The purpose of this assessment probe is to elicit students’ ideas about complete circuits involving lightbulbs. It reveals whether students recognize the pathway of electricity in a complete circuit, including its path through a lightbulb, in order to light a bulb using only one strip of wire and a battery. “Batteries and bulbs” is a common instructional topic found in elementary school curriculum to help students acquire skills of inquiry, while learning what a complete circuit is and about the lightbulb. Middle school students build a variety of different circuits to trace the path of electricity and are able to understand why the lightbulb is designed the way it is in order to build a circuit. High school students have begun the study of particles smaller than atoms and their study may begin to link particles such as electrons to the notion of charge and to ideas of current and electric circuits. Teacher notes, standards, assessment, and references are provided. This book selection also includes the Table of Contents, Dedication, Preface, Introduction, and Index.
