Terms | Definitions |
|---|---|
 matter | Anything that has mass and takes up space. |
| mass | The amount of matter in an object. |
| conductor | A substance that allows heat, electricity, and/or sound to pass through it easily. |
| insulator | A substance that does not allow heat, electricity, and/or sound to pass through it easily. |
| refraction | The bending of light waves. |
| concave Lens | A shape that bends light outward |
| convex Lens | A shape that bends light inward. |
| absorb | The process where matter takes in or traps radiant energy. |
| transmit | The process where radiant energy travels through matter. |
| mixture | When two or more substances are mixed together and can be physically separated. |
| solution | When two or more substances are mixed together but cannot be easily separated. |
| weight | A measure of the pull of gravity on an object. |
| physical change | The appearance of matter changes but the matter does not. |
| physical property | Characteristic of matter that can be observed using your senses. |
| volume | The amount of space that an object takes up |
| density | The amount of mass an object has in a known volume |
| solubility | The ability of a substance to be dissolved. |
| solid | Matter that has a definite shape and a definite volume. |
| liquid | Matter that has a definite volume but no definite shape. |
| gas | Matter that does not have a definite shape or volume. |
| vibrate | Move back and forth rapidly. |
| sound | Form of energy produced by vibrating objects |
| kinetic Energy | Energy of motion |
| potential Energy | Energy that is stored in an object. |
| state | one of the three main forms of matter |
| odor | how a substance smells |
| melting point | the temperature which a substance changes from a solid to a liquid. |
| texture | how a substance feels or looks |
| boiling point | the temperature which a substance changes from a liquid to a gas. |
| magnetic | substances attracted to objects containing iron. |
| invisible | cannot be seen |
| dissolve | to form a solution with another substance |
| force | a push or pull |
| friction | a force that works against motion |
| motion | movement |
| inertia | the tendency of an object to resist a change in motion |
| gravity | the force that pulls objects toward one another |
| light | a form of energy that travels in waves and in empty space |
| reflection | the bouncing back of light waves |
| energy | the ability to cause change in matter or make things happen. |
| solar energy | the energy from the sun |
| electrical energy | Energy that an object has because it has charged particles. |
| current | the movement of electricity in a certain path |
| opaque | materials that completely block the light waves from being transmitted; |
| transparent | materials that allow light to pass through easily. |
| translucent | materials that partially allow light to pass through. |
| property | a characteristic used to describe matter |
| solute | the substance that is dissolved in another substance |
| solvent | the substance that dissolves another substance |
| buoyancy | the ability to float |
| complete circuit | a closed path through which electricity travels with no breaks in the path |
| mechanical energy | energy that an object has because of where it is and how fast it is moving |
| thermal energy | produces heat |
| light energy | energy you can see that moves in waves and travels in a straight line |
| sound energy | energy that moves in waves and is caused by vibrating objects |
| heat energy | the movement of thermal energy |
| circuit | the path that electric current flows through |
