In our daily life, everyone will inevitably come into contact with composition, which is a comprehensive and creative speech activity. What kind of composition can be called an excellent composition? The following is a 400-word composition for primary school students' science and technology festival. Welcome everyone to learn from it, I hope it will help you.
Primary school science and technology festival composition 400 words 1 The wonderful science and technology festival launched by the school in May is drawing to a close. Before the end, each class will hold a demonstration activity. The content of the exhibition is the plants planted by students and the observation record table.
On May 9th, it was our class's turn to show, and 10 many students participated in the arrangement of the show activities. We are divided into preparation group, art group and speech group. The students in the preparatory group are responsible for arranging the exhibition hall for students to visit and enjoy, and preparing the props needed for the activity: tickets, seeds and candy; The art group is responsible for painting posters and beautifying the exhibition hall; The lecture group is responsible for explaining plant knowledge to students. Xu Kuan and I are in charge of taking pictures.
The exhibition has started and everyone is very busy. Everyone is absorbed in his work. I look around with my camera and never miss a wonderful place. When you are free, you can also help the students in the lecture group explain the knowledge of plants and help everyone maintain the order of the exhibition hall.
At half past twelve, the climax of the exhibition arrived. More and more people come to visit, and there is a long queue at the door. At first, in the face of an endless stream of people, everyone was as busy as a headless fly. Gradually, everyone's cooperation became more and more tacit. Under our orderly control, the venue was orderly.
Throughout the afternoon, we managed the order of the venue unhurriedly, and with the joint efforts of everyone, the exhibition was a complete success. In this science and technology festival, we not only gained planting knowledge, but also exercised our ability. Young Pioneers in Class 4 and Class 6 are more capable of independent activities!
The sky is particularly blue, the sun is particularly warm, and I am particularly excited. Because the school's annual science and technology festival has already opened!
At the opening ceremony, there were many magical and interesting programs, among which, my favorite was the program in which two students performed a water rocket flying into the sky. They first took out a paper rocket, put it on the launcher, then pumped it up with a pump, and finally pulled out the pump, and the rocket flew into the sky with a swish. At this moment, I thought to myself: how can I fly so high without fuel? It's incredible! Just when we looked puzzled, our classmates told us the principle of water rocket flight. It turns out that water rockets can jump up by the thrust of air and water.
Although the performance in the morning was fun, the garden activities in the afternoon were even more exciting!
There are more than twenty activities in the afternoon, all of which are very challenging. Among them, my favorite is the pen cap diver in Class 6 (2). This is to make the submerged pen cap float to the surface. First, fill the cup with half of water, put the pen cap into the water, and squeeze it hard, so that the pen cap will float and sink after being released. I stared at the pen cap, still wondering what caused this phenomenon. At this time, the students explained the principle to us, because the bubble size of the floating cover in the gas cap determines the fluctuation of the cap. Oh, I see. It's an eye-opener.
What a fruitful day! Science and technology festival not only has interesting experiments, but also makes me interested in science. I love science and technology festival, which makes our life more interesting and magical!
The pace of science and technology has quietly entered our campus, and the annual "Science and Technology Festival" has begun.
What we are looking forward to most is the interesting eggs hitting the earth! Teacher Xie "gave the order", and we rushed out of the door and watched the game with great interest. It is our class's turn. He used balloons as buoys. This is to use the buoyancy of the balloon to slow down the falling speed of eggs. Now he holds the egg with bamboo and holds it with a rope. When the balloon descends, the bamboo frame can cushion the descending impulse and prevent the egg from breaking. The work he made was a success, and the egg was not damaged at all. Teacher Wu checked the homework and weighed it, which was completely up to standard. The result was announced, and he became the top ten player.
The next activity is my favorite, which is the demonstration of scientific and technological inventions. Teacher Xie took our class to the first floor to see students' works, many of which were made of some waste materials. Some are magnetic thermometers, some are small electric lights, some are pizza made of waste paper, and some are small inventions such as multifunctional daily necessities. Students' spirit of innovation and environmental protection is worth learning.
After the Science and Technology Festival, I thought: If we work hard, our life will be full of fun. A famous person once said: Technology is productivity. Children in our new era should use science and technology to revitalize our country and make our country stronger.
Today we have a campus science and technology festival competition, and leaders and guests will come to watch the performance.
