preface:

with more and more emphasis on children's education, scientific enlightenment education has gradually become an important topic in the field of education. more and more teachers and parents begin to pay attention to cultivating children's scientific literacy from an early age, so that children can develop good character and behavior habits from the beginning. parent-child interaction manual can improve the quality of parent-child companionship and parent-child relationship. we have no mobile phone, ipad, tv, only joy, interaction and communication when we spend time with our children. it can cultivate children's ability to solve problems by themselves. children should first see their own experience to solve problems, because this is how parents and teachers solve problems in the process of manual work. it can develop children's imagination. in children's world, cars can fly in the sky and the sun can be green to play manual diy, which can cultivate children's practical ability by using different tools, the child's little hands are fully active. brush, paint, scissors, hot melt grab, glue, any tool dare to try, but also to a certain extent, develop different skills. improving children's self-confidence in the process of manual work, we can try it together and experience many failures, but we can always succeed, which to some extent enhances his self-confidence. cultivate children's concentration when children are very focused in the process of exploring various tools and handwork. if there is no external disturbance, he can continue to explore.

objective: to train children's ability to solve problems by themselves through experiments.

principle application: rocket launch is a huge and complicated project, and its basic operation principle is reverse thrust. using this principle, i made a small rocket without gunpowder.

experimental cognition: thrust generally refers to the airflow emitted by thrust device and engine.

knowledge expansion: reverse thrust is the equipment of modern large jet aircraft, which is located in the engine of the aircraft. the reverse thrust device is a device that can make the aircraft engine that injects airflow backward instead of forward. when the device is started, the engine makes the air flow through the small air outlet on the side of the engine by changing the air flow outflow channel and blocking the normal air outlet. the device starts immediately when the plane lands, which can make the large passenger plane stop as soon as possible when landing on a shorter runway or in harsh environment such as rainy days, thus greatly improving the safety of the passenger plane.

knowledge extension: the purpose of reverse thrust is to shorten the distance of aircraft landing and sliding, and to make necessary maneuver flight movements, it is often necessary to adopt corresponding deceleration.
