## Light Bulb Anatomy - Questions

The Light Bulb Anatomy Concept Builder is comprised of 48 questions. The questions are divided into 18 different Question Groups. Questions in the same group are rather similar to one another. The Concept Builder is coded to select at random a question from each group until a student is successful with that group of questions.

This Concept Builder consists of three different activities. Those three activities are described as follows:

• Which Bulb Will Light?: Question Groups 1-4. Learners identify which configurations of a cell, a bulb and a wire will result in a lit bulb.
• Pathways: Question Groups 5-10. Learners inspect the arrangement of two bulbs and two wires and determine the path of charge through the bulbs and wires and identify which of the two bulbs (if any) will light.
• Wire It Up Question Groups 11-18. Learners make decisions about where to attach a connecting wire in order to get a specified bulb or set of bulbs to light.

The questions from each group are shown below. Teachers are encouraged to view the questions in order to judge which activities are most appropriate for their classes. We recommend providing students two or more options.

The Physics Classroom grants teachers and other users the right to print these questions for private use. Users are also granted the right to copy the text and modify it for their own use. However, this document should not be uploaded to other servers for distribution to and/or display by others. The Physics Classroom website should remain the only website or server from which the document is distributed or displayed. We also provide a PDF that teachers can use under the same conditions. We have included a link to the PDF near the bottom of this page.