The first is the appearance of the bugle team. Rhythmic drums and clear trumpets are very pleasant to listen to, and then there are square performances with the characteristics of each class. The first one to appear is haimo of class five. The students walking in the first row all hold a picture of a boat in their hands, and the students behind them hold a blue cloth, which looks like a real boat as a whole. The most striking thing is the balloon performance of Class Two. Everyone in Class Two has a beautiful balloon in his hand. Colorful balloons are very beautiful! Suddenly, all the students released their balloons. In an instant, colorful balloons slowly rose into the blue sky, and all our classmates turned their eyes to beautiful balloons. Many students said, "How beautiful!" Our class is not to be outdone, and now it's our turn to play. Suddenly my heart is beating fast, I think, I must go! After a while, we started to walk. Each of our classmates was holding a globe, which was very beautiful! The slogan of our class is: "Love mother, protect the earth, explore mysteries and live in harmony." The meaning of this sentence is to protect our living environment like a mother, study science and make our life better with science.
Next, the winner of the badge design was announced. What excites me most is the prize-winning activities of science and technology stars. Because this time, Hehe in our class was rated as the science and technology star of our school. When the leader wore a badge for me, I proudly gave him a team salute. I feel extremely honored and determined to continue to work hard. Finally, there are four-wheel drive competitions, painting, solve riddles on the lanterns and other activities.
The wonderful and interesting campus science and technology festival ended with laughter. This science and technology festival makes me unforgettable. I hope our campus will always be full of love, study and application of science.
In the last few minutes of science class, the science teacher unexpectedly told us that tomorrow is science festival.
After class, the classroom suddenly exploded, and the students cheered and talked about it. Because the science and technology festival that we miss so much is finally coming!
The next afternoon, our class went to the Science and Technology Festival Garden. As soon as I got downstairs, I was stunned by what I saw. The students are so crowded that it is difficult to squeeze in and have a look. On the playground, a huge model airplane flew in the sky with colorful ribbons, which attracted many curious eyes. Some scientific and technological works are water-turned windmills. It's the first time I've seen water as a power source to drive windmills! Some scientific and technological works are remote-controlled cars, driving happily in freedom. Some scientific and technological works are mechanical arms with a pen in the middle. A classmate took the remote control, pressed a switch and asked the mechanical arm to write. Among them, I am most interested in a paper shell full of needles. I put a balloon on it. As soon as I put it down, we ran away because we were afraid of the sound of balloon explosion! But looking back, the balloon is safe and intact. It turns out to be the principle of air, which really makes people sit up and take notice!
The bell rang and we left step by step. This science and technology festival really opened my eyes and feasted my eyes. I hope every science and technology festival is so interesting!
Primary school science and technology festival composition 400 words 6 people have joys and sorrows, and the moon is full of rain and shine. Today, I am very happy! Happy, because I have an interview again today!
Today is our school's annual science and technology festival. There are colorful sci-fi paintings, various small productions, vivid and interesting scientific compositions and on-site paintings. Of course, I also joined the ranks of live painting.
In the afternoon, I began to draw. I know where to put the pen. Time is running out, and my first painting is gradually taking shape. Unexpectedly, a tall uncle with a camera and an aunt with a microphone stood in front of me. I crustily skin of head to continue painting. A few minutes later, I finished painting.
My aunt said to me with a microphone, "Shall we ask you some questions?" Suddenly, I seem to be startled. They want to interview me! My heart is frozen, so there will be no problem of saying the wrong thing. What should I say and what should I not say? I looked nervous, but I finally answered their questions with a smile and broke out in a sweat. I jumped three feet for joy. Great, the sweat on my head disappears instantly, and my face is full of joy. However, I will continue to work hard.
I had an interview today.
Primary school science and technology festival composition 400 words 7 We ushered in our school's annual sports science and technology festival. At the Sports Science and Technology Festival, we will hold a series of sports activities at school, including running, high jump, tug-of-war and whirlwind eleven people.
I was chosen as a 200-meter athlete by the teacher, with three people in one class. I am one of them. The 200-meter athletes are elites from all walks of life. I am a little scared, but my confidence keeps flowing into my heart, because the whole class is encouraging me to win glory for them and fight for the class.
