PBL(Project-Based Learning)Project-based learning is a problem-oriented teaching approach that designs learning scenarios and is a student-centered educational method based on the real world.PBLThe teaching involves subjects such as mathematics, physics, technology, engineering, and design. Therefore, the content is actually a comprehensive course organized around various problems. This requires students to solve problems through interdisciplinary and cross-field learning.

Students in order to successfully completePBLFor this project, it is necessary to integrate knowledge from various disciplines and personal life experiences, and work collaboratively with the team to address various issues.

In this process, the activities such as exploration, communication, innovation, and collaboration carried out by students are beyond the reach of traditional teaching methods. It is through these activities that the overall quality of the students is improved in all aspects.

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 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 different tools and crafts, they remain very focused; without external distractions, they can continue exploring indefinitely.

Experimental Objectives:

Do you have such a robot vacuum at home, little one? Do you know how this toy moves? Today, I’ll reveal the secret by creating a cute robot vacuum!

Principle Analysis:
Knowledge Point 1: Centrifugal Force: The motor at the bottom drives an eccentric wheel during rotation. The eccentric wheel moves in a circular path around the axis of the motor, with its rotation moving away from the center of the motor shaft, thereby generating centrifugal force. This force is transmitted to the robot. The robot continuously vibrates up and down. The bristles on the brush bar act like many legs for a vacuum cleaner. As the brush bar bends and stretches repeatedly during movement, the robot can move.
