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: Children assemble their own educational toys, which can stimulate their innate desire for exploration and growth. It establishes a learning environment and creates a space for activities and exploration, helping children to maximize their potential. The right choice can create opportunities for learning for children, and its impact will last throughout their lives. When parents play with their children and provide appropriate guidance, they can help children complete the process of understanding knowledge, establishing relationships, recognizing rules, self-reliance, and establishing self-awareness during the fun of play.

Principle Application: By utilizing the elasticity of rubber bands, the elastic potential energy is converted into kinetic energy, which drives the fan blades to rotate, and the fan blades blow air backward to push the car forward.

Experimental cognition: The fan blade is inclined at a certain angle, cutting the gas backward to drive the car.

Knowledge Expansion: The blades of a fan are inclined at a certain angle, with an approach angle generally around 18°. When a fan rotates, the air does not rotate in sync with the blades due to inertia, but when the blades pass through the air, the inclined blades compel the air to move in the desired direction (not necessarily downwards; a range hood or ceiling-mounted exhaust fan can exhaust air upwards). Due to the airflow creating a negative pressure, air around the fan will be drawn in to form a stable airflow.

Knowledge Extension: Students can find their own materials to make a rubber band powered car without a fan blade.

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.
