Science is everywhere. It exists in every detail of your life. Therefore, a person's life is inseparable from science.

Science is around me, and I want to observe it carefully. You can't eat fruit while eating, and you can't eat fruit after eating. Why is this? This is a learning in life. If you eat fruit while eating, there will be a substance in the fruit that will affect the digestion of the stomach. If you eat like this for a long time, it is equivalent to taking chronic poison for a long time. Once the stomach acid is too much, it will cause stomach trouble! Such a small diet can make people get stomach trouble. It is conceivable that many details and habits around you are unsafe and unsanitary. Pediatrics tells you to be careful with every little detail.

There are many sciences around us. A teacup, a book, a pencil case, a pen, a window, etc. are all the crystallization of human wisdom. They discovered science and made us little by little. In addition, some sciences are dangerous in life, but they are also very useful as long as people understand and treat them correctly.

In a room, open the window and keep it ventilated, otherwise the indoor air will become dull and make people feel groggy. Isn't it better to open the window and breathe fresh air every day than to feel dizzy every day? Even if you don't open the window, this person must be too lazy or have super amnesia, which further shows that if you don't carefully observe virology in life, you will easily die of these inconspicuous details. Science is all around us, and dangers coexist. Only those who respect the science around them can stay away from him. At home, it is a safe place and a very dangerous place. Some people like to grow flowers, so they put them in the bedroom, but you never thought that some flowers would be harmful to their health. The fragrance of Chinese rose flowers will make people suddenly feel chest tightness and discomfort, hold their breath and have difficulty breathing after smelling it; Rhododendron is beautiful, but it has poison. The plants and flowers of yellow rhododendron contain toxins, which will be poisoned when people touch them. Rhododendrons of all colors have different toxins. This kind of flower must not be kept in the bedroom, it is life-threatening!

A flower and a habit are closely related to science and our health and life. Science is everywhere. Let's all care about science, understand science, respect science and make our life better! Our motherland is richer and stronger! Our world is more wonderful!

As time goes by, technology has been widely used around us.

It is like a ray of warm sunshine, illuminating our road to prosperity; It is like a colorful rainbow, holding up the hope of the motherland tomorrow; It is like a gratifying spring rain, nourishing our long-awaited labor-saving and convenient heart.

In old China, where science and technology were backward, many problems brought inconvenience to people.

When Qin Shihuang built the Great Wall in Wan Li, he spent a lot of manpower and material resources. It is said that the Great Wall of Wan Li is made of bones.

In ancient times, there were no fast means of transportation. People use people's feet to transport letters, and it takes about three months to receive them.

Instead of making a phone call and sending an email as it is now, it will be received immediately.

Time flies, the sun and the moon fly like a shuttle.

Now, in this era covered by technology, people can see technology everywhere.

The TV set at home can understand state affairs and relax; The refrigerator at home can store food so as not to rot; The washing machine at home can wash clothes quickly without hand rubbing; The computer at home can also check information online, chat with friends and so on.

Out of the house, cars, vans and trucks are running on the wide road.

Overpasses crisscross, dazzling.

High-rise buildings, like towering peaks, make people shine.

Walking into the beautiful campus, the tall teaching building stands in the center of the campus, all because of technology.

The classroom uses multimedia and bright lights, and the security door always guards the safety of the classroom.

2 1 century, wherever we go, technology is around us, relieving our fatigue and bringing convenience.

It can be said that technology is everywhere.

Looking at this era surrounded by high technology, all this is the crystallization of the wisdom of the working people, the eternal pride of the people of China, and the only way for China to prosper.

Technology is with me! ...

Science is by my side. Science is by my side. One day, it was very hot. Just about to go home, I found a puppy blinded by the sun, so I closed my eyes and left, but it was a path ahead, but it hit a tree.

I was curious, so I walked home quickly.

Walking to the door, I stopped.

I thought: dogs are not as smart as people, so I shouldn't hit the door! So I walked with my eyes closed and bumped into the door.

