| Term | Definition |
|---|---|
| Matter | Anything that has mass and takes up space. |
| Physical Change | Any change that alters form or appearance of matter but does not change the substance. |
| Chemical Change | A change in matter that makes one or more new substances. |
| Weight | The pull on an object. |
| Mass | Matter in an object. |
| Qualitative | Made by gathering information that can be recorded using description language. |
| Quantitative | Made by gathering information that can be recorded as a number with a measurement unit. |
| Inference | Not a fact, but an interpretation of what the direct observations mean. |
| Scientific Law | Describes what scientists expect to happen every time under a particular set of conditions. |
| Constant | Part of an experiment that is held in the same condition for control and experimental. |
| Variable | Part of an experiment that changes. |
| Independent/Manipulated | A factor in a controlled experiment that is intentionally changed by the experimenter. |
| Scientific Theory | A well tested explanation for a wide range of observations or experimental results. |
| Inquire | To ask for information. |
| Dependent/Responding | A resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable. |
| Experiment | A course of action completed in order to test a hypothesis. |
| Control | A standard to which all other levels are compared in a scientific experiment. |
| Mixture | Matter that consists of two or more substances not chemically combined. |
| Compound | Two or more elements chemically combined. |
| Pure substance | A substance made of only one kind of material having a definite proportional amounts and properties. |
| Element | The simplest type of pure substance. |
| Homogeneous mixture | Two or more substances not chemically combined, but appearing to be evenly blended. |
| Heterogeneous mixture | Two or more substances not chemically combined, but appearing non-uniform with physically distinct substances included. |
| brittle | breaking into small pieces if bent or pressed |
| centimeter cubed | cm3; a unit of volume derived from length times width times height |
| compress | to squeeze or press together |
| condensation point | temperature at which a gas to turn liquid |
| deposition | a gas changing into a solid without changing into a liquid |
| dissolve | to break into pieces too small to be seen |
| ductile | able to be pulled into long, thin wires |
| flexible | able to bend without breaking |
| gas | state of matter having indefinite volume, indefinite shape, with particles bouncing around |
| gram per centimeter cubed | g/cm3; a derived unit used to measure density of a solid |
| gram per milliliter | g/mL; a derived unit used to measure density of a liquid |
| insulator | a material that does not allow electricity or heat to pass through easily |
| kinetic theory | a physics theory that all matter is made of moving particles in random motion |
| luster | shininess; the property of something that shines with reflected light. |
| magnetic | material that is attracted to magnets |
| malleable | able to be hammered or pressed into flat sheets |
| plasma | a state of matter consisting of ionized (electrically charged) particles |
| precision | the amount of detail or refinement in measurement |
| soluble | able to dissolve |
| sublimation | turning from solid to gas without turning into a liquid |
| texture | how something feels, especially whether it is bumpy or smooth |
