Abstract: Science and technology is an important support for the development of national economy. In the overall quality structure of primary and secondary schools,science and technology education is an important way to implement quality education. By strengthening science and technology education in primary and secondary schools,youth science and technology awareness and quality can be strengthened,so as to promote the implementation of quality education. Taking the experiment of using sensors to measure the trajectory of flat throwing motion in physics teaching as an example,this paper explains the purpose and importance of science and technology education and the gains of teenagers in science and technology education.

Key words: science and technology innovation, science and technology education, sensor, trajectory method, flat throwing motion
