In our daily study, work and life, we often come into contact with composition, which is generally needed for an activity and an essay contest. After the author submits the manuscript to the organizer of the essay activity, the author's work can participate in the competition, but part of the copyright is also given to the organizer of the essay activity accordingly. I believe many friends are very upset about writing a composition. The following is my essay on popular science of smart life, which is for reference only. Welcome to reading.
Essay on Intelligent Life Science 1 Life is full of science; Science, full of life. Solve problems in life with science, make life better and make life smarter.
That day, I went shopping, took a fancy to a wishing bottle, bought it and arranged it in the corner of my desk. I always feel that something is unreasonable. A closer look reveals that the original label covers a corner of the pattern. This is like a black spot in white, losing elegance and sweeping away interest. I quickly tried to take off the label.
I carefully tore off a corner of the label and touched the tear with my hand. Sticky and uncomfortable. I scratched it again with a colorless pen tip, and it was still the same. Helpless, in order to protect the feel of wishing star, I had to give up. It's no good tearing. I have to think of another way. Rinse the label with water, but it will get wet. No If you rub it with your hand, the label will get dirty. No It doesn't work with a sharp blade ... all kinds of amazing methods have been tried, but the label just doesn't fall off like it grows on it.
When I am depressed, I pat my head and think of what I can't find in this technologically advanced era. So, I turned on the computer and asked "what do you think". Soon, I got a specious answer: blow (hot air) with a hair dryer. Because the hot air blows hard on the sticker behind the label, it loses its stickiness and becomes a "vase". The label doesn't stick to the bottle and naturally falls off. "Seeing is believing", I quickly went to the bathroom to get a hair dryer, drove it to the hot air booth and blew it at the label. Gradually, the label seems to have moved and it feels a lot looser. I quickly put down the hair dryer, picked up the bottle and gently tore it. The label came out of the bottle like an obedient baby.
In life, we often encounter some thorny problems. Let's use our brains and try our best. And if we can face it with a scientific attitude, I believe these problems will be solved soon. Let's act, let wisdom fill life, let laughter fill life!
Intelligent life science essay 2 ink is used for writing. However, it is difficult to eliminate ordinary ink after writing, which hinders the recycling of paper. I saw a magic ink in the column "I love inventing" today.
According to Professor Dong Chuan, the inventor of this ink, "The magic of this ink is that it will disappear under the action of light and water after writing. Therefore, we named this ink' Fashion Ink'. " The reporter is a little incredulous and is going to do an experiment to verify Professor Dong's ink.
The reporter prepared three kinds of paper: printing paper, writing paper and newspaper. First of all, the reporter wrote and painted on the printing paper with easy-to-fade ink, ordinary watercolor pen and watercolor pigment, and then sprayed water on it with a flower watering nozzle. In less than a minute, you can clearly see that the words written in fadeable ink have changed obviously and the color has faded a lot, but it will take some time to disappear. Then, the reporter wrote on stationery and newspapers. However, what was written on the stationery did not disappear. Professor Dong explained: "Because the fibers used to make all kinds of paper are different, and the penetration degree of this ink is different from that of all kinds of paper, the fibers and ink of stationery like this have strong penetration, so it takes a long time." Then I read the newspaper, and the result was greatly unexpected. The words in the newspaper disappeared as soon as they touched the water. Looking at the three pieces of paper together, the words written by Professor Dong in ink are almost invisible, but there are still some traces.
To this end, Professor Dong invented another kind of paper. In fact, this kind of paper is nothing special, just covering ordinary paper with a plastic film. Write on it with faded ink. Wipe it with a wet cloth, and there is no trace at all. Wipe it gently and the trace on the cloth will be gone.
Although this kind of ink can improve the utilization rate of waste paper, it will disappear when it touches water. If it is a roll paper for examination, it will be bad. In order to perfect this kind of ink, Professor Dong invented another kind of ink which can be dissolved in boiling water. Later, the reporter started the experiment again.
There are two pots heating on the table. After the water boiled, the reporter put the ordinary printed printing paper in one pot and the paper with ink invented by Professor Dong in another pot. The water temperature rises slowly. When the water temperature reaches 50℃, you can see that the ink characters have disappeared, the water has not changed, and the ordinary printing paper has not changed.
It's amazing! I hope this kind of ink can be widely used in our daily life in the future, which will greatly reduce the waste of paper.
Intelligent Life Science Essay 3 Dust is something that everyone hates. The harm of dust and bacteria is one of the intolerable phenomena of human beings. Dust is concrete and sometimes abstract. It is ubiquitous, difficult to prevent, and breeds harmful particles ... dust flies everywhere, carrying many bacteria, viruses and eggs, spreading diseases. Industrial dust and fiber dust can make workers suffer from various incurable occupational diseases. Excessive dust will also cause environmental pollution, affect people's normal life and work, and induce human respiratory diseases. ...
