The Science and Technology Festival was originally named Science, Technology, Culture and Art Festival. Science and technology is the crystallization of human wisdom, and it is also a powerful weapon for human beings to understand and transform the world. Turning over the history of scientific and technological development, we can also see a history of human civilization: from eating and sleeping of apes to interstellar travel of modern people; From ancient beacon communication to the present Internet; From ancient times to today, the full use of new energy, every progress of mankind has benefited from the exploration of the unknown world and the mastery of science and technology. Nowadays, technology has been integrated into life and enriched it. It brings people the convenience of material life and the joy of spiritual life. It can be said that human beings have created science and technology, and science and technology have also perfected human beings. Human beings and technology are interdependent.
Article 1: Science and Technology Festival
Time, like running water, flows far away and never returns. It's the annual science and technology festival again. From April 20th, the 22nd Science and Technology Festival held by our school began.
Monday: Ice necklace. The afternoon self-study has finally arrived, and the classroom is boiling. Let's discuss it together. At this moment, Teacher Yu came in and said, "Quiet!" When the classroom was quiet, Mr. Yu stepped onto the platform and said, "Now, please bring up the washbasin for the No.2 student in each group and get the ice and salt. After receiving it, you can start making ice necklaces! " After I went to get the materials, I worked with the members of our group. Feng Yongjie went it alone, Pingchuan also went it alone, and I cooperated with Zhou Zhou. I took out the rope, and Zhou Zhou put some ordinary ice cubes of different sizes under it. I asked for a colored ice cube and put it in the middle. Then, we pressed the rope tightly on the ice, sprinkled some salt, and finally, waited for a while. As time went by, Zhou Zhou and I watched it take shape, so we gently picked up the ice necklace and said, "Bang! Bang! Bang! Hey! " The ice fell. I closed my eyes and didn't want to see the ice necklace fall to the ground. "Zhu, Zhu, look!" Zhou Zhou said in surprise. I opened my eyes and looked, "Ah, it's beautiful!" I cried too. It turns out that there are three pieces of ice in turn on the ice necklace, and the middle one is still colored. However, this time, it was a long contest, so I still didn't win the prize.
In addition to the ice necklace on Monday, the Science and Technology Festival also includes: playing cards on Tuesday, plastic bottles sprayed with water on Wednesday, waste utilization on Thursday and bubble blowing competition on Friday.
Science and technology festival activities not only make us learn new knowledge, but also make us feel so happy!
Chapter II: Colorful Science and Technology Festival
This week, our school held a science and technology festival, which added a touch of gorgeous color to learning. The teachers and students in the class have all gone out, and there are three parents.
Also finish the game of science and technology festival with us.
Blowing bubbles, drawing science fiction painting, waste innovation, lovely ice necklaces or water-spraying plastic bottles are all inferior to the nervous and happy mood of playing cards.
First, the teacher told us how to play poker: "In the third class, I will familiarize you with poker, and then the official game will be 2+ 1. Time is only 30 minutes! " At Mr. Tong's order, we did as Mr. Tong asked. The first time, I still didn't understand, so everyone broke the cards and misled our group to go up.
Into the bottomless pit. We didn't get taller once. The second time, sum up experience, determine the plan, and climb up step by step. Zhong Qidong took the card and put his hand gently on it. Everyone held their breath and stared at Zhong Qidong's hand intently, for fear that the card would be dropped accidentally, and all the good wishes in front of them were in vain. Zhong Qidong also slowly climbed up, maintained a balance, and did not dare to leave the atmosphere. Teacher Tong saw it and quickly took a ruler and measured it: 86 cm. All the cards are only 86 cm, and the other team will definitely surpass us. So I said, "Are we using too many cards in the chassis?" "Yes, let's draw some cards from the chassis." "OK, but be careful!" I repeatedly reminded that Zhong Qidong carefully picked a few cards from below and put them on. Teacher Tong came over and measured it gently: 93 cm. Zhong Qidong didn't seem satisfied, so he took out his card and pondered it. After a while, Zhong Qidong posted the new method and asked Teacher Tong to test it. Teacher Tong looked intently and said, "Ah! My ruler is not enough! " A parent came to help and finally measured the length:1.5cm. We cheered: "We won the first place." Other groups are not to be outdone, and soon the second and third place will be born. Everyone is so happy that I don't know how to describe it.
