It was raining lightly, and I came to the International Education Park, where a large-scale marine life science popularization exhibition was being held. First of all, what comes into view is a luxurious and modern urban architectural building. After walking through the door, we took the elevator to the marine life science popularization exhibition hall on the third floor.

As soon as you enter the museum, you will see large and small exhibition halls separated by wallpapers filled with marine science knowledge. There are fish of various colors and sizes in various forms of fish tanks. The most eye-catching thing is the introduction on the wallpaper. Carrying out popular science education is of great significance to our young students in protecting the ecological balance.

As you approach the fish tank, you will find all kinds of fish, including beautiful herringbone butterflies, strange dog-headed fish, and charming lucky cats. The most eye-catching thing is the ferocious alligator, which is lying there quietly, majestic, as if it is about to charge at any time; and the most peculiar thing is called the spiny puffer fish. I thought it was just a fish with long spines. , but when the stick touches it, it turns into a round ball, and each of its thorns stands upright. This should be its weapon to defend its opponents.

Among so many marine creatures, my favorite is the longevity star in the sea - sea turtles. Sea turtles are ancient and precious animals. They were born more than 200 million years ago and can live up to 152 years old. , a green sea turtle in this exhibition made me marvel. Its huge body weighs hundreds of kilograms. It is wearing armor and has four strong legs. It swims around as soon as it enters the water. It has a big head and a pair of It has round eyes that turn around from time to time. As long as there is a little movement, it will immediately put its head into the shell. It is really interesting and cute.

The marine life science exhibition enabled me to understand marine ecology and expand my horizons of the ocean. We must actively participate in marine ecological protection and make our sea more beautiful and magical. Excellent Science Popularization Essay 2

Today my mother and I came to Changshu Institute of Technology, because the high-tech giant simulated dynamic animal science exhibition is being held in the Pang Xun Art Museum of this university. My mother and I parked the car and went to the Pang Xun Art Museum. There were two big inflatable dinosaurs at the entrance of the Pang Xun Art Museum. The one on the left was thin and the one on the right was fat. They were so cute!

Mom took out her ticket and gave it to the ticket inspector, and then we ran in happily. As soon as we entered, we saw a lot of people surrounding something. I was tall. I was short, so I dug in. It took a lot of effort to get into the innermost layer of the crowd. I took a closer look and found that it was a Diplodocus that attracted so many people.

The Diplodocus was shaking its head and wagging its tail and roaring. Many children were teasing it with things. I laughed secretly in my heart: Oh, these are fake dinosaurs, and they have to feed it with things! We saw some dinosaurs elsewhere, such as Stegosaurus, Triceratops, Deinonychus, etc. Stegosaurus also moved its head and tail like Diplodocus. The more interesting thing is the Triceratops. I saw the Triceratops lying in a pile of sand. Its body swelled and shrank, and its eyes blinked, as if it was really alive and vivid. This is the simulated dinosaur behemoth exhibition area.

Then my mother and I came to the knowledge section exhibition area. There were quite a lot of people in the knowledge section, and many of them were writing something with pens. My mother and I walked over and took a look. It turned out that some people were answering the questions on the back of the tickets, and some were excerpting information.

The class bell rang, and the long-awaited comprehensive practical class began. In this class, our Moore team will teach you "Science Change". In order to leave a deep memory for everyone, we have been preparing for a long time.

First of all, we will introduce to you what science is and why we should study science. We have also collected stories about some well-known scientists such as Newton, Hawking, Einstein, and Qian Xuesen. With Ye Fengshuo's explanation, the exciting and interesting game began. The first game is "Magic Towel". Zhou Yan and I took two small towels, folded them into accordion-like folds after overlapping them, pinched them with our thumbs and index fingers, and asked the strongman Ye Fengshuo to pull them hard, but they couldn't be pulled apart.

The second game is "Coin Rooster Independent". Ma Qianjie put a thin note on the table, put a coin on it, and then slowly pulled the note away. This game is the most difficult. Ma Qianjie was both excited and nervous when performing. The whole class held their breath and watched nervously. When the banknotes were pulled into a straight line, the coin stood firmly on the banknotes, and the class suddenly burst into thunderous applause. The third game is "Straw Sprayer". Wang Yousheng poured a glass of water, put a long straw and a short straw at right angles into the water cup, and blew air from one end of the long straw, but there was no water mist. The host Ye Fengshuo couldn't wait any longer, so he rushed forward, took the long straw and blew on it. The water mist suddenly rose up from the short straw and sprayed all over my face. The whole class watched it and burst into laughter.

