"Science and technology are the primary productive forces" is a basic principle of Marxism. With the development of modern science and technology, it plays an increasingly important role in economic and social development. In 1980s, Comrade Deng Xiaoping assessed the situation and was far-sighted, and further made a scientific conclusion that "science and technology are the primary productive forces", pointing out in time that science and technology education should start with dolls. Therefore, starting from dolls to carry out science and technology education is the foundation project for the development of the motherland in the 2/kloc-0 century. The nature in which human beings live is an inexhaustible treasure house of knowledge, which contains many mysterious secrets. Many phenomena in people's lives have their own reasons. Pupils often ask teachers some questions, answer their questions in time, and actively introduce the scientific truth of things around them to pupils, which is conducive to cultivating pupils' interest in science and technology and making them form a good habit of loving and using science from an early age. It is a lifelong benefit for a person and a century-long plan for our nation. There are animals, plants, mountains, water, air and celestial bodies around us, which constitute nature. Everything in nature exists objectively and is constantly changing. Therefore, our science teachers should combine science lessons with science and technology education in primary schools and guide primary school students from all aspects. At the same time, the primary school science class shoulders the heavy responsibility of children's scientific and technological enlightenment, and its educational significance is very significant. Through the teaching of science class, let children form the habit of learning science according to the correct cognitive law. Although the knowledge learned in science class is not much, the children have mastered the method of acquiring knowledge and got the golden key to open the treasure house of knowledge. The study of scientific knowledge is carried out through the analysis of scientific phenomena and practical activities, which can cultivate students' interest in exploring various scientific and technological problems. The cultivation of hobbies often has a far-reaching impact on the growth of a child. The success of many scientists often benefits from the scientific enlightenment in childhood. Therefore, science and technology education in primary schools should focus on basic knowledge and skills, start with daily trivia and common natural phenomena, and teach them those easy-to-understand scientific and technological knowledge, but also involve some simple modern science and technology. 1. Guiding students to observe experiments is to guide primary school students to investigate natural phenomena under natural conditions, which is the first step to understand natural phenomena. Only by correctly understanding natural phenomena can we study it correctly, and the purpose of studying it is to master its laws, which often requires experiments. The experiment is to guide primary school students to use scientific instruments and equipment to control or imitate natural phenomena, eliminate interference, highlight main factors and study natural laws under favorable conditions. Scientific observation and experiment are the basic ways to collect facts and gain perceptual experience, and are the practical basis for forming scientific concepts, understanding scientific laws and testing scientific theories. Through observation and experiment, the curiosity and interest of primary school students can be aroused. With interest, they will get to the bottom of puzzling natural phenomena, and then teachers should pay attention to inspiration and analysis. If you observe the partial solar eclipse, you can first inspire students to think: What is blocking the sun? Then we can guide students to analyze the causes of the eclipse and get inspiration from the causes of the eclipse. Secondly, let the students consider how the relative position of the three changes before and after the moon blocks the sun. In order to help students understand, we can make a simple instrument and conduct a simulation experiment. Second, guide students to understand the laws of nature. Inspired by the teacher, students think and analyze. At this time, the teacher can guide them to find out the laws of nature. These laws are scientific knowledge. For another example, after observing and analyzing the solar eclipse, the teacher can guide the students to draw a rule: when the sun, the moon and the earth are on the same line, and the moon is between the sun and the earth, an solar eclipse will occur. When the observation point is on the same straight line with the centers of the moon and the sun, a total solar eclipse will occur; When it is not in line, there will be a partial solar eclipse. In addition, the sun is imaged through a small hole or convex lens, which is the same as that of a candle, which is also the reason for the round spot under the tree in summer. In this way, it is actually repeating the development process of the history of scientific development, that is, the progress history of human understanding of nature and the development history of cognitive ability. The task of science and technology education is to create a good condition for children and give them a good education. Through the intervention of teachers, they can complete the evolutionary history of human cognition for thousands of years in a very short time. The significance of this kind of basic science education lies in that "the line is small, the meaning is far-reaching, and the shallowness is deep." Thirdly, it needs creative personality to motivate students to make inventions. In this creative personality, those who regard their hands as equally important as their brains are often very creative. This so-called "hand instead of brain thinking" character often greatly promotes creativity and inventiveness. Thinking by hand means emphasizing the originality of the mind and being diligent in hands-on practice. Many creative ideas may come to mind, but the intentional creator will let his hands practice it. The teaching of science in primary schools can take some production classes according to the content of teaching materials. Through production, students' practical ability and interest in science and technology can be cultivated, and their understanding of what they have learned can be deepened. If you do a "constellation simulation", display it with lights, and press the button, the constellation you are looking for will flash on the simulated "canopy". This production, it can not only make the difficult content into something visible and tangible, but also help the classroom atmosphere to be active and deepen students' understanding in the process of guiding students to make. In addition, there are biological specimens and various models. Through the production, students can not only learn the perceptual knowledge of natural phenomena, but also gain preliminary experimental skills and the ability to observe and analyze problems. Science and technology education is also education. Only from primary school can we understand science and technology as soon as possible. More importantly, we are interested in science and technology and have scientific consciousness. The purpose of primary school science and technology education is to cultivate primary school students' awareness and ability of science and technology and improve their scientific and technological literacy. Therefore, as a primary school science teacher, whether imparting knowledge or taking any form, we should focus on improving students' scientific literacy. Doing so is conducive to cultivating students' scientific attitude and spirit of seeking truth from facts and being brave in exploration, improving students' scientific and technological ability, acquiring more scientific and technological skills in continuing scientific and technological education and training in the future, and laying the foundation for becoming useful people to society and the motherland. Looking forward to the future, full of hope, competition and challenges. The state has determined the strategy of "rejuvenating the country through science and education", the essence of which is to really shift the whole national economic construction of our country to relying on scientific and technological progress and improving the quality of workers. Therefore, we must give priority to the development of education and improve the scientific, technological and cultural quality of the broad masses of workers; Give priority to the development of science and technology, rely on science and technology to revitalize our great Chinese nation and realize our great "Chinese dream."
