1. Composition: go to the labor base early in the morning, the fifth grade full of expectations to sit in the car is preparing to start. The silent car makes a lot of noise, just like a bird in a cage is free again
"here we are at last!" I couldn't help shouting out in the car. As soon as I got out of the car, I was unconsciously taken to the ecological science and Technology Museum. Why? What a beautiful nature! At first glance, it turns out to be fake
listen to the lead teacher, there is a place to experience the earthquake. I am full of curiosity: is it as scary as a haunted house, or as dangerous as reality? I look at it with questions. It's like a maze here and magma there., All of a sudden, there's a scream coming from the front. What's the matter? But I saw the front saying, "what's this? It's fun!"“ This is the earthquake& quot;、 What is this? You girls are too timid! " Some students nervously paid the railings around. If the magnitude of the earthquake is so small, will the students be so calm
after the thrilling simulated earthquake, the most profound thing I've been marketing is magic house. First came the uneven land, many people up and down quickly, and then saw the magic paintings on the wall. Although I saw these in QQ space, I still watched them for a while. Then, we went to the butterfly museum in the magic house. One butterfly specimen was hung on the wall, which made me mbfounded. The most attractive insect to me is the butterfly. When the butterfly flies, it has a beautiful posture. Its front wings are black, and its back wings are golden yellow and black. Under the sunlight, it looks gorgeous and beautiful. It is a large and beautiful species. Such a beautiful and elegant butterfly is nailed here as a specimen. If she lives, she will dance and leave a beautiful arc....
how amazing the eco science and Technology Museum is, it's an eye opener to me; The day passed quickly, which made me unforgettable

2. It's all the same there. The question is whether you need to learn from your heart or not

3. When Mr. Xu finished his report, he announced: "the summer vacation officially begins!" We like happy birds, happily ran out of the school gate, open arms cheering "summer vacation! We are looking forward to you at last Ha ha, finally can relax! Surfing the Internet, watching TV, playing games... We are dancing, laughing, looking forward to...
but the summer vacation is really coming. It's not what I thought. What's welcoming me is a more arous learning task: English cram school, composition cram school, Mathematical Olympiad cram school... The summer vacation has become the third semester of my academic year
every morning, my mother would wake me up from my sleep, wash and eat breakfast, and then rush to make up for English, composition and Mathematical Olympiad. Not even a breath. In the evening, I can be spared. I have to finish all kinds of strange homework assigned by the tutor. Occasionally do it carelessly, the next day also can't escape by the teacher scold
it's hard to get to the end of the tutorial, but most of the summer vacation is over. This should let me have fun! But in front of me, I have been busy in the cram school, and I haven't moved a word of the summer vacation homework assigned by the teacher. Of course, my mother won't let me play happily, nagging in my ear every day: "my son should seize the time to do summer vacation homework!"“ No TV That afternoon, my mother went out and asked me to do my homework at home. But as soon as my mother went out, I finally couldn't resist the temptation and turned on the TV in a hurry... Just as I was amused by the interesting cartoon, I was so excited

