shortened the gap with advanced countries and injected vitality into the vigorous development of China.
With the rapid development of science and technology, science not only serves the cutting-edge science and technology, but also permeates our study and daily life more and more.
Last year, I feasted my eyes on the robot contest for high school students and college students held in Northwest Normal University and other places: sophisticated robots, cars without fuel, virtual soccer competition, high-tech information transmission and so on, all of which are vivid and interesting phenomena and full displays of science and technology. While studying science and enjoying a new life, we pay more attention to creating a new life. Nowadays, the application of scientific and technological products has undergone earth-shaking changes. LCD TV, computer surfing and GSM are household names, and technology has played an endless role in different fields.
The wisdom of human beings is infinite. Whether it is about the universe or about social development, it shows the progress of human science and technology. Marx's basic theory that "science and technology are the primary productive forces" has inspired many people who love science and technology, and their scientific research achievements have inserted wings for the take-off of our motherland. Now, let's also use it to motivate ourselves, be a century teenager who loves science, shoulder the heavy responsibility of the new century and write a better chapter for the future of the motherland!
