Electricity Explorer, geared to students in middle school and high school, consists of a number of components dealing with the simpler concepts of electricity. The program was very easy to use and, once loaded, did not require directions to operate. Students will find many parts of the CD-ROM entertaining as well as challenging. The section titled "How Things Work" provides a tutorial on the basic concepts of atomic structure, electron flow, electrical laws, and circuits. The tutorial is presented at two levels of difficulty and would make a good review for students who need extra work or have missed a class.

The "Meter Reader" portion allows students to manipulate circuits of various types and test them for amp, volt, and ohm values. This is presented like an open-ended lab in which the students choose the configuration of the circuit, position the meters, and try the different readings. Once they have become proficient in this area they can move into the "Predictions" section, which gives them a particular circuit arrangement and asks them to answer a question concerning its values. This could easily be used in a one-computer classroom as a class exercise.

Math skills are required in the exercises using Ohm's Law and Kirchoff's Law. …