I was hit hard and a little dizzy, so I opened the door and hurried home.

When I got home, I immediately turned on my computer and searched on "Soso": People close their eyes ... Before I finished typing, a line came out: "Why do people walk to the left with their eyes closed?" I clicked in and saw the standard answer: this is the left-leaning phenomenon of the human body.

Because the human body usually exerts its strength on the right side, such as writing with the right hand and walking with the right leg first ... Physiologically, the muscles on the right side are more developed than those on the left.

Because people can see the road ahead clearly, eyes and brain can make adjustments in time.

If there is no control of the eyes and nerves, the control of the human brain will lose its function, and people will unconsciously let their feet betray, so there is a phenomenon of left leaning.

So, I tape the right wheel of a car, push it forward, and it will turn left.

Through this experiment, I found that science is everywhere. As long as you observe carefully, you will gain a lot.

In order to acquire more knowledge, we must always observe the scientific phenomena around us.

Technology is around me. Technology is around me. It will not be carved on rocks, nor will it float in the vast blue sky, nor will it be in the boundless sea.

It is around us, as long as we observe it carefully and explore its mystery, you can find it! Technology is everywhere and needs our careful observation.

For example, in the past, people used to use carriages or walk, which took a long time to get there and was very troublesome. Now, it is much easier to go there by car or plane. In the past, during the Spring Festival, the cold weather restricted people's activities and reduced a lot of excitement. Now, technology has brought us air conditioning and electric heating, which has made people's lives much more convenient. In the past, people worked hard at home all day and didn't know what was new in the world. With TV, radio and Internet, we can learn about state affairs without going out. As a famous saying goes, "A scholar can know what is happening in the world without going out" ... At the same time, I discovered the technologies developed by China through various channels, such as the first successful launch in 2003. In 2005, "Shenzhou VI" once again witnessed the maturity of China's space technology, laying a solid foundation for the "Shenzhou VII" spacewalk; In 2008, "Shenzhou VII" successfully completed the spacewalk mission; 20 12 "Shenzhou IX" docked with Tiangong 1 in space ... With the development of science step by step, let's cheer for China again and again and shout for the motherland! But I don't think these are enough. There are still some problems in life, so I want to invent something.

For example, walk into a department store, pull out one of the neat shopping carts in order and get on the elevator.

Why is the shopping cart stuck in the elevator? The "four feet" seem to be glued to the elevator with super glue.

At the elevator exit, the shopping cart easily "got off" the elevator.

What's going on here? It turns out that all four wheels of the shopping cart are equipped with electromagnets, which can "suck" together with the elevator.

This avoids a lot of trouble on the elevator.

When I walked to the second floor of shopping, I found that the counter where I used to store parcels disappeared and was replaced by a small blue cabinet.

As long as you press the "Save" button in the keyboard area of the cabinet, it will spit out a white note from its mouth with the number of the cabinet you own written on it, and that cabinet will automatically open at this time.

You put the things you need to store in the cupboard, and then cover the cupboard door.

Similarly, when taking something: press the "take" key in the keyboard area first, then take out your note and show it to the "eyes" of the cabinet. After the cabinet confirms that you are the owner of a cabinet, it will open your corresponding cabinet.

And ... I believe that our science and technology will continue to progress and develop in the future! launch ...

I let the eggs float. In science class today, we did an interesting experiment-let the eggs float.

As soon as I got home, I excitedly said to everyone, "I can make eggs float in the water." Do you believe it? " Everyone looked at me with suspicion.

Dad smiled and said, "When did our Mona learn to brag?" I solemnly said: "This is not bragging, this is science! If you don't believe me, let the facts speak for themselves.

"Say that finish, I went into the kitchen.

I first took out a small basin, received some clear water, then poured a lot of salt into it, and then stirred it hard, and soon the salt dissolved in the water.