From the physical characteristics of dust, dust is a kind of solid impurity with irregular shape, mostly angular and with gray, brown, black and other colors, with water absorption. When there is a lot of dust in the air and the relative humidity reaches a certain level, water vapor forms water droplets, so the dust is easily wetted by water and easily absorbs water.
Looking at its chemical characteristics, the composition of dust is more complicated, and sometimes it provides acid radicals and metal ions that lead to degradation. Some dust itself is acidic or alkaline, such as sulfuric acid smog, photochemical smog, metal oxides and other particles are alkaline. In addition, the floating dust in the dust is acidic or alkaline because of its small particle size, small surface area and strong adsorption capacity. Dust often contains substances such as clay, which will absorb moisture in the air or substances composed of archives, make it undergo hydrolysis reaction and decompose viscous aluminum hydroxide.
Biological characteristics: Because the spores of mold are small and heavy, they are scattered around with the air and inevitably attached to dust, so dust is an ideal culture medium, breeding ground and disseminator for microorganisms. Microorganisms secrete mildew spots containing enzymes and organic acids during their growth. Dust is annoying to everyone, and it is harmful to the environment? Health is harmful to human health. Therefore, throughout the ages, people have always been "diligent, not dusty." However, have you ever thought that human beings can't live without dust? If there is really no dust in nature, what kind of situation will we face?
The diameter of dust particles is generally between one ten thousandth and one millionth of a millimeter. The dust that the human eye can see is a giant in the dust, and the tiny dust can only be seen under a high-power microscope. The main sources of dust are soil and rocks. After weathering, they split into fine particles. These particles float in the air with other organic particles. They absorb some sunlight and reflect it around, just like countless point light sources. The sunlight is greatly weakened by the reflection of dust, so it becomes soft. If there is no dust in the atmosphere, strong sunlight will make people unable to open their eyes.
Interestingly, dust particles also have a "strange temper", which tends to reflect purple, blue and cyan light with shorter wavelengths, and "likes" to absorb other colors with longer wavelengths. The sky we see on the ground is blue because of the high dust content in the lower atmosphere. If there were no dust in the atmosphere, the sky would be white.
Most dust is hygroscopic. Water vapor in the air must adhere to dust to condense into small water droplets. In this way, when the water vapor in the air reaches saturation, the dispersed water vapor will adhere? Dust forms stable water droplets that can float in the air for a long time. If there is no dust in the air, everything on the ground will be wet. What's more, there can be no clouds in the sky, and it is impossible to form rain and snow to adjust the climate, so it is impossible for water evaporated from the ground to return to the ground. If there is less and less water on the earth and it dries up completely, living things can't survive. In addition, due to the refraction of sunlight by these water droplets, there will be colorful natural scenery such as sunset glow, idle clouds and rainbow halo from Zhao Hui. If there were no dust in the air, how monotonous nature would be!
The role of dust tells us that everything has its two sides, even some things that people regard as "waste" often have its existence value that cannot be ignored. Only by correctly understanding them can we seek advantages and avoid disadvantages and benefit mankind.

The trees on both sides of the artificial lake in Jiulong River are lush, the river is so green, and the blue sky, white clouds, houses and green trees are reflected on the river like a beautiful picture. The beautiful Hua 'an is permeated with a harmonious atmosphere everywhere.
In the community.
The grass in the community is green and the unknown flowers are beautiful and clean. Children go to school happily in groups of three and five with schoolbags on their backs; After school, I would hum a song or talk and laugh and skip home like a rabbit. After the children finish their homework, they get together to play hide-and-seek, ride bicycles, play football and other games. My brothers and sisters sometimes invite us to skate, skateboard and watch colorful lanterns to form a colorful dragon. Let's laugh and cheer, not to mention how happy we are!
Next to the waiting station
Everyone waited patiently for the arrival of the bus, but the fierce sunshine left sweat on people's faces. Finally, the car stopped and everyone crowded in the direction where it stopped. 1 of "brush", the door opened and people got on in turn. Hot weather is inevitably annoying, but no one cuts in line or pushes me. When I got on the bus, there were no seats left. At this time, a little brother warmly greeted: "Brother, come and sit with me!" " "My little brother and I smiled at one another and crowded together. The car went on. After a while, another grandmother came up and several young people offered their seats. Grandma's face is filled with a gratified smile. What a beautiful and harmonious picture this is.
