Electricity and Heat
| Term | Definition |
|---|---|
| Attract | pull toward each other. |
| Celsius | Most scientists use this scale to measure temperature. Freezing point = 0:C, Boiling Point = 100:C |
| Closed Circuit | A complete, unbroken circuit to allow electricity to flow through it. |
| Conductor | A material that allows heat and electricity to pass through it. |
| Current | The flow of electrical charges through a circuit. |
| Energy Transfer | When energy flows from one object to another. Compass A tool that uses Earth's magnetic field to show direction. The needle of a compass is a thin needle that will point to a magnetic field (usually the Earth's). |
| Fahrenheit | This measurement of temperature is mainly used in America. Freezing point = 32:F, boiling point 212:F. |
| Heat | The transfer of thermal energy from one object to another. Heat always moves from warmer objects to cooler objects. |
| Insulator | A material that does not allow heat or electrons to move through it easily. |
| Magnet | An object that attracts to iron, nickel, and cobalt. |
| Magnetic Field | The area of magnetic force around a magnet. |
| Open Circuit | A circuit with gaps, so that it is not complete, and therefore, electricity will not flow through it. |
| Power Source | An object to power the electric current, such as a battery. |
| Property | Characteristic used to describe something |
| Repel | push away from each other |
| Simple Circuit | The path along which electric current flows. |
| Temperature | A measure of how hot or cold something is. |
