Project-Based Learning(Project-Based LearningProject-based learning is a teaching method that designs learning scenarios, which is a problem-oriented approach based on a student-centered education model that is grounded in the real world.Project-Based LearningThe teaching of this subject involves subjects such as mathematics, physics, technology, engineering, and design, etc., so the teaching content is actually a comprehensive curriculum around various problems. This requires students to solve problems through interdisciplinary and cross-field learning.

Students in order to successfully completeProject-Based LearningProjects require the integration of knowledge from various disciplines and life experiences, as well as cooperation with the team to solve various problems.

In this process, the behaviors of inquiry, communication, innovation, and collaboration exhibited by students are beyond the reach of traditional teaching models. It is precisely through these behaviors that the comprehensive quality of students is enhanced in all dimensions.

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:

Have you ever seen a scene where a mechanical arm works in a factory? Do you know how to press a well pump more efficiently? Today, let's build a mechanical arm to experience it.

Theoretical Analysis:

Knowledge point 1: Guide rail: The guide rail supports and guides the moving parts along a given trajectory and stroke, making straight or curved recurrent movements under the action of the support point. The guide rail is composed of two relative moving parts, one of which is fixed to the frame and is called the static track. The fixed plate behind the crocodile hand is the static track of this mechanical hand. The other part moves on the static track and is called the dynamic track. The part pulled by the hand is the dynamic track of this system.
Knowledge point 2: Linkage Mechanism: In this experiment, a planar linkage mechanism is used. Its characteristic is that there is a component that moves in a plane, which is called a linkage. The linkage mechanism is also known as a low-pair mechanism. The link plate connecting the crocodile's mouth and the hand pull part is the linkage. This set of devices also uses the elastic potential energy of rubber bands, allowing the crocodile's mouth to automatically open when the hand is released.

Safety Warning:

All the accessories in this product are specially designed for student experiments. Please use them under the supervision of teachers and parents to ensure safety! Do not consume any of the products! They are not suitable for children under three years of age. Do not approach fire sources. Before assembling any batteries, please check if the circuit is clear, all parts of the circuit are complete, and all contacts are good. The + on the battery is the positive pole, and - is the negative pole. Be careful during the assembly process, and if glue is used, do not get it in your eyes or on your skin.