We performed the game, and Zhou Yan, Fang Lingchang, and Bao Zongzhe were not idle. They were busy explaining the principles. Ye Fengshuo's hosting was also wonderful, and everyone cooperated very well. Through the game, we learned about the principles of friction, center of gravity and air pressure. This event is so meaningful! Excellent Popular Science Composition 4

Our science experiment class today is really amazing. How amazing is it? Don’t worry, read on later!

What our Colorful Sunshine Holiday Team brings to you is the "Soy Sauce and Salt Water Duo". Add a few drops of soy sauce to a cup of tap water to make soy sauce water, then add some salt to the tap water to make concentrated salt water, and prepare a piece of paper. Our experimental tools are ready.

The experiment began. First cover the soy sauce cup with a piece of paper, then place the soy sauce cup upside down on the concentrated salt water cup, and then pull out the paper piece between the two water cups. You will find that the soy sauce water seeps down suddenly, and it is settled at It stopped moving, and the soy sauce water and concentrated salt water were clearly visible in black and white between the two water glasses.

How about the soy sauce water that is not mixed with concentrated salt water? Isn’t it amazing? Let me tell you the principle: It turns out that the density of concentrated salt water is greater and the density of soy sauce water is smaller, so the soy sauce water will float on the concentrated salt water. However, if you put concentrated salt water on top, the two glasses of water will mix with each other and become a light-colored mixed water.

Other teams brought "floating eggs", "unbreakable water bags", "unusual balloons", etc., all of which made people feel very magical and wonderful. !

This wonderful science experiment class ended with our applause and laughter, and we learned a lot of scientific principles from it. Science is wonderful, and there are many mysteries waiting for us to explore. We must put on the wings of science and fly to a perfect tomorrow! Excellent Popular Science Composition 5

"Whoosh, whoosh, whoosh" Hey, why is the playground so lively today? It turns out that this month is our school’s Science and Technology Festival, and we launched a unique science show.

There are rocket model launches, remote control four-wheel drive off-road vehicle models, remote control figure aircraft flight performances, remote control 3D stunt model aircraft, remote control electric motorcycles, remote control multi-copter aircraft and robots.

Among them, the one that amazed me the most was of course the remote-controlled electric motorcycle: after the rocket model was launched, a little man from Lilliput rode on his war horse---- The Lilliputian motorcycle was driving towards us. Liu Zimo beside me joked: "Hey! What's your name?" "Whoosh, whoosh!" It turned out that his name was Whoosh! At this time, the motorcycle had already driven to the other side of the playground. The children there stretched out their hands, wanting to run into the green space and catch him. The motorcycle drove faster and faster, and sometimes made several difficult moves. , even adults would make mistakes when doing these movements. Suddenly, this little man did a backflip, and our hearts were in our throats, for fear that he would fall, but in the end, he was safe and sound. In the end, He made a perfect drift, "Wow!" We marveled and gave a warm applause!

The performance is over, but our fun is still not over. The sun is slowly setting, as if it wants to linger on this beautiful time for a while longer. Excellent Popular Science Essay 6

Have you ever seen the mighty giant dinosaur, the huge luminous pearl and the magical dinosaur egg? Today I will take you to Pinghu Museum to feast your eyes on it!

Our earth was born more than 4 billion years ago! So how were humans born? Let me tell you!

The earliest era is the geological era, which is the era of geological division. Then came the Archaean Era, which was the early stage of the earth's formation.

Then came the age of bacteria and algae, which is the Proterozoic Era. After the Proterozoic Era came the Sinian Era, the age of bathing and nudity.

The following is the Cambrian period, which is the explosion of life as we all know it. Then came the Ordovician, a period when parrots were dominant. Then came the period of biological landing - the Silurian Period. This was followed closely by the Devonian Period, the famous fish period. After the Devonian Period came the Carboniferous Period, when insects entered the world.

Then came the Permian, the flourishing era of amphibians. After the Permian period came the Triassic period, when dinosaurs began to appear. The following is the Jurassic period that students are most familiar with, which is the heyday of dinosaurs. Gradually, the dinosaurs went from prosperity to extinction. This was the meteorite world - the Cretaceous period, and finally the dinosaurs became extinct. The Tertiary Period was the age of angiosperms and animals, and apes also began to appear. Finally, there is the Quaternary Age, the era of mankind.

This is the history of our great earth. Excellent Science Popularization Essay 7

Today, I actively participated in Dapuwan community activities - the popular science knowledge quiz competition.

