Science Reasoning Center - Electrostatics

There were two Electrostatic passages in the Legacy version that targeted students' science reasoning abilities. They have each been converted to a Version 2 activity. We have included the links below:


Charge Interactions
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
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.
