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: To enable children to learn more about scientific knowledge and their own ability to practice by means of game entertainment.

Principle Application: Aircraft rise by means of parallel thrust, and a good hand-thrown flight trajectory should be a beautiful arc. Many people mistakenly throw the aircraft into the air with a high angle of attack, which is actually very easy to stall and makes it fly further.

Experimental Cognition: The ascent of an aircraft is based on the Bernoulli Principle. The wings are designed with an arc on top and a flat or concave shape on the bottom, so when the wing moves forward, the airflow on top is faster than that on the bottom. According to the Bernoulli's Principle of fluid dynamics, the air below will exert a pressure on the air above, which is the lift of the wing, supporting the aircraft and allowing it to fly in the air.
Hand-thrown planes also rely on the basic principles of planes, but they provide thrust by throwing the plane forward with their hands.

Knowledge Expansion: According to the law of conservation of energy, energy cannot disappear nor be created from nothing; it can only be transformed from one form to another. In low-speed airflow, the energy involved in the conversion is only pressure energy and kinetic energy. Air of a certain mass has a certain pressure that can push objects to do work; the greater the pressure, the greater the pressure energy; air in motion has kinetic energy, and the greater the flow velocity, the greater the kinetic energy.

Knowledge extension: The airflow speed is only due to the action of the propeller on the air by the engine, and of course, from this analysis, energy is also conserved.

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.
