The program offers students the opportunity to study various types of circuits and gives them instructions so they can explore the effects of manipulating portions of these circuits. Students can also explore circuits of their own design by choosing and organizing circuit components from a toolbar. The program is fairly simple to navigate.
Students choose from a well-labeled menu of possible experiments.
Once children have chosen an experiment, each component of the circuit in that experiment appears on the screen as a picture and is appropriately connected with wires to other components. Helpful hints appear each time the cursor passes over one of these components, explaining how the parts can be removed, replaced and altered. Each experiment includes a written procedure and follow-up questions. Unfortunately, the procedure screen and simulation cannot be viewed at the same time, so it makes sense to print the instructions and follow-up questions before attempting the simulation. Also, there is no solution set to the follow-up questions, so a student needs access to a knowledgeable adult to check his or her answers.