Finally, the annual sports festival began, and everyone was very excited. I was assigned to the third round of nervousness. I am very nervous, shivering and stressed. The challenge is that the classic is ready to start, and a gunshot, "Bang!" Everyone set out at the fastest speed and shot out like an arrow. I tried my best to overtake two people at the second corner, when the whole class cheered and applauded. The whole room is boiling, and I am more motivated.
I looked at it with my eyes and my opponent was not far away. At this time, my opponent is as hard as me, his face is blue and his lips are white. As long as I work harder, I can surpass him. So I secretly cheer for myself in my heart! Overtaking three people in the third corner, I felt I was going to lose because I was weak, but I remembered what my classmates and teachers said, and I insisted on not giving up my expectations of my classmates. There was a loud refueling sound in my ear again. "Guo Ye, come on!" "Guo Ye, come on!" When I grind my teeth, I suck milk with my strength. Finally, he finished the race with the third place at the finish line. At the moment I stood at the finish line, I sat on the ground, surrounded by classmates, still praising me.
I know there are people outside the world in this game, so don't let anything go, let alone give up halfway. Because persistence is victory, and giving up is failure.
Today's sunshine is particularly bright, and the warm spring breeze blows away colorful flowers. The school playground and gymnasium are crowded with people, and the 29th school science and technology festival is in full swing.
I was squeezed among dozens of students on the basketball court. Everyone took their beloved four-wheel drive and tickets and lined up on the winding track, always ready for the start of the game. With the teacher's command, the first red four-wheel drive flew forward along the track like an arrow. The owner is a fourth-grade boy with his eyes fixed on the car and a little sweat on his forehead. When the car came to the corner, his eyes widened with nervousness. Fortunately, the car turned the corner smoothly, and he took a long breath. When the car was returned to him after the game, he jumped for joy. It's our turn to Shao's blue bike. His car is equipped with a high-power motor, full of energy like a blue BMW. Climbing high slopes is very easy. It's almost the corner, BMW is still running, and we are all sweating for him. In the blink of an eye, I heard a bang. The BMW overturned and fell to the ground. There is a sigh around.
The "super bubble" game on the playground also attracted many students. Under the sunlight, big bubbles emit colorful light, which is very interesting. There are also cheers and exclamations on the stadiums of drones and rubber-band powered aircraft.
Our science and technology festival is so happy and interesting!
Primary school science and technology festival composition 400 words 9 in the morning when everything is reviving and spring is bright. I walked to school with my schoolbag on my back. The sun is high in the sky. It is warm and refreshing. I am very excited. That's because the annual science and technology festival in our school will open today.
In the weekly class, I heard from the radio that the content of this year's Science and Technology Festival is to plant flowers and plants in each class, and also to mobilize students to bring the waste newspapers at home to the class, collect the money they sell and buy all kinds of flowers and plants, and use the students' rich knowledge of flowers and plants to cultivate their sentiments. As soon as I entered the classroom, a lot of newspapers appeared in front of me. The newspaper, which was to be handed in next Monday, is unexpectedly enthusiastic about students attending the science and technology festival. Within a few days, the newspaper in our class sold for 40 yuan and bought seven pots of flowers, but after all, we had too few flowers. My classmates and I also brought our own flowers. Some people brought peppers, strawberries, sequoias and roses. ...
The classroom is full of colorful flowers and smells everywhere. Some students made slides, and almost no pot with so many flowers is the same. In this science and technology festival, natural science also has the task of planting. Teacher Du asked us to grow onions in groups, and the students were ecstatic. It didn't take long for our onions to grow tender roots. Some groups of onions have grown green leaves like jasper, which I and other groups are envious of.
Through the activities of the science and technology festival, students have increased a lot of knowledge about flowers. This year's science and technology festival is coming to an end, and everyone is looking forward to the next science and technology festival!
Primary school science and technology festival composition 400 words 10 Today our school holds a science and technology festival.
The fierce competition and rich scientific and technological exhibits at the science and technology festival are really dazzling. The science and technology festival began with a Newton's disk competition. In the cheers of the students, the Newton of the player turned quickly and buzzed. After a while, the game was over and my heart was pounding. Did we win? Don't you know? It is said that it will be a long time before the results of the game will be broadcast.
