Heat<br />Electrical<br />Light<br />Chemical <br />Energy comes in many forms: <br />
Heat<br />A form of energy that makes things warmer.<br />Most heat on Earth comes from the sun.<br />
Electricity<br />A form of energy that can be used to make heat and light, and to power machines<br />
Conductor<br />An object that lets heat or electricity go through easily.<br />
Insulator<br />An object that does not let heat or electricity go through easily<br />
Circuit<br />A path for an electric current<br />Often shown in a diagram with a battery, bulb, and wires<br />
Open Circuit<br />When the path of electricity is broken and the light does not come on<br />
Closed Circuit<br />When the path of electricity is complete and the light comes on<br />
Switch<br />A device for turning on or off electricity or an electric current<br />
Light<br />A form of energy that lets you see things-<br />Example: color<br />