Artificial lakeside
As night falls and the lights are on, the Jiulong River becomes a sea of lights, which is even more beautiful. Trees on both sides put on bright new clothes, strings of colorful lanterns are confusing, and neon lights on high buildings are flashing, reflecting on the lake like stars all over the sky. The new bridge built on the artificial lake, like a rainbow, connects the north and south banks, adding a lot of charm to the artificial lake. When people are full, they come to the lake for a walk, either scurrying or walking slowly. It's so cozy, and the cool breeze gently caresses their faces, which makes people feel refreshed. Tired of walking, you can take a nap on the bench on the shore and enjoy the peace of the night. Young parents are holding their toddlers with smiles on their faces. Look at the pavilion by the lake. Old people in twos and threes are laughing and recalling the past. Hearing their hearty laughter, it seems to be back to youth. How happy this scene is.
A harmonious home is beautiful, civilized and warm. I love my home.
Everyone will not be unfamiliar with 6 essays on smart life science. They are like a pair of wings, helping birds fly. Our study and life can't be separated from them ... Some students don't like reading and feel bored. Actually, it's not like this. Books will bring us a lot of fun, happiness and knowledge. If you are willing to sit down and read a book, you will feel that all the fun and knowledge in the book will be reflected in front of your eyes.
Some scientific and technological issues closely related to the daily life of ordinary people, such as energy conservation and environmental protection, food safety, disaster reduction and prevention, climate change, scientific fitness, intellectual property rights, etc. The large-scale popular science map of smart life provided by Zhongshan Science and Technology Museum introduces how to save water, oil, electricity and paper in life, infiltrate the awareness of saving and advocate a low-carbon life through the introduction of life tips. The prize-winning popular science knowledge question-and-answer activity focuses on promoting scientific treatment of three wastes and environmental protection.
Einstein once said: Wisdom without books is like a bird with broken wings. The book not only gave me pleasure, but also supplemented my spiritual emptiness. I hunted everything in the book like a hungry wolf. Books are my soul. Reading brings me infinite happiness. Once, I squatted in the corner to watch ants. Ants are struggling to climb a low wall. Maybe it's because the walls are very rough. Every time it climbs halfway, it will fall. Later, I gradually groped for higher and higher, but I never reached the top. I was impatient with it, so I turned to observe other ants. After a while, I was about to get up and leave, but I was surprised to find that ants were lying on the wall relaxing their tentacles. From then on, I understood the meaning of "perseverance can succeed" and the truth of "the iron pestle is ground into a needle".
Wisdom is the seed that allows you to harvest the granary: wisdom is the breeze that allows you to ride the wind and waves; Wisdom is a clear spring that allows you to embrace the ocean; Wisdom is a ray of sunshine, it can have the sun. My life is also wonderful because of wisdom. Let's grow up in the book!
What is wisdom and what is life? Will understanding differences directly affect a person's life? I thought the same thing.
Whether life is wise or not, no matter what "state" life is in, the decisive factor lies in what "state of mind" life is in. For people who lack material resources, they need to learn to be confident, dedicated and positive. For people who are rich in material things, they need to learn to be surplus without being fascinated, and learn to be modest, sincere and calm. Different "states" are actually the results of different "moods", one of which is self-confidence and compassion. This mentality can accommodate all positive and negative energy events without being affected by them, and this mentality is very confident in grasping the presentation and creation law of "state". We don't lack wisdom, we just misunderstand.
Every moment of our existence is worthy of gratitude. We are presented in the whole physical universe in a "perfect way", which is mixed with the whole cosmic energy. Every existence is a perfect representation of the universe. Most importantly, we are actually creative. Through our imagination and action, the results will be presented. Gratitude, at the same time, is also a strong and low-key self-confidence, which can achieve our dreams. I don't think there is anything more colorful than "living in a dream creative life".
Life, or it can be a work of wisdom.
We are not only physical beings, but also conscious and energetic beings in the universe. Humans have been arguing about this, but this is the essence. The difference between an argument and its essence is that the argument is inferential, provable, descriptive, recordable and measurable, and the essence needs to be felt and understood by one's own heart. We can't find the perfect in this universe, because all beings are perfectly unified. If we regain our confidence and wisdom in life, our overall social environment will present a "beautiful home" corresponding to human politeness.
I think life is perfect. No matter what "state" it is, it just reflects our "mentality".
The 8-hop pot cover of the smart life science essay has brought the steam power era to the world, and the apples falling from the trees have pushed modern physics to a new height. Life inspires skilled craftsmen and wise sages, and gives them the power to shake the world.