Next, it's my turn to participate in the racing king race. I picked up my beloved racing car with confidence and followed the footsteps of my classmates, thinking while walking: I must win the championship! I just came to my senses when I thought it was my turn before I knew it. I started the car and slowly put it on the runway. At the referee's command, the car started to run quickly. One lap, two laps, three laps soon finished three laps. It took me a little more than 6 seconds, not the best, but still very happy.
After the game, we followed the teacher to the science and technology exhibition. First, we saw 3D exhibits. After I put on 3D glasses, I saw that the animals and plants were really lifelike and scary. I also put my finger on Barry, the big mouth of Tyrannosaurus Rex. It was fun. Another interesting science and technology exhibit is a cylinder with several horses painted on it. Turn it around and look through the hole on the side. You will see many horses running. Well done! Another fun thing is that there are two hand-shaped batteries. I feel warm when I put my hand on them. I put my hand on it. Hey! It burned me to death! This thing is really strange. How did it get hot? How can I make these things? Dad told me that only by studying hard will I know its principle in the future.
Composition of Science and Technology Festival in Primary School 400 words 1 1 "Look, this is my composition." "Look, how beautiful it is!" "Wow, how are these papers made? There are pictures on it. " After reading these, do you know what our school is doing? To tell you the truth, this is the annual science and technology festival being held in our school.
Speaking of popular science exhibitions, there will of course be countless popular science exhibits. Look, we did "turning waste into treasure" in the fifth grade. Old CDs are assembled into exquisite vase holders; Old paper tubes were made into festive firecrackers; Old cloth, woven into lovely bags ... really dazzling. Let's take a look at the person who showed us how to be a "baby"! Look, it's very clear. I saw a female classmate holding a needle and thread in one hand and a small doll in the other, carefully embroidering on a piece of cloth, sewing intently like an adult. Of course, the students in our class are not inferior. I saw Wu with scissors in one hand and sponge paper in the other, and he cut it with a click. A few times later, a cute little octopus made of CD was born.
Let's look at the sixth grade again. Their popular science achievement is "papermaking"! This is a magical word. Who is so awesome and can make paper? I'm like a 20-foot monk-I can't figure it out. Murphy, our school has produced the second generation of "Cai Lun"? I strode to their paper-making area and looked at every piece of their work carefully. Some are like a smooth mirror, but the reverse side is very rough. Some are like rough magpies, but there are beautiful pictures on them. They also demonstrated the production process and let me know the production process.
I am so happy at this year's Science and Technology Festival. I not only learned a lot, but also gained a lot of happiness. I hope the Science and Technology Festival will come soon next year!
Primary school science and technology festival composition 400 words 12 The annual campus science and technology festival is here again. The first activity of this science and technology festival is "lovely ice necklace". I thought curiously, "A necklace is a necklace, and ice is ice. Why is there an "ice necklace"? I am looking forward to the beginning of the experiment with doubts.
The teacher began to distribute materials. When she heard the teacher say, "Please ask the fourth group to get the materials." Pei Hanyang and I ran to the podium in two steps. Pei Hanyang holds a washbasin in his hand, holding a large piece of ice. I strode to my seat with white salt in my hands.
After receiving the materials, we listened carefully to the teacher's explanation: "Students, to make an ice necklace, we must first put the cotton thread prepared at home on the ice, and then sprinkle salt on it. Here is an important tip, that is, cover all the lines on the ice with salt, then wait 30 to 60 seconds, and finally lift the rope ... "
"Ready, go!" I only listened to the teacher's instructions, and we started experiments one after another. I put the thread on the ice first, and then sprinkle salt on it. I silently counted: "One, two, three ... twenty-nine, thirty!" " Just as I picked up the rope, I heard a thump, and the ice fell off the rope in my hand. "Could it be that the ice is too heavy and fell off? Will there be less salt on it? " I meditated for a while, then picked up a piece of ice and started the second experiment. "Fifty, sixty!" With the completion of the last step, I lifted the ice. Ah, I made it! I cheered excitedly. Teacher Lin saw it, and with a click, I recorded my moment of success with my camera. I'm so happy!
Time flies, and the activity of making "ice necklace" is over before the fun. This beautiful memory has been deeply imprinted in my mind, and I look forward to the next activity again.
Composition for Primary School Science and Technology Festival 400 words 13 Thursday is an unforgettable activity of Science and Technology Festival-Science and Technology Garden Party (Expo).
