The PhET: Circuit Construction Kit DC Activity Guide is used along with the free *Next Generation PhET Simulation “Circuit Construction Kit DC”. Students will discover the nature of direct current by building electrical circuits with batteries, wires, switches, bulbs, resistors, fuses, and other electrical components. In particular, students will learn about:simple circuitsopen and closed circuitsinsulators and conductorsmeasuring voltage and current with instruments (voltmeter and ammeter)the m
