|---|---|
| Circuit | a closed conducting circle or loop through which current can flow |
| Closed circuit | a circuit that electricity can travel through (complete/working circuit) |
| Electric current | the flow of electricity through a conductor |
| Electrical energy | energy that is absorbed or delivered by an electric circuit |
| Energy | the ability to do work |
| Light energy | a form of energy which our eyes can detect |
| Mechanical energy | energy of motion (PE + KE = ME) |
| Medium | matter that energy travels through, such as solids, liquids, or gases |
| Open circuit | a circuit that electricity cannot travel through (incomplete circuit) |
| Reflection | the bouncing back of light rays from a surface |
| Refraction | the bending of light as it moves through one medium into another |
| Prism | A transparent object that refracts or bends and separates white light into the colors of the rainbow |
| Sound energy | energy produced by vibrations |
| Thermal energy | energy related to the temperature of an object or a substance |
| Conductor | A material that lets heat or electricity travel through it easily |
| Insulator | A material that does not let heat or electricity move through it easily |
| Series Circuit | An electric circuit in which the electrical charges have only one path to follow |
| Parallel Circuit | An electric circuit that has more than one path for the electric charges to follow |
| Chemical energy | Energy that can be released by a chemical reaction |
| Opaque | Not allowing light to pass through |
| Transparent | Allows light to pass through |
| Translucent | Allows only some light to pass through |
| Mixture | a combination of two or more substances that keep their physical properties (can usually be easily separated) |
| Solution | a mixture that when added to another substance, mixes evenly |
| Solubility | the ability of a substance to dissolve in another substance, such as sugar dissolving in water |
