Triboelectric Charging - Questions
The Triboelectric Charging Concept Builder is comprised of 33 questions. The questions are divided into 16 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:
- What's the Charge: Question Groups 1-4. Information about the relative affinity that two objects have for electrons is given; learners must predict the charge that each object would have when rubbed together. They must also indicate the direction of particle transfer (electrons, protons or both) during the charging process.
- Triboelectric Series: Question Groups 5-10. A triboelectric series consisting of 15 different materials is given. Information about the charge acquired by an unknown material when rubbed against two or three of the listed materials is also given. Learners must indicate what area on the series that the unknown material should be placed.
- Rank the Material: Question Groups 11-16. Information about the charge acquired when three or four unknown materials are rubbed together is given. Learners must indicate how the three or four materials should be arranged in a triboelectric series.
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.
