Some 7th graders have been working on an electronics extension to their science class. The students are learning about circuit constuction on printed circuit boards using passive and active components. As well as acquiring precision soldering skills and learning how to read component identification markings, the project includes leaning about inductance, inductive coupling, semiconductor operation and the math that is used in conjunction with some of these devices.

When completed the students will have working metal detectors and an understanding of how the associated electronics functions.
