Conductors and Insulators - Questions
The Conductors and Insulators Concept Builder is comprised of 72 questions. The questions are divided into 20 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 Difficulty Levels. Those three levels are described as follows:
- Apprentice Difficulty Level: Question Groups 1-4. Each question describes the initial charge state and the material type (conductor or insulator) of an object. Students must determine the final charge state of the object after it is touched to a charged object or the ground.
- Master Difficulty Level: Question Groups 5-12. Each question describes the initial charge state and the material type (conductor or insulator) of two connected objects. Students must determine the final charge state of the two objects after one of them is touched to a charged object or the ground.
- Wizard Difficulty Level Question Groups 13-20. Each question describes the initial charge state and the material type (conductor or insulator) of three connected objects. Students must determine the final charge state of the three objects after one of them is touched to a charged object or the ground.
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.
