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 family relationships, and we spend time with our children, without mobile phones, iPads, or televisions, only joy, interaction, and communication. It can cultivate children's ability to solve problems 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 small 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 handcraft, we have tried everything possible, experienced many failures, but we always succeed, which to some extent enhances their self-confidence. Cultivating children's concentration when children are exploring 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: Gravity is the force exerted on an object by the attraction of the Earth, but it should not be considered as the attraction of the Earth to the object. This gravitational force, in addition to producing gravity, also provides the centripetal force required for the object to rotate with the Earth's rotation. The direction of gravity is vertically downward, perpendicular to the horizontal plane, unaffected by other forces of action, and is unrelated to the object's motion. On the other hand, the direction of universal gravity is always directed toward the center of the Earth.

Experimental Cognition: Small-scale toy creations, which can stimulate children's curiosity and are characterized by scientific and rational design, are gaining increasing favor among parents, becoming a helpful tool for parents to educate their children. These toys can cultivate children's cognitive abilities, observation skills, memory, understanding, and coordination of various body parts.

Knowledge Expansion: Any two objects in nature are attracted to each other, and the magnitude of the gravitational force is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. Knowledge Extension: The law of universal gravitation (Law of universal gravitation), [1] is a law that explains the force of attraction between objects. The law was published by Isaac Newton in 1687 in "Philosophiæ Naturalis Principia Mathematica." The content of the law is that any two mass points attract each other through a force along the direction of the center of gravity. The magnitude of the force is proportional to the product of their masses, inversely proportional to the square of their distance, and is independent of the chemical nature or physical state of the two objects and the medium material.

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 the age of three. Do not approach fire sources. Before assembling any batteries, please check if the circuit is in good condition, all parts are complete, and all contacts are good. Remember that the + sign on the battery is the positive terminal and the - sign is the negative terminal. Be careful during the assembly process, and if you use glue, do not get it in your eyes or on your skin.
