In the Discovering Electrical Systems unit, students get the chance to look inside some of the electrical devices they use every day and identify the various components that they find. Throughout the unit, they investigate how some of these components function in circuits. Students keep an inventory of all the electrical components that they investigate, including their schematic symbol, what they do in the circuit, and a drawing of each. Students build simple circuits into which they install each new component to get a first-hand account of how it functions. Students experiment with resistors, capacitors, diodes, and different gauges of wire. Before they move on to study different kinds of electrical systems, students must identify which component is inside each of four mystery boxes by connecting each to the circuit, observing the effect, and applying what they know about each component.
