With the ever-changing development of the times, we are full of longing for science, and we hope that one day we can go to climb to the top of science. However, at a young age, I was also full of curiosity about science.
When I was a child, when others talked about science and technology, I always felt that it was so profound and boring, and that was the business of scientists, which did not seem to have much to do with children.
When we started science class in third grade, the teacher showed us all kinds of scientific problems in an easy-to-understand way, guided us to recognize the scientific mysteries of nature through observation, measurement and experimentation, and taught us to learn how to apply scientific principles to solve difficult problems in life. I remember once, I was playing ping-pong at home when I accidentally stepped on the ball, the original round ping-pong ball all of a sudden concave a piece, with what tools can not make it drum up. At this time, I remembered that in my science class, my teacher had introduced an experiment using the principle of heat expansion and cold contraction of objects, which might make the ping-pong ball bulge up. So I put the ball in a cup and poured hot water into it, only to hear a soft sound, the ping-pong ball bulged up and returned to its original form. This incident makes me realize that science and technology is so close to our lives, and since then I have gradually become y interested in science and technology!
The development of science and technology is elusive, from ancient papermaking to the current high-speed development. Newton, Einstein, Zu Chongzhi the name of this one to create a miracle, so that the development of science and technology to move forward at a rapid pace. This magical and fantastic, wonderful and real exhibition is the proof. Let us go to experience the science of the fantastic and wonderful, fly our dream of pursuing science!
Science and technology is all around us, happy life and a better future to rely on their own to create, students, let us from now on on the chest to build a moderately prosperous society in all aspects of the grand goal, from the little by little to start, and study, forging themselves into a piece of good steel, the construction of our society is more beautiful it!

Technology and our lives are really closely related, because we live in the embrace of science and technology every day, we are enjoying every day, science and technology to bring us the convenience and speed.
Technology makes people's shopping easier, nowadays the Internet has come into thousands of households, people are also more and more like online shopping, online shopping has become an inseparable part of people's lives, busy courier, the increasing number of bird boxes, and double eleven everyone buy buy buy passion, do not explain this.
Technology has made people's travel more convenient, more and more high-speed trains, railroads throughout the country, the endless flow of vehicles on the highway, as well as flying to and from the plane, all highlighting the modern society's convenient transportation, well-connected three-dimensional transportation links to the country's various geographic areas, promoting the development of China's economy, and convenient for people's lives.
Technology has made people's communication faster, through the smart phone we can not only call anytime, anywhere, but also video chat, you can see each other across oceans and thousands of miles away, you can not leave the house and know all the world's affairs.
The benefits of technology to our lives are too great to mention.
But while technology has brought convenience to people, it has also brought sorrow. The development of science and technology at the same time, some people are using science and technology means to violate the law and bring great harm to our happy life. For example, yesterday I read from the newspaper that some unlawful elements use food technology to make fake steak, which will affect people's health if they eat it. Also, I heard from my grandmother that some people use telephone, text message and internet frauds at the end of the year, causing people's property to suffer losses. These situations show the bad side that technology can also bring to our life, people can only use technology wisely to really create a happy life.
In short, we can't live without science and technology, and every one of us elementary school students should learn science from elementary school and use science and technology to make life better.

Spring wind whisked through the place, will always leave a piece of vitality; the autumn wind walked through the road, will always leave the joy of the harvest; rain and dew moisturized, is the fragrance of birds and flowers. So, students, let's think about it, science and technology drenched in, and what will be?
From the ancient drilling for fire to today's electronic lighter; from the ancient hiking to today's space travel; from the forties huge computer to today's sweeping the world's handheld computers, are not poured scientists all their life's work, they use knowledge and wisdom for science and technology technology and innovation injected into the infinite active energy. Qian Xuesen for the development of China's rocket and missile technology has made significant contributions, known as the "two bombs" Deng Jiaxian is the development of China's nuclear weapons, Yuan Longping is known as "the father of hybrid rice", their success rightfully comes from science and technology, science and technology also left the footprints of China. The company has left a trail of footprints that have witnessed China's success.
Today, we are sitting in a spacious and bright classroom, listening to the teachers funny and humorous teaching of scientific and technological knowledge, wandering in the sea of science, those worthy of exploration of scientific phenomena, unexpected scientific experiments, hands-on scientific and technological inventions will inspire us to fall in love with the enthusiasm of science, as long as we have a curiosity to explore and pursue the issue of curiosity, there is a spirit of hard work to study the spirit of the spirit of defiance of the difficulties, and there is a meticulous rigorous scientific attitude, I believe that all the points of view of the scientific community, the scientific community, and the scientific community, we will be able to learn from them. Serious scientific attitude, I believe that all the accumulation of little by little, will become our driving force to fly the boat of science and technology in the future. Students, let's start now, do a love of science with a heart, polish our childish but intelligent eyes to discover the science and technology around us, in the future, you or I, will certainly use today's learned skills to dress up our more colorful life!
"Youth dreaming of serving the country with science and technology," after the fourth
In this ever-changing era, everything is changing rapidly, such as: medical equipment, mobility scooter to make these rapid changes in the back of science and technology.
Whether the development of technology is a big disadvantage or a big advantage. Today, I will discuss this with you. The development of science and technology does bring a lot of benefits to human beings, the rapid improvement of medical technology, everyone's health is guaranteed. Cell phones have been invented to make it easier to communicate with people. Mobility scooters are becoming more and more advanced, enabling people to go where they want to go faster.
But behind the good things are many hidden worries. The rapid development of medical science and technology has accelerated the speed of virus mutation, so that human beings are more and more dependent on drugs, and perhaps in the near future the human race will die out in a plague. The invention of cell phone is counted as one of the most important inventions in the 20th century, but I don't know if you have noticed that due to the endless fun that cell phone can bring to you, you are now using cell phone for everything you do, and you are getting more and more estranged from your loved ones. And long time looking at the cell phone will also affect the eyesight, cell phone control in the travel there are serious security risks. Walking machine can bring great convenience to people, but if people no matter what place to go to use a walking machine, then, because of a long period of insufficient exercise leads to atrophy of the limbs, the physical quality will be more and more poor.
Technological development is too fast, people's personal safety is even more unprotected, the society of high-tech crimes occur frequently, the international _ IS organizations use the Internet, kidnapping, killing hostages, and creating a number of terrorist incidents. Due to excessive emissions of industrial waste gas, the formation of haze, to everyone's health to bring a lot of hidden danger
Technology will also bring the bad side of our lives, people only reasonable use of science and technology, in order to truly create a happy life. Technology is around us, happy life and a better future to rely on their own to create. Youth dreaming, science and technology to serve the country!
