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.

The purpose of the experiment is to cultivate practical ability and enhance structural imagination.

Principle application: A compass needle can freely rotate under the action of the natural geomagnetic field and remains along the tangent direction of the magnetic meridian. The north pole of the compass needle points to the geographic North Pole, and this performance can be used to identify directions.

Experimental Cognition: The Earth is a large magnet. The Earth's two poles are located near the geographic South Pole and the geographic North Pole.

Knowledge Expansion: On the surface of the Earth, when magnetic objects can freely rotate, they will indicate the direction of the North and South due to the properties of magnetic repulsion between like poles and attraction between opposite poles.

Knowledge Extension: The compass, which was known as the southern pointer in ancient times, consists primarily of a magnetized needle mounted on a axis. The needle is free to rotate in response to the natural magnetic field and stays aligned along the meridian of the magnetic poles. The north pole of the magnetically oriented needle points to the geographic North Pole, making it possible to determine directions using this property.