I came to the conference room on the third floor of the community early. As soon as I got there, "Wow! It's so cool!" I couldn't help but scream. It turned out that the aunties in the community had prepared a comfortable environment for us. The brothers and sisters of Zhejiang Ocean University have also placed exquisite prizes on the podium.

At 9 o'clock sharp, the event started on time. The big brother first explained the rules of the competition: Whoever raises their hands the fastest will participate in answering the questions. If the answer is wrong, you will get one candy, and if you answer the question correctly, you will get two. In the end, whoever has the most candy will win the prize. The competition started. When my brother finished reading the first question, I immediately raised my hand, but I was still a little slow and a senior brother got it. But he answered wrongly, and we had a chance. This time I seized the opportunity, answered the question correctly and won 2 candies. In the next questions, I became more and more courageous. I was almost always the first to raise my hand to answer the questions. The other students were very angry. Why did I answer the questions? I looked at their unhappy expressions and thought: The important thing is to participate in such an activity, and it should also be given to other students so that they have the opportunity to answer questions. So, I reduced the number of times I raised my hands. As the event came to an end, I actively raised my hand again in order to get the prize. I got the right to answer the last question again and got it right. I was so happy because I was the first to answer the first question correctly, and I also finished the last question. I was so lucky, and finally entered the top three and won the prize.

Today’s activity was really meaningful. It taught me a lot. Not only did I increase my science knowledge, but I also understood that I need to be humble and agreeable to others, so that I can be happy for others and myself. Excellent Science Popularization Essay 8

This summer vacation, I had a rich and meaningful life, especially participating in the science popularization competition on behalf of our community, which left me with unforgettable memories.

Walking into the arena, it was tense and orderly. The host announced the start of the competition. Today's competition program is divided into three parts, including quick-answer questions, required-answer questions, and answering questions by watching videos. I was a little confused by this tense atmosphere. Monk Zhang Er was confused. As a result, after the first round, I only stuttered and answered two questions and did not get good results. I really regretted it. I hated it and vowed to get it back in the second round, so I gave full play to my advantages in the second part of the required questions, one after another, and solved them without any ambiguity. Finally, I handed in the answer sheet quickly and well. . The third round is to watch the big screen and answer questions. This is a story about a squirrel. When watching this short film, because of the cute and naughty image of the squirrel, the stadium was full of laughter. Everyone was chirping, it was lively, and the atmosphere was a bit loose. I came down, but I didn’t dare to relax and carefully captured the possible problems in the video. As expected, the host picked up the microphone and a new round of questions began again: "How many times has the squirrel stepped on the stone?" I saw someone rushing to answer the question, shouting "three times", "five times", I raised my hand high and answered loudly: "four times". I saw the host gestured "OK" and got extra points. I couldn't tell you how happy I was. Although it was a simple question, it was clear that carefulness was crucial. ...The game is still going on, the atmosphere is still very lively, and I have learned a lot from it. But I didn't get good results. I think this is all about participation.

The game is over. I feel that community activities have added to my summer activities and enriched my summer life. I will participate in more community activities in the future.

I am very curious about many things, just like once, the alarm clock my mother just bought was broken by me on the same day. Because I felt that its second hand seemed to move faster than the big clock outside, I wanted to take it apart and take a look, but the second hand fell off and was lost. I always like to ask my mother this question and that question. My mother is often confused and unable to answer. Therefore, this year we just had summer vacation, and my mother couldn’t wait to buy me a copy of "Touch Science" for me to read while I was resting at home.

I studied the whole book carefully. There are many interesting scientific experiments in it, such as magic with boxes, ice bricks cutting continuously, clavicle technique, etc. My favorite among them is "Clavicle" "Skill" is very fun. In order to show it to my family, I secretly practiced it alone in my room. First, I stood facing the wall with my feet together, straightened my arms, and adjusted the distance between myself and the wall so that With your fingertips just touching the wall, keep your arms straight, swing your arms downward to the back of your body, and then pull your arms back to their original position. At this time, your fingertips can no longer touch the wall. Hey, my arms seem really short. It was so fun. When my parents came back from get off work, I immediately performed magic tricks for them. They were stunned for a moment. Does anyone understand the reason? I have to decipher it: In fact, it’s not that the arms are shortened, but that when you swing your arms behind your body, you unconsciously lean forward in order to maintain your body balance. When you swing your arms forward again, in order to maintain body balance, your body will unconsciously tilt backwards, causing your arms to "shorten" and no longer touch the wall.