I took out an egg and gently put it into the water, but the egg swayed on the water a few times and then slowly sank.

I see. The teacher said that eggs can only float if the salt concentration is high enough.

So I poured a bag of salt into it, stirred it to dissolve, and then I put the eggs into the water. Wow! Eggs really float on the water! I put it back a few times to make sure it doesn't sink, and then I took the small pot out.

I said loudly to everyone: "Come and see my magical scientific experiment-let the eggs float!" " "I put the egg on the water and saw that it really floated on the water. The eyes of the whole family are full of surprise and incomprehension.

Mother also curiously pressed the egg down with her hand, but as soon as her hand was loose, the egg bounced again.

My mother said excitedly, "It's strange, it's the first time I've seen it.

"Say that finish and went into the kitchen to cook.

I proudly said to my father, "What happened? I'm not bragging, am I? " Dad nodded and said, "Not to brag, our Mona has become a little scientist? However, can you tell me the truth? " "In fact, this truth is very simple.

"I bob," this is because after adding salt to the water, the density of salt water will increase. With the increase of salt in water, the buoyancy of salt water will become larger and larger. When the buoyancy is greater than the weight of the egg, the egg will float.

This is the same reason that the Dead Sea can make people float. The salt content of the Dead Sea is very high, which is said to be ten times that of the ordinary ocean, so it is easy for swimmers to float.

"Dad gave a thumbs-up and said," Well said, it's called knowing it but not knowing why.

This is the real little scientist! "I was enjoying my father's praise proudly when I suddenly heard my mother shouting in the kitchen," Where's the salt? Why is there no salt? Don't want to eat at noon? " Hearing this, my father immediately gave me a wink. Naturally, I got the message and hurried into my cabin.

I just heard my father say outside, "wait a minute, madam, I'll buy salt!" " "One day, I was playing in the living room. Suddenly, I heard my father talking to himself in the kitchen: "well, what can I do?" "I went in.

I saw my father holding his beloved tie in one hand and patting the back of his head in the other, with a sad face.

When I saw this scene, I smiled and asked, "What's the matter? Dad, do you have any problems? " "Alas," dad sighed, "I accidentally spilled peanut oil on my tie, which is my favorite!" I said, "That's not easy. Just wash it, don't say it. "

Dad gave me a white look and said, "This is a silk tie." Washing with water will deform.

"Suddenly, I remembered the ingenious method of washing silk I saw in the book.

So I said to my father, "Leave it to me. Don't worry, I'll wash it as good as new, but you have to invite me to McDonald's tomorrow. "

"Dad hesitated, but he could and did not think of any good way, so he gave me the tie with a grain of salt.

I walked into the bathroom with a tie. My father was very upset and wanted to follow me, but I turned him away.

I first took out a plastic jar, poured some glycerin into it, and then stuffed the tie in to cover the bottle mouth. I shook it hard.

Shake it for a long time and take out your tie. I looked at it carefully several times, and the oil stain really disappeared.

I wiped it with a dry towel again, then came out and handed it to my father proudly.

Dad took the tie and looked at it from top to bottom, from the back to the front. While watching it, he boasted, "It's so clean and really washed!" " Looking at it, I found that my father forgot what he promised me, so I reminded him, "Dad, don't just remember to look at your tie, but don't forget to go to McDonald's! "Dad pretended to be confused and asked," What McDonald's are you going to? "Did I say I was going?" When I heard this, my face turned red and I said angrily, "Dad cheated, Dad cheated!" " "Dad smiled and said," Ha ha, I'm kidding. Don't worry, I will definitely take you to McDonald's tomorrow! " "

Ask for a composition of about 450 words with the technology around me as the theme! Author: Look up the dictionary With the passage of time and the rapid development of the motherland, many things are developing rapidly, and our lives are getting richer and richer. However, if anything has changed our lives, I think it must be said that technology is always everywhere, and technology is by my side.

