A preliminary study on the scientific and technological invention activities of primary school students

Invention is a new product that needs to be creatively designed and manufactured according to the inconvenient, inconvenient and unsatisfactory things encountered in daily life, study or labor by using scientific knowledge and laws. This kind of activity makes students use their hands and brains, which can easily stimulate students' interest in scientific practice, develop their potential and cultivate their practical ability and creative spirit.

First, raise the issue of scientific and technological innovation.

In the process of scientific and technological education activities, students are the main body of the activities. They use the cultural knowledge and technology learned from textbooks and other ways to explore and experiment like scientists and gain creative knowledge. In scientific and technological innovation activities, under the guidance of teachers, find problems, find information, make plans, practice, accumulate data in experiments, and analyze data in research until you write scientific papers or create valuable scientific and technological works. Every time students complete a scientific research project, they go through a complete scientific research process, so that they can learn certain scientific research methods and improve their thinking ability in the process of solving problems in real life, study and work.

In scientific and technological innovation activities, students put forward some research questions or research methods, and teachers should give affirmation and active guidance. Our school is a rural school, and there are many flies in students' homes in summer. Hu found problems when killing flies: although flies can be killed with a fly swatter, it will leave dirty internal organs of dead flies, which is very unsanitary; If you use sticky fly paper, just wait for the fly? A trap? Can't take the initiative to attack, the effect is not good. Under the guidance of the teacher, from the study of fly swatter to the design and manufacture of sanitary fly killing bags. The sanitary fly killing bag can not only kill flies that can't fly, but also catch flies flying in the air; Be a fly? A trap? . This little invention won the second prize in the 22nd Jiaxing Youth Science and Technology Innovation Competition.

The school library is the second classroom for students. After students borrow books, their library cards are kept in the library. When students return books to the library, it is not easy for the librarian to find the library card of the returning students in the library card of a class. There are many people who come to return books and borrow books, and students have to wait in long lines. To this end, a pair of siblings Guo Ying? Guo used his brain and thought of many ways. After repeated attempts, hands-on practice and continuous improvement, each improvement took a step forward and was finally designed and produced? Looking for a convenient library card. This little invention won the first prize in the 23rd Zhejiang Youth Science and Technology Innovation Competition.

Second, explore independent innovation in science and technology.

Independent innovation is the training goal of quality education and an important way for students to explore independent innovation in science and technology. In the practice of science and technology education, in order to develop students' personality, stimulate students' own creation and promote the development of creativity, students must be allowed to design boldly, break through the original knowledge circle, break away from convention and produce new ideas. Especially for those innovative and original aspects, even a little spark should be affirmed and encouraged, so as to enhance students' self-confidence and enthusiasm and further develop their creativity.

For example, Zhu Yichao found that many people like to use disposable cups, especially disposable cups, to entertain guests, and guests also like to use disposable cups to drink water and tea, which is considered clean and hygienic. But there is a * * * problem in disposable cups at present. The cups in a bag of disposable cups are exactly the same. In crowded occasions, after the cups are released, it is often because you can't recognize the cups you have drunk, and then use new cups, which causes serious waste and pollutes the environment.

How to solve this problem and reduce the waste in disposable cups? Zhu Yichao studied it, thought of many methods, and finally designed it: numbered disposable cups? . For numbered disposable cups, put a bag of disposable cups, print different numbers on each cup: 1, 2, 3, and then write on the cups? Mark the cup well, and then drink it and find that the use of the cup is reduced, and environmental protection comes first? In that case.

Use simple numbers to distinguish disposable cups, to avoid people using more than two cups on one occasion, to reduce the use of disposable cups, and to reduce? White pollution? Enhance environmental awareness and carry forward the fine tradition of thrift. This? Disposable cups with numbers? The invention won the second prize in the 23rd Jiaxing Youth Science and Technology Innovation Competition.

Third, practice scientific and technological production activities.

To cultivate students' independent innovation ability, teachers must renew their educational concepts, change their educational viewpoints, firmly establish a student-oriented thinking, strive to create a learning atmosphere in which students actively seek knowledge, fully tap students' innovative potential, stimulate students' innovative thinking, boldly let students explore independently, and be masters of scientific and technological innovation.

For example, ship model activities, after the ship model is completed, it is necessary to conduct a trial model. The trial of ship model is an important measure to adjust the stability, course, speed and voyage of ship model. However, the vast majority of schools have no water area for ship model trial activities, and there is no water area for student ship model activities on campus, which hinders the normal development of student ship model activities. In the past, the ship model activities in our school could only organize students to run to the pond outside the school for sea trials, which was time-consuming, unsafe and particularly dangerous.

During the ship model activity, Li Wei thought of a rectangular water tank, where students washed their rice bowls at noon. As long as the water hole is blocked, the ship model can be tested in the pool, which is convenient and safe.

Li Wei's ship model was tested in the pool, and the sailing direction of the ship model was found. When the front end of the bow is facing the pool wall, the bow swings to the left, the bow swings to the right, and the bow swings to the left. As long as the bow does not sway, the direction of the model ship will be accurate.

The sailing direction of the ship model has been solved. How to test the sailing speed? Li Wei thought of dynamometer when he was doing experiments in science class, and hooked the dynamometer at the tail of the ship model, which had great tension and fast sailing speed. By using dynamometer, the sailing speed of the test ship model is really good.

Practice has proved that the ship model tester can measure water tightness, stability, course, speed and voyage in the pool and obtain accurate data. This not only saves time, but also is very convenient and safe, and can be tested while doing, which greatly improves the work efficiency of developing ship models. Under my guidance, our school's ship model players participated in the competitions in Tongxiang, Jiaxing and Zhejiang, and achieved good results. We carry out ship model activities not only to win prizes, but also to cultivate students' innovative spirit, improve students' innovative ability and establish innovative ideas!

This little invention has solved the problem that there is no place to try the sea for the majority of ship model enthusiasts. This scientific paper "Research Report on Ship Model Test of Common Family Pool" won the first prize of Tongxiang Youth Science and Technology Innovation Competition.

Our ship model activities not only combine textbook knowledge, scientific and technological innovation, skills and skills, but also raise the harvest experience of this scientific and technological innovation activity to theory. Through students' own design activities, they will constantly explore new ideas, try new things, create new things, and enter their own ideal new realm.

In short, under the guidance of new ideas, it is our goal to carry out research on cultivating primary school students' scientific invention activities, promote primary school students to learn and apply scientific knowledge in family, campus, life and society, and give full play to each primary school student's respective potential and creativity.
