The wonderful science and technology festival held 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 the classmates and the observation record table.
On May 9th, it was our class's turn to show, and more than 1 students participated in the arrangement of exhibition activities. We are divided into preparatory 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 the knowledge of plants to the students. Xu Kuan and I are responsible for taking photos.
The presentation started, and everyone was very busy. Everyone was absorbed in their own tasks. I took the camera left and right, never letting go of a wonderful place. When I am free, I also go to 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 cooperated more and more tacitly. Under our orderly control, the order of the venue was in good order.
All afternoon, we managed the order of the venue in a leisurely manner. With our concerted efforts, the exhibition was a complete success. In this science and technology festival, we not only gained the knowledge of planting, but also exercised our ability. The Young Pioneers in Class 4 and Class 6 have stronger ability of independent and automatic activities! 4 words 2
The sky is particularly blue, the sunshine is particularly warm, and my mood is particularly exciting. Because the school's annual science and technology festival has 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 whew. At this moment, I thought to myself: how can I fly so high without fuel? It's incredible! Just as we looked puzzled, our classmates told us the principle of water rocket flying. It turns out that the water rocket can take off in one leap by the thrust of air and water.
Although the performance in the morning was very interesting, the garden activities in the afternoon were even more wonderful!
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 pen cap that is submerged under the water float to the surface. First, fill a cup with half of water, put a pen cap into the water, squeeze it hard, and the pen cap will float upwards, and then it will sink when it is released. I stared at the pen cap, but I still couldn't understand what caused this phenomenon. At this time, the students explained the principle to us, because the bubble size of the floating cover in the air cap determines the ups and downs of the cap. Oh, I see. It's really an eye-opener.
what a rewarding 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! 4 words 3
The footsteps of science and technology have quietly entered our campus, and the annual "Science and Technology Festival" has begun.
what we are looking forward to most is that interesting eggs hit the earth! Teacher Xie "gave the order" and we ran out of the door quickly and looked at the game with great interest. It's our class's turn. He uses a balloon as a buoy. This is to use the buoyancy of the balloon to slow down the falling speed of the egg. Now he is holding the egg with bamboo and fixing the bamboo with a string. When the balloon descends, the bamboo frame can cushion the descending impulse and prevent the eggs from breaking. The work he made fell successfully, and the eggs were not damaged at all. Teacher Wu checked his work and weighed it, which was completely up to standard. The results were announced and he became the top ten player.
the next activity is my favorite, that is, the demonstration of technological gizmos. Teacher Xie took our class to the first floor to see the students' works, many of which were made of some waste materials. Some are magnetic thermometers, some are small electric lights, some are pizzas made of waste paper, and some are small inventions such as multifunctional daily necessities. Students' innovative environmental protection spirit is worth learning.
After the Science and Technology Festival, I thought: If we use our brains 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 rejuvenate our country and make our country stronger. Primary school science and technology festival composition 4 words 4
Today, we have a campus science and technology festival competition, and this competition also has leaders and guests to watch the performance.
First, the bugle team appeared. The rhythmic drums and clear trumpet sounds were very pleasant to listen to. Then, the characteristic phalanx performance of each class was performed. The first appearance was Haimo of Class Five. The students walking in the first row all hold a picture of a ship in their hands, and the students behind them hold a piece of blue cloth, which looks like a real ship 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 the balloons in their hands. In an instant, colorful balloons slowly rose to 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 jumped quickly, and I thought, I must go! After a while, we started to walk, and 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 as much as our mother, learn science and use science to make our life better.
Next, the winners of badge design are announced. What excites me the most is the award-winning activity of science and technology stars. Because this time, Li Xiuqi and He Wenting in my class were rated as the school's science and technology stars. When the leader wore a badge for me, I proudly gave him a team salute. I felt extremely honored and determined to continue to work hard. Finally, there are four-wheel drive competitions and activities such as painting and riddles.
The wonderful and interesting campus science and technology festival ended with laughter. This science and technology festival makes me memorable. I hope our campus will always be full of love, study and use of science. Primary school science and technology festival composition 4 words 5
In the last few minutes of science class, the science teacher unexpectedly told us that tomorrow is the science and technology festival.
after class, the classroom suddenly exploded, and the students cheered and talked about it. Because the science and technology festival we miss so much is finally coming!
The next afternoon, our class went to the Science and Technology Festival. As soon as I got downstairs, I was shocked by the scene in front of me. The students were so crowded that it was difficult to squeeze in and have a look. On the playground, a huge model airplane flies in the sky with colorful ribbons, which attracts many curious eyes. Some scientific and technological works are a windmill turned by water, and water is used as power energy to drive the windmill, which is the first time I have seen it! Some scientific and technological works are a remote-controlled car, which runs happily in freedom. Some scientific and technological works are a robotic arm with a pen in the middle. A classmate holds the remote control and presses a switch to make the robotic arm write words. Among them, I am most interested in a paper shell covered with needles. I put a balloon on it. As soon as I put it down, we ran away, for fear of the sound of balloon explosion! But looking back, the balloon was safe and intact. It turned out to be the principle of air, which really made people sit up and take notice!
