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 circular motion of the motor causes the diaphragm within the pump to make a reciprocating motion through mechanical devices, thereby compressing and stretching the air in the fixed volume of the pump chamber to form a vacuum (negative pressure). At the suction port of the pump, a pressure difference is created with the surrounding atmospheric pressure. Under the action of the pressure difference, the gas is pressed (sucked) into the pump chamber, and then discharged from the exhaust port.
Experimental cognition: water dispensers are filled with water by air pressure, and the internal water circulation is achieved through negative pressure. A water pump is a small appliance that controls the circuit by water pressure.

Knowledge Expansion: A water pump is a small electrical device that controls circuits using water pressure. It works by pumping water through a system of moving parts to create a pressure difference, which in turn controls the flow of electricity through a circuit.

Knowledge Extension: When using a household water heater, pressing the heating switch provides power to the 'Preservation' indicator light, which serves as a power-on indicator. At the same time, the power is divided into two paths: one forms the heating circuit, enabling the electric heating tube to power on and heat up; the other provides voltage to the 'Heating' indicator light, serving as a heating indicator. When the water in the heat tank is heated to the set temperature, the temperature controller contacts break, cutting off the power supply to the heating and heating indicator circuits. The 'Heating' indicator light goes out, and the electric heating tube stops heating. When the water temperature drops to the set temperature, the temperature controller contacts connect the power circuit, and the electric heating tube re-heats, thus continuously maintaining the water temperature between 85-95°C.

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.
