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 nowadays。More and more teachers and parents are beginning to pay attention to cultivating children's scientific literacy from an early age，使孩子从one开始便养成良good的性格和行为习惯。亲子互动手工可以提high亲子陪伴的质量，Improve parent-child relationships，我们和孩子在one起的时光，No mobile phone、ipad、Television，Only joy，Interaction and communication。 It can cultivate children's ability to solve problems by themselves when they encounter problems，Children should first see and experience the solution by themselves，Because this is how my parents and teachers solve problems while doing handicrafts。 It can develop children's imagination，In a child's world，Cars can fly in the sky、The sun can be green...... Play handicraftsDIYChildren's hands-on ability can be cultivated by using different tools，The child's little hands got sufficient exercise。Brush、Pigment、Scissors、Hot-melt gun、Glue.....，Dare to try any tool，也在one定程度上开发着不同的技能。 Boosting children's self-confidence during the process of handicrafts，我们one起尝试万般可能，Have experienced many failures，But it always succeeds，在one定程度上增强了他的自信心。 Cultivate children's concentration when they are exploring various tools and handicrafts，He is very focused，If there is no external disturbance，他可以one直探索下去。
Experimental purpose：Entertain through games，Let children learn more scientific knowledge and develop their own hands-on abilities。
Principle application：串联电路
定义:The electrical appliances are connected to the circuit end to end in sequence。Parallel circuit：Parallel circuit是使在构成并联的电路元件间Current有one条以上的相互独立通路.
Experimental cognition：Parallel circuit只有one条路径,任何one处开路都会出现开路。
Knowledge expansion：Rhyming mnemonic：End to end connected，串成one串。The head and tail are connected，Connect them one by one in sequence。
Current：In a series circuit, the current is equal at all points。
Voltage：The total voltage in a series circuit is equal to the sum of the voltages of each part of the circuit。
Resistance：串联电路中总Resistance等于各部分电路Resistance之和。
Knowledge extension：one、The characteristics of series circuits
1、In a series circuit, the current is equal at all points。
2、The total voltage in a series circuit is equal to the sum of the voltages of each part of the circuit。
3、串联电路中总Resistance等于各部分电路Resistance之和。
4、串联电路中各部分电路两端Voltage与其Resistance成正比。
two、Parallel circuit的特点
1、In a parallel circuit, the total current is equal to the sum of the currents in each branch。
2、In a parallel circuit, the voltages across each branch are equal。
3、The reciprocal of the total resistance of a parallel circuit is equal to the sum of the reciprocals of the resistances of each branch。
4、In a parallel circuit，The current flowing through each branch is inversely proportional to its resistance。
Safety Warning：All the accessories in this product are special equipment for student experiments and production，Please ensure safety under the supervision and guidance of teachers and parents Use it all below！All products are prohibited from consumption！Not suitable for children under three years old，Do not press near the fire source。If used Please check whether the circuit is unobstructed before assembling the battery、Whether the accessories on the circuit are complete，Whether each contact is good or not good，On the battery+It is the positive pole、-It is the negative pole，组装过程中注意If usedGlue不要弄到眼睛和皮肤上。
