The development of science skill is done by Integral Public Elementary School of Lukman Al Hakim Mataram. Students who are in grade VI are interested and active in teaching and learning process. Began to assemble series or parallel electric circuits.
"We want students to understand about the simple electrical circuit, be it series or parallel through practice," said Integral Elementary Principal Lukman Al Hakim Agus Adnan, yesterday (21/10).
In this practice, Adnan said, the teacher has prepared the necessary tools. Such as card board, battery, cable, small light bulb, transparent insulation, paper, and clamp. Before practice, the teacher first gave the theory through the demonstration method. Shows glimpses of electrical circuit drawings.
"The type of equipment introduced to the student. The results of this practice will be presented later, "said Agus.
Furthermore, from this practice can be known to students' understanding of electrical circuits. From this practice also known advantages and disadvantages of each type of electrical circuit. As the series electrical circuit losses are the flame of the light dims when one of the bulbs is removed.
"Conversely, the advantages of this type of circuit is none other than cable and cost savings," he said.
While the parallel electrical circuit is advantageous because when one bulb is removed, the other lights remain brightly illuminated. There are only drawbacks that require more wires and switches than series. While this practice is not only a highlighted result, it is also a process.
"Like building cooperation. Students must be united and share the same vision in cooperation, "he added.
