Preface

Today, with an increasing emphasis on children's education, scientific enlightenment education has gradually become an important topic pursued and explored in the field of education. More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age, enabling children to develop good personality and behavioral habits from the very beginning. Parent-child interactive handicrafts can enhance the quality of parent-child companionship and improve the parent-child relationship. The time we spend with our children, there are no mobile phones, ipads or TVS, only joy, interaction and communication. It can cultivate children's ability to solve problems by themselves. When encountering problems, children should first observe and experience them to solve them, because this is how parents and teachers solve problems during the process of doing handicrafts. 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 handicrafts can cultivate children's hands-on ability. By using different tools, children's little hands get sufficient exercise. Brushes, paints, scissors, hot melt gun, glue..... They are willing to try any tool and, to a certain extent, develop different skills. During the process of handicrafts, we tried every possible way together, experienced many failures, but always succeeded, which to a certain extent enhanced his self-confidence. Cultivating children's concentration: When children are exploring various tools and handicrafts, they are very focused. If there is no external disturbance, they can keep exploring.

The purpose of the experiment is to enable children to acquire more scientific knowledge and develop their hands-on abilities through game entertainment.

Principle application: Series circuit
Definition: Electrical appliances are connected in a circuit end to end in sequence. Parallel circuit: A parallel circuit is one that provides more than one independent path for current between the circuit components that form a parallel connection.

Experimental cognition: In a parallel circuit, there is only one path. Any open circuit at any point will result in an open circuit.

Knowledge Expansion: Linking Mnemonic: Connect the beginning and the end to form a string. Connect the beginning and the end, and link them one by one in sequence.

Current: In a series circuit, the current is equal at all points.

Voltage: In a series circuit, the total voltage is equal to the sum of the voltages of each part of the circuit.

Resistance: In a series circuit, the total resistance is equal to the sum of the resistances of all its components.

Knowledge Extension: I. Characteristics of Series Circuits

In a series circuit, the current is equal at all points.

In a series circuit, the total voltage is equal to the sum of the voltages of each part of the circuit.

In a series circuit, the total resistance is equal to the sum of the resistances of each part of the circuit.

In a series circuit, the voltage across each part of the circuit is directly proportional to its resistance.

Ii. Characteristics of Parallel Circuits

In a parallel circuit, the total current is equal to the sum of the currents in each branch.

In a parallel circuit, the voltages across each branch are equal.

The reciprocal of the total resistance of a parallel circuit is equal to the sum of the reciprocals of the resistances of each branch.

In a parallel circuit, the current flowing through each branch is inversely proportional to its resistance.

Safety Warning: The accessories inside this product are all dedicated equipment for student experiments and production. Please use it under the supervision and guidance of teachers and parents to ensure safety! All products are prohibited from consumption! Not suitable for children under three years old. Do not press near fire sources. Before assembling the battery, please check whether the circuit is unobstructed, whether the accessories on the circuit are complete, and whether all the contacts are in good contact. On the battery, + is the positive terminal and - is the negative terminal. During the assembly process, be careful not to get glue on your eyes or skin if it is used.
