Do you know how to insert the wings of science and write an excellent composition? In daily study, work and life, everyone has dealt with writing. With the help of words, people can reflect objective things, express their thoughts and feelings, and transmit knowledge and information. The following is an excellent composition with the theme of inserting scientific wings and flying for everyone. I hope you like it!

I love science. Science can make people fly into space to explore the mysteries of the universe. Or create all kinds of weapons with particularly strong destructive power. Reveal the lethality of animals. Treat various diseases ...

Science makes people fly into space, look for aliens and solve the mystery of flying saucers. And measuring whether Mars can be inhabited by humans. After about 100000 years, the earth is likely to be uninhabitable and need to find another place to live.

Other countries want to go to war with China. We should prepare advanced weapons, prepare to defend the country, prepare nuclear weapons, atomic bombs and other weapons that are more lethal than car seats to defend the country.

Without science, how can there be computers, televisions, refrigerators and air conditioners? What would the world be like without science! Science equals knowledge. No school, no country. No cooked food, no fashionable clothes to wear. What a terrible world this will be!

What a terrible world it would be without rice and fashionable clothes!

Science can also reveal the lethality and defense of insects, knowing that chameleons can change color, dragonflies can drink water, and snakes can bite and be poisoned. ...

I have done two interesting scientific experiments. Put an egg in a basin of clear water, put salt hard, and the egg will float. Another experiment, put some dry ice in hot water, there will be a fog, which is beautiful.

I love science.

On a sunny morning, our classroom is very lively.

Teacher Chen took out two balloons for two male students to blow, only to see them bulging their cheeks and blushing. The teacher asked, "What does a balloon look like?" Some say it looks like a peach, some say it looks like a red apple, and some say it looks like a pink bomb. Then the teacher took out a white thread to tie the balloon, and then used a magnet to attract the balloon to the blackboard. Looking at Mr. Chen's strange behavior, everyone is discussing: "What medicine does Mr. Chen sell in the gourd?" Just when everyone was wondering, Teacher Chen called a female classmate to the podium and rubbed the balloon with her long hair. In the process of rubbing, the students are thinking: will the balloon explode? The girl who wiped the balloon covered her ears and closed her eyes in fear that the balloon would explode. The students below us are also worried about the balloon explosion.

Something amazing happened. The rubbed balloon and another balloon fought like people. Everyone cheered when you pushed me and squeezed me. The teacher said, "It's not good to fight. Let's separate them!" " "I saw Mr. Chen put an A4 paper in the middle to separate them, and they hugged each other tightly. The teacher took A4 paper away and they started fighting again. It's amazing!

Science is really interesting, and there are many mysteries waiting for us to discover.

Plug in the wings of science and release the theme. Science is everywhere, and there are many examples related to science around us. I pay special attention to these interesting science stories around me and often personally verify the authenticity of science.

I did an experiment before: I poured some white vinegar into a cup and put a dirty coin in it. Twenty-four hours later, I took out the coin. The dirt on the coin disappeared and the coin became very clean.

I asked my mother, why can coins become clean? My mother told me: "because the coin has been used for a while, its surface will have an oxide layer, which is alkaline, and white vinegar contains acidic substances, which can wash away the alkaline substances, so the coin becomes clean."

Do you know what acidic substances and alkaline substances are? In order to understand this problem, I read a lot of books and looked up some information from the internet. If you don't understand, come and do the experiment with me! We need to use a substance called purple litmus test solution. If not, we can add some hot water to the purple cabbage, soak it for ten minutes and then take it out. The same is true for experiments with purple water. We take a little white vinegar from home and add a few drops of purple "water", which will turn red, indicating that white vinegar is an acidic substance; Adding baking soda to purple "water" will turn blue, indicating that baking soda is an alkaline substance.

I also did the same experiment on washing powder, soap, lemon juice, watermelon juice and egg white. It is really interesting! Try it if you don't believe me!

This is the mystery of science!

Today, the teacher gave us an assignment: discovering scientific phenomena around us. The word science in my mind always gives me a feeling that it is far away from us. Only when a spaceship goes into the sky and a submarine goes into the sea can it be called science. I really don't know where to start if I want to discover the scientific phenomena around me.

