5th Grade Vocabulary
| Word | Definition |
|---|---|
| circuit | a path through which electricity flows |
| conduct | to allow an electric current to pass |
| conduction | transfer of heat from a warmer substance to a cooler substance through direct contact |
| conductor | a substance, commonly a metal such as copper or aluminum, that has low resistance to electric current and through which electricity will flow |
| crystal | a piece of solid, often transparent material with shiny, flat surfaces that can be identified by its special shape or pattern |
| density | the ratio of the mass of a material in proportion to its volume |
| dilute | to make a solution less concentrated, usually by adding more liquid |
| dissolving | when a substance is no longer visible when it is mixed in a liquid |
| electricity | the interaction of electric charges |
| electromagnet | a coil of wire usually wound around a core of iron or steel, which produces a magnetic field when electricity flows through the wire |
| energy | the ability to do work |
| evaporation | the process by which a liquid changes into a gas |
| geothermal energy | heat energy from inside the Earth |
| heat | transfer of thermal energy between substances that are at different temperatures |
| ingredients | one or more materials that go into a mixture or solution |
| insulate | to prevent or reduce the passage of electricity, heat, or sound |
| lens | a piece of glass that is curved on one or both sides |
| light | a special kind of energy that makes it possible for us to see, consisting of waves moving out from a source |
| magnetism | the properties of magnets and their attraction towards iron |
| mass | the amount of matter in an object |
| matter | anything that has mass and takes up space |
| mixture | a combination of two or more materials that keep their same properties when combined |
| parallel circuit | a closed circuit in which the current divides into two or more paths before recombining to complete the circuit |
| physical properties | property of matter that can be observed without changing its make up |
| produce | to bring into existence; to cause or to make |
| property | characteristic of a substance that can be observed or measured |
| radiation | transfer of thermal (heat) energy in the form of waves |
| reflection | something that is bounced off something else |
| refraction | the bending of light as it passes from one material to another |
| saturated solution | a solution in which no more material will dissolve, with additional material settling to the bottom |
| series circuit | an electric circuit connected so that current passes through each circuit element in turn |
| solar energy | energy from the sun |
| change | to make or become different |
| solubility | the property that substances have of dissolving in solvents, such as the solubility of salt in water |
| solute | a substance tha dissolves into another substance |
| solution | a special mixture formed when a material dissolves in a liquid and cannot be filtered out |
| solvent | the material that the solute dissolves into |
| sound | energy that travels through matter in waves and can be heard by the ear |
| substances | a solid, liquid, or gas; matter |
| temperature | the measure of how hot or cold something is |
| vibrating | rapid back and forth movements |
| volume | the amount of space something takes up |
| weight | the amount of gravitational pull on an object |
| concentration | the relative amount of a substance in a mixture |