We must learn science, love science, and use science. It is actually around us. 10 Excellent Popular Science Essays

I have always liked reading books in the princess series. A few days ago, my aunt came back from a business trip and gave me a set of "One Hundred Thousand Whys", so I started to try to get in touch with popular science books. .

You won’t know if you don’t look at it, but you will be shocked when you look at it. It turned out that popular science readings contained endless mysteries and wonders, which attracted me all of a sudden. The "whys" I had ignored all of a sudden suddenly aroused my interest in scientific knowledge: Why can't you drink boiled water that has been boiled repeatedly? Why can gas masks protect against viruses, etc.? What interests me the most is why washed eggs tend to go bad easily? I looked at it with curiosity, oh! It turns out that there is a layer of gelatinous substance on the surface of freshly laid eggs that can block these holes in the eggs. This gelatinous substance can be dissolved in water. Therefore, when the dirt on the eggs is washed with water, the gelatin is also washed away. In this way, the tiny holes in the eggshell act like open windows, allowing bacteria to enter, so the eggs spoil quickly.

It turns out that there are so many "whys" that I don't know in life, but I have never cared about these "whys". Today’s reading opened a door to scientific inquiry for me. Because there are endless “whys” in the world waiting for us to discover and explore. Therefore, we should study hard now, think hard and ask questions, and provide first-class science and technology for mankind in the future to benefit everyone.

I like this set of books so much because it makes me understand that I need to study hard and learn more new knowledge! Excellent Popular Science Essay 11

We saw some other animals on the publicity board on the wall: some were birds, some were reptiles. My mother and I came to the bird area, and the first thing we saw was the peacock. In the picture, the male peacock spreads his long and colorful feathers and is wooing the female peacock!

In the second picture of hummingbirds, I know that hummingbirds can hover and fly straight up and down. Here I learned that hummingbirds can also fly backwards. Some hummingbirds can beat their wings up to 90 times per second. We saw many more birds, such as yellow-throated babbler, red-crowned crane, bee-eater, skua, and bare-browed thrush. My mother and I walked forward again and saw the exit, so we walked out of the knowledge display area.

Go to the second floor, the tropical rainforest exhibition area. As soon as we went upstairs, we saw a cicada being held by a huge mantis. The mantis was cutting the cicada with its scythe. The cicada was in great pain and was running away, but in the end the mantis caught the cicada. .

Chirp, chirp. I looked behind the praying mantis. Wow, I was shocked. It turned out that there was a oriole behind the mantis! The oriole is staring at the mantis eagerly! At this time, I suddenly remembered an idiom: the mantis stalks the cicada, and the oriole follows.

Hey, doesn’t this reflect the story of the mantis stalking the cicada, followed by the oriole? I told my mother what I found, and she also said: Yes, it does reflect the saying that "the mantis stalks the cicada, and the oriole follows behind." But, how come this praying mantis is many times bigger than the oriole? Excellent Popular Science Essay 12

Today, the global population has reached nearly 7.6 billion, and it is still growing. In order to solve this problem, people have the idea of ??building aerial cities.

People built huge cities in the sky just like building elevated highways. People say: "Will it block the sun on the ground after it is built?" Actually, there is no need to worry! It can shrink! Time flies so fast, and it’s the Spring Festival of 20xx in a blink of an eye. On this day, people received a greeting card from an alien planet. The aliens wanted to visit the earth!

A few years later, aliens arrived as promised. We take aliens to visit the Earth. They are very curious about the Earth and like it very much and want to settle here. Due to the arrival of aliens, the population of the earth has increased again, and even the sky city cannot be accommodated. So we built Ocean City and Dungeon City again. Ocean City is mainly made of glass. On a sunny day, the sun shines on the sea, making the whole city shiny and spectacular. There are many transparent glass tubes connecting the land and Ocean City, and people can go from land to seabed in the blink of an eye on trams. Here, people play with clownfish, greet dolphins, and hide and seek with Uncle Octopus and Miss Crab anytime and anywhere... At night, the starlight in the sky shines through the sea and glass, like natural crystal lanterns. , emitting a dazzling light in the darkness. People fall asleep listening to the sound of the waves, and with a good night's sleep, they feel at ease and at ease.

Underground cities, as the name suggests, are cities built in the soil underground. They are also the favorite cities of aliens. They absorbed minerals in the soil and converted them into energy for use, and invented many new and interesting things.

Okay, let’s not talk anymore, I’m going to explore Sky City. Excellent Popular Science Composition 13

Today, my mother bought me a popular science book about animals.

