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: The law of conservation of energy, which is the first law of thermodynamics, states that the total energy of a closed system remains constant. It is one of the universal and fundamental laws of nature, generally expressed as: energy cannot be created or destroyed, it can only be transformed from one form to another, or transferred from one object to another, while the total amount of energy remains constant. From this, the pressure in the syringe pushes the other syringe through the hose, driving the connecting rod to move.

Experimental Cognition: Adding water to the syringe will make the digging opportunity more sensitive. The density of air and water, with water having a greater density.

Knowledge Expansion: Hydraulic systems are widely used in industrial and civilian applications due to their large transmission force, ease of transmission, and configuration. The actuating elements of hydraulic systems, such as hydraulic cylinders and hydraulic motors, convert the pressure energy of liquids into mechanical energy to achieve the required linear recurrent motion or rotary motion.

Knowledge Extension: 1. In a closed container, an 'ideal liquid' transfers the pressure applied to its surface to all directions at equal values.
2. The transmission of speed follows the principle of 'equal volume change'.
3. The pressure of a liquid is established by external loads;
4. Conservation of Energy;
5. Hydraulic Impact. In a hydraulic system, due to certain reasons, the liquid pressure can suddenly increase abruptly, generating high pressure peaks, which is known as hydraulic impact.

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.
