Junior high school students' scientific and technological innovation gizmos

When class is over, it is found that few people will turn off the lights after school, and the students' seats are scattered, so we want to invent a control device, which can automatically switch on and off the number of lighting lamps according to the number of students in the classroom, so as to achieve the purpose of automatic energy saving. In this way, we developed an energy-saving controller for classroom lighting. This was told by the students of the Creation and Invention Group of Shanghai Road Primary School. This invention won an award in the 7th Shell Beauty Action held recently. There is a counter at the door of the energy-saving controller. One person enters and one person adds. For example, four people turn on a light through computer programming, so that the first light is turned on from the first person after entering the door, and then the second light is turned on after the four people are satisfied, so that students can sit together, which is suitable for university study rooms or extracurricular classes and realizes energy-saving control. Fu Jun, the teacher in charge of the invention group, told the reporter: "Our school participates in the Science and Technology Innovation Competition and the Shell Beautiful Environment Action Award every year. When a student was outside class, he found that there were many empty seats with lights on every time, which consumed a lot of electricity, so he had the idea to change this situation. During the holiday, his parents who knew how to control electricity taught him a whole set of techniques, and his grandfather, a university teacher, was also teaching him. He sees the real thing, feels it, and then understands these programmed components faster. Finally, with the joint efforts of teachers, students and parents, the invention was successfully released. Although the student is now in junior high school, he is still persistent and interested in invention and innovation, and is still trying to make inventions. His current teacher also encourages him to try to invent the car ticket checking machine, which means that people can get on and off the bus, so that the tour guide can easily know how many people are on the bus, thus enhancing the motivation of students to study physics and other courses, and learning with interest every day makes learning very easy. " In fact, scientific and technological inventions don't have to be made by college students or professional inventors, and innovation is equally important for primary school students. What they are best at is "whimsy", and they can open their minds without any restrictions. The teacher encourages every student to broaden his mind, pay attention to the little things around him, and observe the problems encountered in study or life. This is probably the point of invention. Then, the teacher will let the students express their views, express their views or suggestions on this issue, and guide the students to look up some information online, discuss with their parents and learn more about the information. Even if some inventions have been published, we can further analyze and study according to the shortcomings or characteristics of the original inventions, develop new inventions, and recommend works to various competitions or activities. Teachers will apply for patents for the winning works to encourage students' creativity. In the interview, what Mr. Fu told reporters the most was to cultivate students' innovative ability from an early age. Invention is the most effective way to stimulate students' consciousness. Once Fu was on duty outside, a student saw her and told her at once that he had a new idea. This is not a passive question, but what the student said on his own initiative, which shows that he has a sense of innovation. The most important thing of invention and innovation is to let students know how to make inventions. First, they should find innovations, and then find difficulties and solutions. In addition, they should cultivate the ability to use their hands and brains, so that when they encounter difficulties in their future lives, they can help more people instead of hiding. "I usually tell them that in fact, everyone can have the opportunity to invent or invent, but those who fail to invent hide because of difficulties, and some people will find ways to solve the problem, and he may succeed. In this way, children's innovative consciousness will be cultivated and they will be brave in innovation in their future work. I believe that they can have this ability, become confident and let learning and invention promote each other. " Teacher Fu said meaningfully.
