This is a science education kit that allows for basic electrical circuit creation experiments, such as series connections (series circuits) and parallel connections (parallel circuits). You can easily replicate science experiments related to electricity for elementary and middle school students at home. Children can assemble it themselves and learn about electrical circuits while playing. It is ideal for children who like science and for elementary and middle school science electricity and electronic circuit experiments. It is also recommended as science and science education equipment for training institutions and schools.

* You can conduct "heat generation by electricity" experiments with the heating wires.
* With two types of miniature bulbs (2.5V and 3.8V), you can also conduct "miniature bulb brightness" experiments.
* Using clip-on wires, you can experiment with materials that conduct electricity well and those that do not.
* With a generous quantity of miniature bulbs, you can gain a deeper understanding of how they light up by disassembling them and observing their internal structure.
* If you purchase two sets, you can create more complex electrical circuits.

See and touch it right before your eyes! Children can assemble it without adult help and can thoroughly test experiments like the miniature bulb experiments they learned in school at home. By understanding the principles of electricity, children can develop a basic understanding of how to handle and interact with electricity, while correctly grasping its dangers and conveniences.

You can replicate electricity-related experiments. Learn about electrical circuits while having fun playing up close with the mechanisms of electricity and electronic circuits. It can also be conveniently used for independent science research projects on electricity. It is also recommended as a gift for elementary and middle school students who enjoy scientific research. Make your child happy!

>>>> If the power does not turn on, please first carefully check the circuit connections.
If the circuit is connected correctly but the power still does not turn on, please try switching the "+" and "-" on the miniature bulb socket.
Please also ensure that the batteries have sufficient charge.
If, after checking all of the above, the power still does not turn on, please contact customer service. We can arrange for an exchange or refund as per your request.
