Particles .. Words .. Formulas - Questions

The Particles .. Words .. Formulas Concept Builder is comprised of 36 questions. The questions are divided into 18 different Question Groups and spread across three difficulty levels. 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 difficulty levels are differentiated as follows:
 

• Apprentice Difficulty Level: Question Groups 1-6 ... Particle representations include only three elements; formulas are simple.
• Master Difficulty Level: Question Groups 7-12 ... Particle representations include only three elements; questions are slightly more complex.
• Wizard Difficulty Level: Question Groups 13-18 ... Particle representations include three elements; questions are complex.

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.