Walking on the road at night, there are electric lights to illuminate us; Call a friend and take out your mobile phone at your fingertips; Back home, turn on the TV to watch the news, turn on the computer and chat with friends; Mother steamed rice with a rice cooker; Turn on the electric heater; The whole family is sitting around, enjoying the delicious food prepared by my mother with an electric wok ... Do you think we can leave technology anytime and anywhere? Technology is very useful! For example, if there is no electric car, it will be inconvenient for us to communicate with distant relatives and friends; If there is no EMU, it will be difficult for people to travel everywhere. Without the space shuttle, it would be empty talk for people to go into space; If there were no icebreakers, it would be difficult for us to go to Antarctica. Without space instruments, it would be just an illusion for humans to land on the moon ... On the contrary, with technology, our life will be better-with fax, our documents can be easily transmitted instantly! With robots, you can be in a space that people can't reach; Using laser, you can make fitness equipment; With air conditioning, people can feel as comfortable as spring even in hot summer ... Technology not only makes our life better, but also marks the progress of our society. Technology is around me, so we should study harder and make our own contribution to the development of technology. ...

Science and technology are around me. 600 words science and technology are around me. Students mentioned "science and technology" in their compositions. Perhaps the first thing you think of is the cutting-edge technologies such as rocket ascending into the sky, submarine entering the water, suspended train, Shenzhou-8 and Tiangong-1.

In fact, technology is not far away from us: when the hot summer comes, we can enjoy the cool in a comfortable air-conditioned room; When we are hungry, my mother cooks a delicious meal for us with an induction cooker, a rice cooker and a microwave oven. When we are too busy studying or working to take care of a lot of clothes to change, the washing machine solves the problem for us … Look, technology is around us.

Going home from school on Friday, sitting in front of the TV, listening to pop songs and watching Chinese and foreign news anecdotes broadened my horizons, enriched my knowledge and made me happy. It's really "knowing what's going on in the world without leaving home."

When visiting relatives and friends, electric cars, motorcycles and even more and more popular cars have shown infinite charm. It won't be long before we can get together with our relatives and friends under the breeze.

When we go out to travel, or get on the train and fly in the mountains, we can see the beauty of nature at a glance; Or fly in the vast sky, accompanied by blue sky and white clouds; Even sitting on the maglev train, you can feel the comfort of lightning speed.

Technology is really amazing and brings people a lot of convenience.

The emergence of telephones and mobile phones has made us bid farewell to the era of flying pigeons delivering books and enhanced the communication between people.

The popularization and use of computers not only brings people a way to get rich, solves many problems in people's lives, but also eliminates the pain of missing distant relatives.

This summer vacation, my family bought a computer. Through the video, grandma met her father who worked in Guangzhou. This made grandma very happy, changed her old malaise, and she was happy all day, and never nagged her father to come back to chat with her again.

Even in our rural schools, computers and multimedia devices are used in classrooms, which greatly improves our interest in learning.

..... Watt invented the steam engine, Edison invented the incandescent lamp, Franklin invented the lightning rod, and Bell invented the telephone ... It was the development of science and technology that led the continuous progress of human society.

Our great ancestors, after numerous experiments, have created many miracles for us.

Nowadays, the development of science and technology is in full swing, and great achievements have been made in military, medical, aviation and daily life.

Cloning technology and nanotechnology are no longer strangers.

We live in the age of science and technology, and we grow up in the life of science and technology. As the founders of the new century, we should set up lofty aspirations and bravely climb the peak of science and technology.

Looking forward to the future, the motherland will be a great landscape, and in the near future, our life will be better by science and technology.

Technology is not only around me, but also in my heart, in my swaying dream.

launch ...

Technology is writing by my side. It takes 450 words to write 450 words. Technology is right beside me. With the change of time, the technology of 2 1 century is really more and more developed.

Let's see here first, whether computers, televisions, mobile phones and radios can reflect the development of science and technology.

If you can't feel it, don't worry.