4. Guangdong science and Technology Museum
today, I organized Guangdong science and Technology Museum in my school. This activity really opened my eyes and touched me a lot
in the science and Technology Museum, there are both original tropical rainforests and modern scientific and technological achievements. From micro atom to macro universe. We are surrounded by small computers that can be operated by ourselves. From the mystery of insects to the greenhouse effect of the earth, we can harvest countless fruits with a little touch. Science and Technology Museum is like an endless network book, but it's not boring at all. Once you hold it, you can't help but linger
I came to "aerospace world" for a visit. In the space world, I saw the model of GPS global positioning system and the four axis balancer, a training device designed to improve astronauts' ability to achieve body balance and self-control consciousness in three-dimensional space. The four axis balancer tests the astronauts' ability to adapt to the environment and self balance by simulating the rotating state of the spacecraft. I also experienced the flipping training of an astronaut. Although the speed was much slower than the real training, and it was only a minute, I really realized the difficulty of astronaut training
one of the exhibition items is "peeping at infinity". I think it's good. It is an optical phenomenon. Endless repeated images can be seen in the mirror. I gently rotated the frame with my hand and found that the positions of all images changed accordingly. I didn't understand what was going on, so I asked the science teacher who was visiting. The science teacher told me, "this is a reflective imaging optical system composed of two flat mirrors. The front is a semi transparent and semi reflective mirror, and the back is a full reflective mirror. When the two mirrors are in parallel position, they have the characteristics of multiple reflection and imaging. For example, if an object is placed between them, many images can be reflected. When the angle between the two mirrors is changed by rotating the frame, the position of the reflected image will also change e to the change of the incident angle of light. " After listening to the science teacher's explanation, I suddenly understood the cause of this phenomenon. I am happy that I have understood a physical phenomenon
on the bus back, I thought: today, when I went to the science and Technology Museum, I learned a lot of scientific knowledge. What I thought was impossible in the past, and what many people thought was impossible, has now been realized. It can be seen how advanced science and technology are now. Although I can only visit the things invented by others, I will study hard and invent more advanced high-tech procts for the benefit of society.

5. On Sunday, I visited Zhengzhou science and Technology Museum. From the outside, the north side of the science and Technology Museum is a cone, and the south side is like a square bread. Walk into the science and Technology Museum. There are three floors in it. The first and second floors mainly introce and demonstrate some scientific phenomena, such as electrostatic generator, robot that can play piano, earthquake demonstrator, sound room, etc. Through these demonstrations and introctions, we can easily know the causes of some phenomena. We can not only watch, but also operate and experience by ourselves. I got on the earthquake demonstrator with other children. It was shaking so much that the pen and paper in my hand were shaking off. Now I finally know the power of earthquake
on the third floor of the science and Technology Museum, there are some models of our country's "Long March" series rockets, as well as some activities for children to make by themselves
when we went, in the hall on the first floor of the science and Technology Museum, we were exhibiting some small inventions and creations made by our primary school students. For example, safety folding sickle, tool for changing light bulb, homemade small dressing room, etc. These are all small inventions and small proctions that have won the second prize or above. What impressed me most was the tool for changing the light bulb. It's a mop. There's a clip on the top and on the right. When changing a light bulb, aim it at the light bulb, and then screw a round thing to screw the light bulb off. In this way, people don't have to stand on a stool or a ladder. It's really convenient. These students invented these useful things at a young age, and they will be excellent inventors in the future. I also want to learn from them
ring this visit to the science and Technology Museum, I learned a lot and gained a lot.

6. With the development of science and technology as the center,
the wheel of history is rolling forward rapidly. Advanced science and technology has created our beautiful life today.
with the development of the times, countless sages have left us wisdom, truth and people's constant exploration, discovery, innovation, and the pace of human beings is moving forward< There is no doubt that the invention of automobile has greatly facilitated our travel and brought us many conveniences; Amazing achievements in agriculture; The procts and machines in the family room are constantly humanized, and many inventions have laid a good foundation for our life. The computer is a cross century creation, and we can't live without it, and we rely on it more and more. The computer can easily help us control many things, and can accurately calculate the data we want, To meet our various needs... Human's endless desire for knowledge drives us to face all mysteries without fear. We focus our vision on the distant and unknowable universe, and our mind on the endless unknowns.
heaven has endowed us with wisdom, which is destined to let us explore. The word technology is created by human beings, Also destined to bring us a better future! However, with the changes of the times and the progress of science and technology, the earth, a pure land where we live, has been damaged. Science and technology has brought us not only a beautiful but also new problems. Cars are the common means of transportation for human beings, but they need a lot of gasoline supply. Cars are used for a long time, and minerals are exploited unrestrained, The continuous felling of trees has devastated the earth. The greenhouse effect is spreading all over the world, making the weather extremely hot, snowy mountains begin to melt, and the beautiful scenery is quietly leaving us...
all this is not e to our human beings? In the pursuit of a better future at the same time, we should first protect their homes. Instead of using all means to achieve a higher demand for life without considering the consequences< The development and creation of science and technology make our life better, and at the same time, we should use our own technology to protect our homeland, make it brilliant and become a shining star in the universe!

