Science Reasoning Center - Electrostatics

There are two Electrostatics passages that target students' science reasoning abilities. They are ...
Charge Interactions
11 Questions
This passage provides background information regarding charge and charging methods and then describes an experiment in which various objects are charged by rubbing with animal fur. Information regarding their attractive and repulsive interactions is provided in the form of a data table. Questions target a student's ability to retrieve information from a body of text, to understand the design of an experiment, to draw conclusions that are consistent with observations, to make predictions based on a model, to identify the supporting evidence for a particular conclusion, and to predict the results of an additional trial in an experiment.
Sticky Tape Experiments
11 Questions
This passage describes a student experiment conducted with two pieces of sticky tape. The interaction of the tape with one another and with a variety of other objects is described. Questions target a student's ability to identify the supporting evidence for a particular conclusion, to draw conclusions that are consistent with two or more data presentations, to make predictions based upon a model, to predict the results of an additional trial, and to understand the design of an experiment.
On the Resource CD:
A Resource CD is being prepared to assist classroom teachers in using this section of the website more effectively within their classrooms. The Physics Classroom hopes to release the CD during the Fall semester of of 2014.

The Electrostatics section of the CD will include six different passages, including these two passages. The passages are accompanied by questions, answers with thorough explanations, and a table that associates each question with a specific science reasoning skill (or college readiness standard). Each passage includes considerably more questions than those presented here in the Science Reasoning Center. In addition to PDF files, the information on the CD is also available as Microsoft Word files, allowing teachers the ability to pick and choose questions from the large bank of questions associated with each passage.

More information about the CD can be found at the Resource CD page.