Look over there with me. Cars, electronic dogs, automatic navigators, air conditioners, electric fans and many other items and technologies can reflect the increasingly developed science and technology in 2 1 century.

Technology is becoming more and more developed not only in daily life, but also in school.

See if the flexible wireless mouse can reflect the development of science and technology.

See if the projector hanging in the air can reflect the development of science and technology.

Do you think the big screen can reflect the development of science and technology? Let's see what the PE teacher is holding in the gym. Can Timer Reflect Technology?

You see, the rows of computers in the microcomputer classroom can reflect the development of science and technology.

There is no lack of beauty in the world, but the lack of eyes to find beauty.

As long as you pay attention to observation, you will find the development of science and technology in the world.

The scientific composition around me needs 600 words today. We are all teenagers. We have begun to study science, geography and biology, and we know a lot about science.

But have we ever paid attention to the science in life? I remember this summer vacation, my parents took me to Shanghai to broaden my horizons.

The car drove to the highway along the Yangtze River, and my parents and I had a good chat in the car.

Suddenly, there was a "rumbling" sound in my ear.

My heart is shaking, ah! What happened? Is there anything wrong with the engine? Or a car pulley? I almost feel the footsteps of "death" approaching.

I looked at my father and wondered: I was worried to death, but my father, the driver, was poised and completely carefree on his face.

When I was in a hurry, the noise disappeared, and I was secretly pleased at once, but before long, that terrible noise rang again and then disappeared … I was almost tortured to death by this repeated sound several times.

Finally, we came to the bustling metropolis-Shanghai.

I haven't heard such a sound for a long time before I asked my father doubtfully, "Why did I hear that terrible rumble on the road, but it disappeared after a while?" Dad laughed and said, "You little fool! Forget everything you have learned.

Do you remember the friction you learned in the fifth grade? If the friction is small, it will save labor; It will be very laborious if the friction is large.

On the expressway, some sections are asphalt roads, and some sections are cement roads, so the speed of the car is fast.

Therefore, when driving through the asphalt road, the friction is small and the sound is small; When driving through the cement road, the friction becomes larger and the sound becomes louder.

""Why can't you hear anything after the loud noise? " "That you don't know! This is called contrast. After hearing a loud noise, listen to a slight sound, and you won't feel other sounds. Now you know! Little fool ... "(I learned new knowledge by observing some phenomena in my life)! It turned out to be my psychological effect! What a false alarm.

However, from this incident, I also know that there are many scientific theories in our life, so we should dare to explore and explore! (Point out the center)

One morning, I was eating a delicious meal cooked by my mother with relish at home. I suddenly felt a little pain in my tooth, so I ignored it and continued to eat, but this tooth hurts like losing my temper with me.

I can't help but feel pain and tears.

My mother couldn't bear to see it, so she quickly took me to the hospital.

When I arrived at the dental clinic of the hospital, the doctor told my mother while checking: "I have tooth decay and need to be treated as soon as possible, otherwise the hole will be bigger and it will hurt if it is not blocked."

"The doctor for a while with a hook plug cotton, for a while with a dental drill" squeak "ring.

I was trembling with fear.

The doctor soon filled my teeth.

The doctor said to me, "little friend, do you know how your tooth decay came from?" Because you eat too many sweets.

"I don't understand:" How can I still have a toothache when I eat sweets? "The doctor said," there is a sticky thing in people's mouth called dental plaque. When it meets candy, snacks and snacks, it will produce acidic substances, which will specifically corrode teeth and become cavities.

Don't eat candy, eat less snacks, brush your teeth in the morning and evening, and rinse your mouth after meals.

"Mom said," what the doctor said is scientific.

Science is everywhere around us. Science is closely related to our life, and science is closely related to our health and life.

So we should talk about science in our life and remember what the doctor said.

Zww.cn Since then, I seldom eat sweets and insist on brushing my teeth.

No, I have a toothache.

I see: Science is very important to our health.
