Preface:

In today’s era where more and more emphasis is placed on children’s education, scientific enlightenment education has gradually become an important topic in the field of education. More and more teachers and parents are focusing on developing children’s scientific literacy from an early age, enabling them to establish good character and behavioral habits from the beginning. Parent-child interactive crafts can improve the quality of parent-child time together, enhance parent-child relationships. The moments we spend with our children are free from phones, iPads, or televisions—only joy, interaction, and communication. It helps children develop the ability to solve problems on their own. When faced with challenges, children must first see, experience, and resolve them themselves, just as parents and teachers do during craft activities. It also stimulates children’s imagination—in their world, cars can fly in the sky, and the sun can be green... Playing with DIY crafts allows children to develop hands-on skills by using various tools, giving their hands ample opportunity to move. Pencils, paints, scissors, hot melt glue, tape—they all challenge children to try, and to some extent, help develop different skills. It boosts children’s confidence. During craft activities, we explore countless possibilities and experience many failures, but we always succeed, which in turn enhances their confidence. It helps cultivate children’s focus. As they explore various tools and crafts, they remain very focused; without external distractions, they can continue exploring indefinitely.

Experiment Objective: Through gaming and entertainment, help children learn more scientific knowledge and develop their hands-on skills.

Principle Application: Elevators use motors as the driving force, leveraging the deceleration and self-locking properties of worm gear sets to allow them to carry heavier objects. The self-locking structure of the worm gears ensures that the elevator car does not fall downward after the motor stops rotating.

Experimental Cognition: Scientific Principles: Worm gear transmission refers to a mechanism where a worm gear is used for deceleration rotation. When the reverse stroke is not self-locking, a worm gear can also be used for acceleration rotation. Worm gear transmission consists of

Composed of a worm and a gear, generally the worm acts as the active component. Worm and

Threads also come in right-hand and left-hand varieties, respectively known as left-handed worms.

Right-hand rotation worm.

Knowledge Expansion: The Burj Khalifa was originally named the Dubai Tower, also known as the Dubai Building

The Burj Dubai is a world-class skyscraper and man-made structure.

Knowledge Extension: An elevator is also known as a lift. It is a vertical transportation device and an essential transportation facility in high-rise buildings. It operates on electricity, pulling a car that can carry people or goods, and moves vertically along the rails within the building's shaft. The elevator generally consists of five parts: (1) the shaft and machine room; (2) the transmission part; (3) the lifting part and safety devices; (5) the control part.
