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:

Four-leaf clover, also known as the lucky clover, is a symbol of happiness and health, and has a beautiful meaning. Children, do you know why this toy and this group of performances can stand upright? Today we will make a swaying four-leaf clover, let's understand its principle.

Theoretical Analysis:
Knowledge point 1: The change in center of gravity and stability: Objects with a structure that is lighter at the top and heavier at the bottom are more stable, which means the lower the center of gravity, the more stable it is. When a eggshell is filled with clay, the center of gravity is concentrated on the eggshell. When the clover is in a vertical state and is in balance, the distance between the center of gravity and the contact surface is small, that is, the center of gravity is low. When it tilts, the center of gravity rises. Under the action of gravity, the clover returns to the balanced position. Therefore, this state of balance is a stable balance. Therefore, no matter how the clover sways, it is always not toppled.
Knowledge point 2: Center of gravity transfer: For example, the experiment of "rolling on a cone" we saw in the science and technology museum is also based on this principle. Due to the shape of the cone and the shape of the tracks on both sides, its center of gravity falls, but it seems to rise. Rolling upward does not conform to the facts of life. But it is just an illusion. Seeing its essence, the center of gravity is still lowered, so the lower the center of gravity, the more stable it is. In order to increase the stability of the object in life, we often use to increase the weight at the bottom, such as the base of the fan, the microphone stand, the base of the umbrella, etc.

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.
