"Hands-on" experiments developed by
science and education experts allow students to investigate electricity-from
conductors, insulators, resistors, capacitors, and thermal switches to
circuits in doorbells.
valuable thinking skills-observation, prediction, deductive reasoning,
conceptual modeling, theory building, and hypothesis testing-as they solve
Manipulatives, students can control, modify, and experiment with electrical
systems in a safe and accurate manner to visualize concrete and abstract
Circuits can be
viewed as they would actually appear (above), showing the flow of the
charges (below), or as a schematic (below).
Students can take the animated tour of the virtual laboratory for
demonstrations and instructions on how to use the tools.
They can check
the Quick Reference Cards (below left) and they can consult the Sci-Clopedia
(below right) for additional information about electricity topics.
