High school students' science and technology innovation competition project is in a hurry.

I participated in a national innovation competition for middle school students, and I have some experience to tell you. We have no say in pure theoretical physics, mathematics and computers because our knowledge is too limited. Our design ideas should tend to apply physics and computers. You can rule out computers, because the innovation of computers lies only in software (hardware we can't do), that is, programming. High school students don't understand basic language, java language and so on. So we must apply physics. Once you have determined this broad range, you can begin to conceive.

Applied physics is closely related to life. It uses physical knowledge to solve some difficulties and inconveniences in people's lives. For example, a floor machine that can move around and sweep the table tennis scattered on the ground into a grid, an electric wheelchair, an automatic mahjong machine and so on. Through the above, have you thought of making an automatic moving vacuum cleaner, an electric cradle and an automatic chess machine? By analogy, you can have many ideas in a short time.

From a more practical point of view, considering that high school students are short of time and have nowhere to find information, we can do something very simple. For example, a shovel selling special goods, a model with a rain-proof device outside the bus door after opening, a model of a wall speaker, and a device that can inflate the tires by turning on the switch after stepping on the bicycle wheel. ...

In short, innovation comes from life. Five people won the national first prize in my competition. One is the discovery of new biological species, the other is the invention of a new method to form 3D images, and the other is the discovery that honeycomb is not hexagonal (this is a bit nonsense), all of which are like a fantasy. There is also a drunk driving test device (physical chemistry, in fact, the blueprint is the after-school experiment in the chemistry textbook, and this award is too mysterious), and the last one is a social research paper. You see, except for material reality, we are all irrelevant. It's good to take part in the innovation contest, but don't pay too much attention to the results. This thing often depends on your money and luck.