When I got home, I thought sadly: What scientific phenomena are there around me? Looking at me in a daze, my mother asked me, "What's the matter? Today is so abnormal that I won't say a word when I come back. " I told my mother my doubts, and my mother smiled and said, "Isn't it easy?" Scientific phenomena are everywhere. "When my mother saw that I still didn't believe it, she said to me," Take simple dish washing as an example. A bowl with detergent is easier to clean. This is a scientific phenomenon. "I was dubious at the time and suddenly thought that I could check it online. I quickly turned on the computer. After careful examination, I finally understand that the surfactant contained in the detergent can emulsify the oil stain and disperse it in the aqueous solution in the form of emulsion to remove the oil stain on the surface of the porcelain plate.

I see, it suddenly dawned on me, especially when I didn't expect this kind of housework to have a scientific phenomenon. It seems that there is no difference between big science and small science. It exists in every corner of our life and makes our life better.

Plug in the wings of science and release the theme. This afternoon, I studied Little Newton Science in Hong Wen Summer School.

Little Newton's science class is in Room 204 on the second floor. When I came to the classroom, I was the second in my class, and it was only 10 minutes before class time. Many students didn't come. They came very late. After a while, two students from our class came in. They are Ji and Wen Wanrou. I will play with them as soon as they arrive.

When the bell rang, the teacher came in and said, "Little Newton made a mechanical activity diagram scientifically today." As soon as the teacher's voice fell, a classmate asked, "What is a mechanical animation?" . The teacher said, "This is a touching picture". The teacher explained the method in detail, and we started to do it: Step 1, stick glue, stick two pieces of double-sided adhesive on the joystick and the four-headed connecting rod respectively and fold them. Step 2, fix the joystick on two cards respectively, and fix the four connecting rods on the joystick in turn. The last step is to paste people. People and animals will be pasted on the corresponding pictures respectively, and the moving picture will be done.

The mechanical activity diagram is very flexible and can be given to your partner as a gift. Gently pull the transmission rod, and the villain can do the same or opposite action. The animation I made is very realistic. Teachers and classmates praised me for my exquisiteness. I am very happy. Today's class is really meaningful!

Plug in the wings of science and release the theme. I have a book that teaches how to do experiments. Idle, I turned over a few pages with great interest. Suddenly, I was attracted by a sentence-put the balloon on with steel wire, but it won't break, like a beautiful string of Sugar-Coated Berry. Give it a try! Seeing that the materials are simple and available at home, I decided to do this experiment.

According to the description in the article, this experiment needs: a steel wire, several balloons, a piece of sandpaper and lubricating oil. So I found sandpaper and lubricating oil at home. There are still wires and balloons missing, so I looked everywhere, but I still couldn't find them. I had to ask my father to go shopping with me, and then I got all the materials ready.

I first sharpen one end of the steel wire with sandpaper, and then apply lubricating oil. Then I blew some balloons and sealed the hole. Use a steel wire to go in from the top of the balloon and then come out from the end of the balloon. When I put it on, I found that the balloon didn't burst or leak. Next, I put on the remaining balloons one by one, which really looked like a string of Sugar-Coated Berry. I tried to puncture it from the side, but the balloon burst.

After checking the data, we know that the pressure on the side of the balloon is the greatest after it is blown up, and the pressure on the upper and lower ends is smaller. Therefore, after the steel wire is slowly inserted from the upper end of the balloon, the surface of the balloon will not suddenly break, but will be stuck. In this way, the air inside and outside the balloon does not flow, the atmospheric pressure is still in equilibrium, and the balloon will not rupture.

Even a small balloon has such a great mystery. As long as we pay attention, we will find that science is everywhere in our lives.

Plug in the wings of science and fly excellent composition theme 7 The Science and Technology Festival of our school has opened again! The project of this science and technology festival competition is "Water Building". Today, Teacher Yang solemnly said to everyone, "In this class, we will select contestants. You go to pour water in groups and prepare paper cups on the table. "

The game has started. According to teacher Yang's request, I first put the bottom six paper cups on the washbasin. At this time, I found the cup floating on the water, always swinging from side to side. Is there any good way to keep the cup from shaking? Suddenly, I saw my classmate pour water into six cups. Soon, a miracle happened in the cup! I saw the glass standing steadily. I quickly followed his example and poured some water into the cup so that my cup wouldn't shake. Then, I stacked the cups layer by layer. Just when I was proud, I heard a bang and all the cups fell. I failed, very disappointed! At this time, the teacher gave the order to "stop" and all the students stopped. Then the teacher announced to us the contestants who participated in the "Water Building" this time.

"Water architecture" not only exercised our children's practical ability, but also tapped our wisdom! Even added infinite fun to our after-school life. We are gradually moving towards the door of science, and hope that next year's science and technology festival will be more exciting!
