Series: Electricity and Circuits
To make an electric circuit, some components like a power source (cell), a switch, and a load are needed. This video will teach students that a cell is a source of electric current with positive and negative terminals, a switch is a device that closes or opens a circuit, and how an appliance uses the electric current in the circuit in order to function.

In this video, students will learn how a parallel circuit works, including how each component is placed in its own separate loop, and that the failure of one component will not affect the working of the other components. Students will discover that parallel circuits are found in the electrical wiring of most households, which explains how the lights in the house don’t stop working when a TV or fan is turned off.

In this video, students will learn how a series circuit works, including how the components are joined together in one continuous loop and if one of its components malfunctions, then the other components also stop working. Students will discover that if an additional light bulb, besides the existing ones, is added to a series circuit, the glow of the bulbs becomes dimmer. Show Less
In this video, students will learn that various forms of energy can be converted into electrical energy including solar energy, batteries, hydroelectricity, nuclear power, windmills, and waves.