The teacher first gave each of us a list, folded it in half and told us, "Each of you should play games with this paper in every class. After you finish typing, you can go to the exit and stamp it, which is divided into two chapters: one. Experience, as long as you operate, you can get 3 points. Two. Operation chapter, complete a game and get 5 points. You can go now. "
We set off in high spirits. There are many items on the list, such as: the first category (1), closing your eyes, and the third category (Shenshui). I went to Class 5 first (1), and the theme was singing science and technology. Then I went to Class 5 (2), put coins in the cup and played table tennis (4).
I think the most interesting thing is the paper bridge bearing of Class 4 (2). The rule is: build a bridge with newspaper and put it on the math book for 30 seconds, and put a paper cup on it. If the bridge doesn't fall down and doesn't move, it means you have succeeded! How did I do it? I first folded the paper bridge with a folding fan, then put it on the math book and put a paper cup on it. The bridge didn't move. "Yes!" I'm happy to put the action stamp on it.
After the Expo, I summed up my scores. Oh! Yes 100! Next, I won the science and technology chapter, participated in art exhibitions of various classes with my classmates, and visited the first prize works in the hall. I thought to myself: where is my job? Ah, my work is hanging gloriously in the hall. I am so happy in my heart! I don't want to mention how happy I am when I hear a girl praise my painting for being beautiful and beautiful!
This painting won the first prize and was collected by the school!
What a happy science and technology festival. Let us gain knowledge in happiness and feel the wonder of science!
Primary school science and technology festival composition 400 words 14 Today we ushered in our long-awaited science and technology festival. This science and technology festival is really full of twists and turns. The science and technology festival, which should have been held long ago, was pushed to today by that hateful rainy day.
This science and technology festival held an activity that has never been held before: Life Skills Competition! See who can finish dressing, putting on pants and tidying up the schoolbag in 2 minutes. At first, all the students were hands. Wear this and forget that. It doesn't look good after wearing it for a long time. Everyone else is very calm. They put on their clothes and put on a red scarf leisurely, and finished their work early. The audience shouted at the audience and kept urging those students who were naked. The noise is so loud that I'm deaf! Nowadays, almost all students live a life of reaching for clothes and food, so holding this activity to exercise our self-care ability can make our life better! Don't depend on your parents!
We also held a bridge-building activity. Eight people in each class divided into two groups to build a straw bridge, and the height of the bridge reached more than 10 cm in 40 minutes. In this competition, everyone not only cooperated, but also felt a sense of collectivity. Everyone is winning glory for the class! After the bridge was built, the students learned through the load-bearing competition: how can we maximize the load-bearing capacity of the bridge? Let's learn by playing and learning by playing, which greatly stimulates our desire for learning and makes me understand that the only way to test the truth is practice.
Activities in the lower grades are more interesting. They made aerodynamic rockets. When they finished, they launched them in the competition. Some of them went straight into the sky, but before flying far, they quickly fell and touched the ground. Some of them have just launched and touched the ground. Some angles are well grasped, but the rocket exploded during the launch!
Through this science and technology festival, I understand that only practice can yield something!
Primary school science and technology festival composition 400 words 15 New Year's Day has arrived, and the school has carefully prepared celebration activities for us: the morning club performance and the afternoon science and technology festival, among which the afternoon science and technology festival is what I look forward to most.
The science game in our class is a "floating needle" on the water. At the beginning of the activity, I walked to a washbasin and carefully put the paper clip on the water. I thought the paper clip would sink to the bottom immediately, only to hear the staff shouting excitedly: "Wow, you succeeded?" The paper clip you put floats on the water! Full marks! " "ah? What? Not heavy? " I'm confused. "Why do paper clips float on the water?" Although I got full marks, I still don't understand. I almost bumped into the door when I was walking. Teacher Luo laughed when he saw my "lost heart". He said, "There is tension on the water, so the paper clip can float on the water."
Oh, I see! The doubts in my heart were finally solved.
"Fireline crossing, this name is so cool, it must be fun." I walked into the next playground by myself. I saw a table as soon as I entered the door. There is a tool on the desk. That's a plastic board. There are two batteries on the plastic board. There are two wires on the battery. I took one wire and bypassed the other, but the two wires couldn't touch each other. Finally, I got full marks. I think this game must also contain some scientific truth. I must find out after school!
I played all the games one by one, and every game brought me great surprises and gains.
This science and technology festival is really interesting!
