Electricity City vocabulary
| Term | Definition |
|---|---|
| Alternating Current | current in which the electrons reverse their direction regularly |
| Assumption | conclusions based on one’s beliefs and presuppositions |
| Bias | A one-sided or slanted view that may be based on culture, experience, or other aspects of one’s background |
| Blackout | lack of illumination caused by an electrical power failure |
| Blueprint | a drawing or other image, usually with white lines on a blue background, of an architectural plan |
| Brownout | a reduction or cutback in electric power, especially as a result of a shortage, a mechanical failure, or overuse by consumers |
| Boundary | something that indicates a border or limit |
| Charge | physical property of matter that can give rise to an electric force of attraction or repulsion |
| Circuit | complete path through which electricity can flow |
| Conductor | material which permits electrons to flow freely |
| Constant | the factor(s) in an experiment that remain the same |
| Control | the standard of comparison in an experiment |
| Current | flow of charge; measured in units called amperes |
| Dependent Variable | the variable that may be influenced by the independent variable |
| Direct Current | current consisting of electrons that flow constantly in one direction |
| Dysfunctional | not working properly |
| Electric Motor | device that uses an electromagnet to convert electrical energy to mechanical energy that is used to do work |
| Electrical Generator | device that converts mechanical energy to electrical energy by moving electrical conductors in the presence of a magnet |
| Electron | a negatively charged subatomic particle; electrons move around the nucleus of an atom |
| Element | essential component of a system |
| Filament | a thread of metal that is used to convert electricity into heat and light for the incandescent light bulb |
| Generator | that uses electromagnets to convert mechanical energy to electrical energy |
| Hypothesis | a tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation |
| Implication | a suggestion of likely or logical consequence; a logical relationship between two linked propositions or statements |
| Independent Variable | the variable that is changed intentionally by the experimenter |
| Inference | interpretation based on observation |
| Input | something put into a system |
| Insulator | material made up of atoms with tightly bound electrons that are not able to flow freely |
| Interaction | mutual action or influence of one element, individual, or group with another |
| Interdependent | mutually relying on or requiring the aid of another |
| Mean | the average value of a set of numbers |
| Median | the middle value in a distribution of numbers |
| Mode | the value or item occurring most frequently in a series of data |
| Model | a structural design or miniature representation |
| Neutron | a subatomic particle that possesses no charge |
| Ohm’s Law | expression that relates to current, voltage, and resistance |
| Output | a product of the system interactions |
| Parallel Circuit | circuit in which different parts are on separate branches; if one branch does not operate properly, current can still flow through the others |
| Perspective | an attitude, opinion, or position from which a person understands a situation or issue |
| Point of View | how people understand/look at things |
| Potential Difference | difference in voltage as created by opposite terminals of a battery |
| Power Surge | a sudden increase in the amount of current flowing through a power line |
| Productive | effective in achieving specified results |
| Property | a characteristic or attribute |
| Proton | a positively charged subatomic particle |
| Range | the difference between the smallest and largest values in a frequency distribution |
| Reasoning | evidence or arguments used in thinking |
| Resistance | opposition to the flow of electric charge; measured in ohms |
| Resistor | a device used to control current in an electric circuit by providing resistance |
| Scale | the size of a representation in proportion to the size of the actual items, as on maps |
| Series Circuit | circuit in which all parts are connected on after another; if one part fails to operate properly, the current cannot flow |
| Short Circuit | Circuit in which the electrons take a shorter path back to the power source rather than follow the usual longer path through a light bulb or other appliance |
| Stakeholder | an individual with an interest in or involvement with an issue and its potential outcomes |
| Switch | a device used to break or open and electric circuit |
| System | a group of interactive, interrelated, or interdependent elements that form a complex whole |
| Transformer | device that increases or decreases the voltage of alternating current |
| Transistor | device consisting of three layers of semiconductors used to amplify an electric signal |
| Turbine | engine turned by the force of gas or water on fan blades |
| Validity | accuracy and generalizability of the experiment’s outcomes |
| Voltage | potential difference; energy carried by charges that make up a current, measured in volts |