Life is fair, and he gave me wisdom. If I were a clear canal, life would be a clear spring, injecting living water of wisdom into my veins; If I were a green tree, life would be soil, and the minerals of wisdom would be sent to my roots. If I bend a Hongqiao, life is sunshine, painted with wisdom pigments. The life wisdom I have learned can't change the world, but it is enough to improve myself.
When I was a child, I liked to squat in the corner and watch ants. At first, I was just curious. Later, as I grew older, I gradually understood something. Once, I saw an ant struggling to climb a low wall, probably because the wall was too smooth. Every time it climbs nearly halfway, it will slide down, and then it will gradually climb higher and higher, but it never reaches the top. I was impatient, so I turned to observe other ants. After a while, I was about to get up and leave, but I was surprised to find that ants were lying on the wall relaxing their tentacles.
From then on, I understood the meaning of "perseverance can succeed" and the truth that my mother said "the iron pestle is ground into a needle" Therefore, over the years, I have never been overwhelmed by difficulties, but I have a firm goal and never give up.
Life not only taught me firmness in adversity, but also taught me calmness in prosperity. It is often said that "boiling water does not ring, but ringing water does not boil". To confirm this statement, I have been staring at the kettle by the fire. When the pot began to stir, it made a crackling sound, which became louder and louder, giving people a sense of fragmentation. Later, the agitation gradually subsided, leaving only a lingering sound, as if it were a poet's whistle. Then, I understand that a truly talented person will not be sharp-edged and grandstanding, as the saying goes, "big talk is rare, elephants are rare."
Life has given me the wisdom to be a man, and it has also given me the wisdom to deal with people. Looking at the flowers in the field, I found that a rose was extremely beautiful, and I couldn't help but have the idea of picking it. But I just reached out and shrank back because of a sharp pain-I ignored the sharp thorns on the stem, so I realized that everyone, like a rose, has something you appreciate and something you can't tolerate. When interacting with people, you should not only avoid being stabbed, but also prevent stabbing people you cherish.
Life is like a calm philosopher. It writes wisdom into my daily life, teaches me correct behavior and leads me to a brilliant tomorrow.
On a Sunday in mid-August, after the continuous drizzle moistened everything, the sun smiled again, birds sang happily, and plants dripped dew, as if praising the drizzle. Chinese rose flowers on both sides of the road, red flowers stand upright on green branches and leaves, and the sun is floating on colorful flowers. On such a beautiful day, my mother and I visited the China Science and Technology Museum.
China Science and Technology Museum is located in Beijing North Third Ring Road. It is made of red bricks and has three floors. There is also a silver circular building next to the China Science and Technology Museum, which is the famous "Variable Screen Cinema".
My mother and I first came to the "experimental field" on the second floor. At this time, the experiment has just begun, only to see the instructor aunt take out an alloy bud and take out a hair dryer to heat the bud, only to see the bud slowly blooming. Turn off the hair dryer. When the temperature drops, the blooming buds gradually close again. The commentator's aunt said that this phenomenon is called two-way memory.
The commentator's aunt picked up a spring made of another alloy material. A fluffy duckling is tied to one end of the spring. She asked a child to hold a fluffy duck, and then heated the spring, which gradually straightened and became a straight wire. When the temperature drops, the spring is still straight and cannot return to its original position. Only by heating again can the spring shrink back to its original position bit by bit. This phenomenon is called one-way memory.
After explanation, I know that this material is very useful, for example, it is often used in hotel fireworks alarm devices. The third experiment is "faraday cage". There is a big iron cage with insulation board, on which people can stand and be isolated from the ground. Aunt commentator invited two uncles into the cage and closed the door. At this time, she pressed the power switch and the cage was charged. She told everyone that the voltage of the cage was 50,000 volts at this time. Wow! People are worried about people in cages, but people in cages are not in danger. They even dare to touch the cage with their hands Dare outsiders touch the cage? The narrator's aunt said she didn't dare to take the risk. She brought a long pole with a piece of wire at the top. She touched the cage with the top of the pole and only saw a blue electric spark and a click. It's really scary Why? The commentator's aunt told us: This is because the people in the cage are standing on the insulation board, and the voltage at any part of them is 50,000 volts. The voltage in the cage is 50,000 volts, and the voltage is zero. People outside are standing on the ground, and the ground voltage is zero. The voltage of the cage is 50 thousand volts, so people outside must never touch the cage. This experiment also told me a truth-children are not easy to move electricity, because their eyes are invisible without electricity.
After watching the experimental performance, I watched Wonderful Water Drops, Submarines, Soap Chips, Photo Wall and Are You or Me, which made me learn a lot of scientific knowledge.
China Science and Technology Museum, you are like a book, let people learn scientific knowledge; You are like a huge picture, showing people today's science. I praise you-China Science and Technology Museum!