7. The new China Science and Technology Museum is located in the Beijing Olympic Center, adjacent to the bird's nest and the water cube. The main body of the new building is a single square, which is not only like China's "Luban lock" but also like the Western giant magic cube, with the meaning of exploring and unlocking. The overall design is made up of several building blocks, which are combined with the characteristics of ancient Chinese scientific thought and modern science and Technology Museum
many parents come to the science and technology museum with their children to receive ecation. Some of them are still very young. Although they can't understand the materials and experiments displayed in the museum, at least let them cultivate their perceptual knowledge of something from an early age
the northwest area on the first floor of the new museum is the exhibition hall of Science Park, which is specially designed for children aged 3 to 10. There are 9 theme exhibition areas: know yourself, safety island, we work together, creative studio, happy farm, forest exploration, etc; In order to broaden children's horizons and know more about science, we specially selected a science park with strong interest and easy understanding for children to visit
walking into the Science Park, it's like walking into a science castle, a building block shaped house, "towering trees" around a circle of corridors, and a small simulated hospital with everything. Let the children see the X-ray, not only understand the interesting functions of the human body, but also know the importance of forming good habits. In front of the "happy farm" exhibition in the exhibition hall of Science Park, a child, with the help of his mother, became a tractor driver. He sat on the model of the small tractor and pressed the "select" button. On the wide screen, there were four items: stubble land, cultivated land, paddy field and harvest land. After he pressed the "select" button again on the "paddy field" project, the four cultivation stages of arable land, sowing, transplanting and harvesting appeared in turn. After pressing the "confirm" button on the rice transplanting project, he grasped the steering wheel, sometimes stepped on the accelerator, sometimes on the brake, and really had a "rice transplanting addiction"
in the space station, children can fly a "spaceship" to "see the earth", and they can also go through the "time and space tunnel" to simulate space exploration activities. During the "animal exploration", children can see all kinds of animal images on the LCD screen and discover the secrets of animals through such exhibitions as "looking for animals", "who are they", "experiencing flying" and "insect Games". In the water playing Bay, some games are designed, such as pipe games. Children control valves to let water flow to different destinations. Through transparent glass, they can see how to control water flow in pipes and understand the principle of tap water
through this visit to the science and Technology Museum, I feel that it's true that science ecation starts with dolls. Human life is the most precious. There is science everywhere in life. Science enlightens thinking, and thinking is the source of creation. While fully perceiving and enjoying the achievements of predecessors, we should transform our destiny with knowledge, adhere to the concept of low-carbon life, and make human life on the earth more and more beautiful!

8. Green wave primary school six year class Wujin Road

today, I am happy to come to the science and technology activity center with the whole class, and come to the green guard activity room that I yearn for day and night

the exquisite microscope, complete instruments, like a magnet, deeply attracted me. So that I changed my usual quiet, joined the ranks of bold experiment, practice and innovation

as the teacher asked our group to give a loud name from the first stage, I was very nervous all the time. It's the first time I've named a group. I want to jump out of my throat. I thought about it. Suddenly, I said, "it's called" green story. ". The team members applauded

I just finished drawing words. Look, hey, don't say, my drawing is good. The teacher praised me! The students are like each other

the teacher has another problem: let's do the experiment ourselves --- observe the onion epidermal cells with a microscope. I used a microscope for the first time. There's a sense of sacredness to the touch. I failed the first time. But we didn't lose heart. We learn from our failures. ha-ha! I won

happy, the teacher gave an order: turn the sewage into drinkable water. Now, I'm racking my brains to think about it. I'm as anxious as an ant on a hot pot. All of a sudden, a group of "colorful wings" composed of four students are circling around the instrument

all of a sudden, my team members and I came up with a very good idea

1

2. Filter the smile substance with gauze

3. Light the alcohol lamp and boil the glass of water. Using steam to make clean water. But in the third step, the experiment was in trouble for success. The beaker is very hot. Accidentally, a little water splashed out

through the unremitting efforts of me and my team members, we finally achieved success. Kung Fu is worthy of those who want to do it

the teacher told us another joke, and then the students around burst out a burst of laughter and played a scientific March. Looking at the happy background of the students, as if in a happy paradise. What an interesting science and technology activity! Let me enjoy the beauty of the instrument“ Appreciate the delicate microscope“ Taste the storm of "doing experiments"... This scientific and technological activity is like the bright Polaris, which is always treasured in my memory!

