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.

The purpose of the experiment: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle Application: A motor drives a sound cylinder with small protrusions to rotate uniformly. When the protrusions pass the sound
When playing the board sound, you can pluck the spring (first slowly lift it up, then suddenly drop it) to make the spring
Vibrate at the set vibration frequency and emit the set sound.

Experimental Cognition: The Role of Damping, Enabling a Simple Sound
Perform uniform rotation

Knowledge Expansion: The Soundboard of an Music Box
The pieces are cut from a flexible steel plate into uniformly long and short, but thin and thick, strips.
Made (thickness and thickness vary according to the set vibration frequency). A protrusion on the sound tube
It's like a note on a musical score.

Knowledge Extension: A music box usually completes a full rotation in a week with a standard mechanism.
Between 8-17 seconds, that's enough to cover the climax of a song.
Express it; of course, high-end music boxes usually take 30 seconds to 8 minutes.
Minutes between cycles!
