Preface:

In today's society, where children's education is increasingly valued, scientific enlightenment education has gradually become an important topic in the field of education, which is pursued and explored. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good personalities and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child companionship, improve the relationship between parents and children, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate the ability of children to solve problems by themselves. When children encounter problems, they should first see and experience the solution themselves, because parents and teachers solve problems in the process of doing crafts. It can develop children's imagination. In children's world, cars can fly in the sky, and the sun can be green. Playing with DIY crafts can cultivate children's practical ability by using different tools, which fully exercises children's little hands. Brushes, paints, scissors, hot-melt guns, glue"Children are brave to try any tools and to some extent, they are developing different skills. Improving children's self-confidence in the process of handcrafts, we try everything possible together, experience many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children explore various tools and handcrafts, they are very focused, and if there is no external disturbance, they can continue to explore.

Experimental Purpose:

A DIY clock is composed of a movement, a dial, and hands, etc. The movement is powered by a battery, and the quartz crystal in the movement will produce regular vibrations. After amplification and frequency division by an integrated circuit, it drives a set of precision gear groups to rotate. By properly configuring the transmission ratios between the gears, the clock completes the timing function. This watch has features such as simple assembly, accurate timekeeping, and long service life.

Principle Application:

Human beings have had a superficial awareness of time from the beginning, to defining and calculating time on their own, and now to utilizing time. The history of truly assigning time to clocks only began to slowly develop in the 14th century. Narrowly counting the century-long journey of clocks, it has not only experienced the evolution from bell towers to standing clocks, but also the gradual replacement of pocket watches by mechanical watches, and the unprecedented crisis brought to mechanical watches by quartz and electronic watches. Can you think of any other timekeeping tools in history?

Children's Positioning Smart Watch:

As the main form of wearable devices, smart watches should have one or more functions such as reminders, navigation, calibration, monitoring, and interaction, in addition to indicating the time.

The Great Bell of China:
The initial water-driven astronomical observatory was a device that combined the Huin instrument, the Huin model, and a mechanical timekeeper. It used water power as its source of energy and had a scientific escapement mechanism. It was about 12 meters high and 7 meters wide, showing its size. Later, this giant clock
Destroyed by the humiliation of Jin Dynasty's invasion during the Song Dynasty's Jingkang Incident.
After the goods were transported back to their capital, there were parts along the way.
Damaged and unable to be repaired, this giant clock.
abandoned
