Charge Interactions - Questions

The Charge Interactions Concept Builder is comprised of 24 questions. The questions are divided into 12 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.

There are three different difficulty levels that can be engaged in through the Concept Builder. Those three levels are differentiated as follows:
 
  • Apprentice Difficulty Level: Question Groups 1-4. Interactions between four objects are described; must identify the type of charge of three of the objects.
  • Master Difficulty Level: Question Groups 5-8. Interactions between five objects are described; must identify the type of charge of four of the objects.
  • Wizard Difficulty Level: Question Groups 9-12. Interactions between six objects are described; must identify the type of charge of five of the objects.

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.
