Elementary school students have been disassembling and assembling clocks for a while in a workmanship practice class. Pen ~ fun ~ Pavilion www.biquge.info Wen teacher led the primary school students to disassemble and assemble toys, now the toys are high technical level, there is a low, the size of the technical content is very different, in the existing toys with the addition of science and technology, toys are also divided into low intelligent toys and high intelligent toys.

Most of the low-intelligence toys are toys without a control system, such as cars, trains, airplanes------。 This kind of low-smart toy is a toy that will run when the battery is pressed and the power is turned off, and it is controlled without a control system.

High intelligent toys are remote control toys with control systems, and the level of intelligence of toys is also remote control cars, remote control trains, remote control monkey somersaults to remote control robots, remote control unmanned aircraft and so on

Highly intelligent toys can bring children into a world of high intelligence development research, and it plays a great role in developing children's intelligence. However, the control remote control system of the highly intelligent toy, its highly intelligent part is composed of electronic modules after the integration of electronic circuits, this module is very simple to disassemble and assemble, but the working principle of the control system is the principle of electronic circuits, which is difficult for primary school students to learn.

In the maker training class, the primary school students have a comprehensive understanding of mechanical power, the movement of gears of mechanical transmission, and simple electronic circuits.

A year is about to pass, and Mr. Wen is preparing to hold a year-end evaluation competition for maker training and workmanship internship on the fourth floor of the teaching building.

At 8:30 a.m. on December 20, a maker training disassembly and assembly toy debugging and application competition on the fourth floor of the teaching was about to start. There are four maker teams with two players in each team, and a total of eight team members are ready to compete.

On the examination platform sat President Qian, Wang Youcai, Wu Likong, and Professor Wang, Engineer Gao, and Master Ji, who were invited to attend the meeting.

The place on the fourth floor of the teaching is very large, the front of the rostrum is four toy disassembly tables, next to the disassembly and assembly table is a toy competition field with a red carpet of about 200 square meters, there are more than a dozen rows of small chairs around the playing field, and more than a dozen rows of large chairs are placed behind the small chairs, the small chairs are for primary school students to sit on, and the big chairs are for the parents of students to sit.