9. There are three pavilions in the science and Technology Museum. In the middle is the main exhibition hall. The dome shaped house on the left is the dome cinema, and on the right is the children's Science Park. We mainly visited the main exhibition hall. The pavilion has four floors and is divided into two areas. The fourth floor is the ancient exhibition area, and the first to the third floor is the modern exhibition area. In the center of the hall, there is a huge sign like a knot, on which there are colored lights that can keep flapping. It's very spectacular. We took a long elevator up the stairs, from top to bottom to visit, first came to the ancient exhibition area

inside the ancient exhibition area is an exhibition of ancient Chinese science and technology. As one of the four ancient civilizations in the world, China has created splendid ancient science and technology and culture. Centering on the four great inventions, this exhibition selects 12 subjects including ancient astronomy, mathematics, medicine, machinery, bronze smelting and casting, ceramics, textile and embroidery, architecture, etc. to show the scientific and technological achievements of ancient China. In the astronomical area, I saw the model of armillary sphere, which was used to measure the position of celestial bodies in ancient times. Its center is two intersecting circles, which are also wrapped with several circles. Around the four pillars, there are four lifelike dragons, head up, as if to swallow the middle circle. Then I saw a big white round basin with a needle in the middle. Its name was "white"; A sundial calculates time by the sun. Suddenly, something like a big drum attracted my attention. There was a flying dragon in every direction of its body. There is a bead in the mouth of the dragon. There is a frog under each dragon. According to the commentator, as long as there is an earthquake, the bead in the mouth of the dragon in that direction will fall into the mouth of the frog. This is the famous seismograph invented by Zhang Heng, which was specially used to predict earthquakes in ancient times

next, I went to the ancient agricultural machinery farm; There are mper, plough, plough, these kinds of tools. There is a foot pedal on the rollover, which is used to transport the water from the ground to the field at a high place. The harvester is used for threshing millet. It can separate the millet from the rice stalk. What surprised me most was the large loom. In a room made of wood, there was a loom of the spring and Autumn period. The threads were hung on it. The operator pushed it left, shifted it right, and lifted it up and down to weave strong and fine cloth. People in ancient times were really smart enough to invent so many useful and exquisite instruments<

after visiting the ancient exhibition area, we went downstairs to the modern exhibition area. This area has three floors, which displays more scientific and technological procts, including electrical, mechanical, aviation, transportation and energy procts, as well as the exhibition of Olympic mascots. These "Fuwa" are big and taller than me. People who come to visit want to take pictures with them. The teacher also took a lot of pictures for us. Next to Fuwa, there are many people watching the simulated starting device. A five meter track has been built in the stadium. There is a running-up device that can measure the number of seconds of your starting time. Many people try it. I want to go, but I can't squeeze in. From the third floor down to the second floor there is a very interesting place, called into the virtual world. It has a big screen with a football field and a football net, but no one. When people walk in, they can appear on the screen and play football on the screen. It's amazing! The most attractive one on the first floor is the robot band. This robot can do 32 actions of human beings. When the music rings, he concts the band just like a conctor. The "player" below is also made of steel and can also swing with the music. This is really the best band. There is also an automobile exhibition on the first floor, from the Ford in 1923 to the car models of the future, as well as the model of the maglev train! Modern science and technology has developed much faster than ancient times. No wonder it occupies three floors. Human beings are a process of continuous progress

after visiting the science and Technology Museum, we left reluctantly. As I walked, I thought, "I will study science and culture hard and grow up to be a scientist."