Before humans appeared, the earth was ruled by a group of huge and extremely strong creatures. They lived unrestrainedly in the ancient land, sea and sky. The earliest rulers of the earth were dinosaurs. After the dinosaurs became extinct under natural conditions, the originally humble mammals gradually underwent tremendous changes. After millions of years of evolution, they eventually became prominent creatures on the earth. The slender tail of the long-nosed jerboa seems to be very suitable for catching insects. In fact, the long-nosed jerboa also likes to catch snakes for food; sometimes, some small mammals also become food in their mouths. The appearance of the Nikuru monkey is very strange, with a big head, big eyes, and big ears. Their orbits are narrowly spaced and their tympanum is tubular. Nicorette monkeys have sharp teeth that they can use to crush insect shells. Fossils of Nicolo monkeys were discovered in Western Europe. Over hundreds of millions of years, nature has created tens of thousands of species in the process of life evolution. From 240 million years ago to 530 million years ago, there were many monsters living on the earth. The cruelty and weirdness of these monsters are far beyond our imagination. Although they are all extinct now, fossil research proves that they are indeed among us. Planets appeared before, and even became powerful for a while, ruthlessly competing for hegemony on the ancient earth. About 200 million years ago, mammals began to appear on the earth. These animals had hair or villi on their skin and fed their young with milk. They are warm-blooded animals and are able to generate their own heat and maintain their body temperature even when the weather gets cold. The earliest mammals were tiny, insect-eating animals that looked like mice.

The earliest mammals laid eggs and reared their offspring with milk. These animals were called monotremes.

I learned a lot from this book, and I’ll talk about the rest next time! Excellent Popular Science Essay 14

Some people think that science is difficult to understand, while others think that science is too profound and difficult to explore. In fact, science exists everywhere around us, and no matter how big or small it is, it can be solved with scientific methods.

Let me talk about the small matter of chopping firewood. Maybe many people think that chopping firewood is a simple matter, just pick up an ax and chop hard. Not really.

One day, my father bought back a large bundle of firewood, looked at me with a smile and said, "Yujie, how about we compete today to see who is more capable?" Of course I refused to bow my head. Isn't admitting defeat just chopping firewood? Don't believe I can't do it.

The game started, and my father started to chop easily. I also used all my strength to chop. At this time, I found that my father was so light in chopping firewood, and I thought: "Humph, it must be my father who left the sharp ax to himself." I calmly said to my father: "Dad, let's change the axe, I like you That one." Dad exchanged it with me without saying a word. My ax came into my father's hands, and he felt like a fish in water, and he worked even better. Not long after, my father's portion was completed. Looking at me again, my hands were blistered and sweating profusely from exhaustion. There was still a long way to go before completing the task.

I have to admit defeat, but I must lose clearly. I asked my dad: "Why is this happening?" Dad said: "If you don't split along the grain of the wood, it will waste a lot of effort. But if you use scientific methods and split along the grain of the wood, it will save a lot of effort." . And if the firewood is very long and you want to chop it, you can't put the firewood flat on the ground, but have to lift it up. This will break the firewood. "I used the method my father said to chop the firewood. It was finished in a short while. The scientific method is really useful, I have to admit defeat.

Although I lost, I am very happy. I have gained another life experience. Science is all around us. Excellent Popular Science Essay 15

Today, I had nothing to do, so I ran downstairs to play.

As soon as I arrived at the open space, I saw a little ant under the iron tree basin. There was a dead dragonfly next to it. It looked like it was transporting the dead dragonfly back to the cave. But how can a tiny ant move? Judging from the way it turns around, it must be thinking of a solution.

After a while, it went back alone, and I thought it was going to give up. But who would have expected that within a short time, a large group of ants would come out of the hole where it entered. Oh, it turned out that I was looking for "reinforcements". The swarm of ants picked up the dead dragonfly and walked back.

I wanted to play with them, so I thought of a way to block their way with various small stones. But they seemed to have a compass and headed towards the cave entrance. So I took another stone and threw it on the dragonfly. The ants ran away quickly. I thought they would give up, but they came back along the original path and continued to lift the dragonfly. And with their "great strength in numbers", they finally carried the dragonfly into the hole, and broke it into pieces and carried it into the hole.

I really don’t understand why they have such a strong ability to recognize roads. With this question in mind, I checked the relevant books. Finally I found the reason in an encyclopedia. It turns out that ants have a secretion with a unique smell - tracer hormone, which is excreted from the anus. When an ant on a patrol discovers food, it drops these tracer hormones on its way back so that other ants can smell the secretions and find it. In this way, even if their route is temporarily interrupted, they can still find their original route by smell.

I am so happy, I have gained another piece of knowledge.