The bell rang for class, and we left step by step. This science and technology festival really opened my eyes and feasted my eyes. I wish every science and technology festival was so interesting! Primary school science and technology festival composition 4 words 6
People have joys and sorrows, and the moon is full of rain and shine. Today, I am extremely happy! Happy, because I was interviewed again today!
today is the annual science and technology festival in our school. There are colorful science fiction painting, various small productions, lively and interesting scientific compositions, and live paintings. Of course, I also joined the ranks of live paintings.
in the afternoon, I started my painting. I know exactly 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 and continued painting. After a few minutes, I finished painting.
The 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 I won't have the problem of saying something wrong. What should I say and what shouldn't I say? I looked nervous, but I finally managed to answer their questions with a smile and broke out in sweat. I jumped three feet high with joy. Great, the sweat on my head disappeared instantly, and my face was full of joy. However, I will continue to work hard.
I was interviewed today. Primary school science and technology festival composition 4 words 7
We have ushered in the annual sports science and technology festival in our school. 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 selected by my teacher as a 2-meter runner, and there are three people in a class. I am one of them. This time, the 2-meter runners are all elites from all classes. 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 strive for the class.
At last, the annual sports festival began, and everyone was very excited. I was assigned to the third round of tension. I was very nervous, trembling all over, and under great pressure. The challenge was that the elite competition was ready to start, and a gun was fired, "Bang!" Everyone started at the fastest speed and shot out like an arrow. I tried my best to overtake the two in the second corner, when I heard the cheers and cheers of the class in my ear. The whole room is boiling, and I am more motivated.
I glanced at the side with my eyes, and my opponent was not far away. At this time, my opponent was as hard as me, and his face was blue and his lips were white. As long as I try harder, I can surpass him. So I secretly cheer for myself in my heart! Overtaking three people in the third corner, I felt that 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 with my classmates. There was a loud refueling sound in my ear again. "Ye Guo, come on!" "Ye Guo, come on!" When I grind my teeth, I use my strength to suck milk. Finally, I finished the game with the third place at the finish line. At the moment I stood at the finish line, I sat down on the ground, surrounded by my classmates, still praising me.
I know that 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. Primary school science and technology festival composition 4 words 8
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 crowded among dozens of classmates on the basketball court. Everyone was holding their beloved four-wheel drive and tickets, and lined up in a long line around the curved track, always ready for the game to start. 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. The car reached the corner, and his eyes widened with nervousness. Fortunately, the car turned the corner smoothly, and he took a long breath. When the race was over and the car was returned to him, he jumped for joy. It's the turn of Shao's blue bike in our class. His car is equipped with a high-power motor, which is full of energy like a blue BMW. It's very easy to climb high slopes. Almost past the corner, BMW is still rushing, and we are all sweating for him. As soon as I blinked, I heard a bang, and the BMW turned over and fell to the ground. There was a sigh around.
The "Super Bubble" game on the playground has also attracted many students. Under the sunlight, the big bubbles show colorful light, which is very interesting. On the field of drones and rubber-band powered aircraft, there are also cheers and exclamations.
our science and technology festival is so happy and interesting! Primary school science and technology festival composition 4 words 9
In a morning when everything is reviving and spring is shining. I walked to school with my schoolbag on my back and relaxed steps. The sun is high in the sky. It's warm and refreshing. I'm very excited. That's because the annual Science and Technology Festival of our school is about to open today.
In the weekly class, I heard on the radio that the content of this year's Science and Technology Festival is to plant flowers and plants in each class, and also mobilize students to take waste newspapers from home to the class, and collect the money they sell to buy all kinds of flowers and plants, so as to cultivate students' sentiment with their rich knowledge about flowers and plants. As soon as I entered the classroom, a mountain of newspapers appeared in front of me. The newspaper that was originally handed in next Monday was unexpectedly enthusiastic about the students' participation in the Science and Technology Festival. Within a few days, the newspapers in our class sold the whole 4 yuan and bought seven pots of flowers, but after all, our flowers were too few. My classmates and I also brought our own flowers, and some people brought peppers, strawberries, redwood trees and roses ...
In the classroom. In this science and technology festival, natural science also has the task of planting. Teacher Du asked us to plant onions in groups, and the students were ecstatic. It didn't take long for our onions to grow tender roots, and 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 and plants. This year's science and technology festival is coming to an end, and everyone is looking forward to the next science and technology festival!

Today, our school held 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 begins with a Newton's disk competition. In the cheers of the students, the Newton's wheel of the players turned very fast and buzzed. After a while, the game was over, and my heart was pounding. Did we win? No idea? I heard that it will be a long time before the results of the competition are broadcast.
it's my turn to attend next.
