Grade 4 Electricity
| Question | Answer |
|---|---|
| D-Cell | the source of electricity |
| Battery | more than one cell |
| electricity source | provides the energy to light the bulb |
| electricity receiver | a component that uses the electricity from the source to make something happen |
| circuit | a pathway for the flow of electricity |
| filament | the part of a bulb that gets hot and produces light |
| components | D-cells, bulbs, and wires are circuit parts |
| circuit base | holds many components needed to build a circuit |
| Fahnstock clip | metal clip that connects wires in a circuit |
| switch | a device used to open and close circuits |
| open circuit | an incomplete circuit through which electricity will not flow |
| closed circuit | a complete circuit through which electricity flows |
| schematic diagram | a way to represent a circuit on a piece of paper |
| circuit needs | a source of energy (D-cell), a receiver (the bulb), and a path to get from one to the other (wires) |
| circle | the complete path the electricity must travel from one battery end to the other |
| motor | an electricity receiver that produces motion |
| switch | a device that opens and closes the circuit |
| Set of symbols | people must agree upon them in order to read and understand schematic diagrams or drawings that represent circuits |
