After building a simple electric motor from a kit, with this experiment you can explore how voltage affects motor speed. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction,...

A simple science fair project to test whether electricity can flow between two things. The Science Buddies project ideas are set up consistently beginning with an abstract, objective, and introduction, followed by a section on terms,...

In this science fair project, use a calorimeter with an attached heating element to measure how water responds to added thermal energy.

Objects that glow in the dark hold a special place in the imagination of both children and adults. The lights go out at night, but these odd things refuse to disappear. Where does the light come from? Do they work in any climate? In this...

Provides a long list of physics formulas for easy reference.

Explains what an LCR meter is and how it is used to measure the inductance, capacitance, and resistance of a circuit. Lists the different parameters of a circuit that it measures, describes two types of LCR meters, and gives definitions...

In this interactive, students can explore how current, voltage, and resistance are related in a model showing the flow of electrons in an electric circuit. They will learn about Ohm's law and how other forms of energy can be made from...

A superb explanation of how a battery works. Discusses the associated chemistry which explains how a battery produces a voltage. Includes a series of "Confidence Building Questions."

Kids learn about electricity glossary and terms in the science of physics. Words and definitions you need to know such as current, voltage, resistance, and more.

We solve a circuit by direct application of the fundamental laws: Apply element laws (Ohm's Law and the like) plus Kirchhoff's Laws to solve for the currents and voltages of a circuit.
