Science Definitions
| Term | Definition |
|---|---|
| Qualitative Observations | made by gathering information that can be recorded using figurative language |
| Quantitative Observations | 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 condtions |
| Constant | part of an experiment that is held in the same condition for control and experimental |
| Variable | part of the experiment that changes |
| Manipulative Variable | a factor in a controlled experiment that is intentionally changed by the experimenter |
| Accuracy | the quality or state of being correct or precise |
| Calibration | the action or process of calibrating an instrument or experimental readings |
| Graduated Cylinder | piece of laboratory equipment used to measure the volume of a liquid |
| International System of Measurement | is the modern form of the metric system and is the world's most widely used system of measuremen |
| Liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume |
| Mass | a coherent, typically large body of matter with no definite shape |
| Matter | physical substance in general, as distinct from mind and spirit; (in physics) that which occupies space and possesses rest mass, especially as distinct from energy |
| Meniscus | the curved upper surface of a liquid in a tube |
| Newton-A Unit of Measurement | The SI derived unit used to measure force. One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second |
| Precision | the quality, condition, or fact of being exact and accurate |
| Triple Beam Balance | The Triple Beam Balance is a typical mechanical balance. It has a beam which is supported by a fulcrum. On one side is a pan on which the object is placed. On the other side, the beam is split into three parallel beams , each supporting one weight. |
| Unit | an individual thing or person regarded as single and complete but which can also form an individual component of a larger or more complex whole |
| Volume | the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great |
| Weight | a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing |
| Pure Substance | a substance of only one kind of material with definite properties |
| Mixture | matter that consists of two or more substances combined |
| Element | simplest form of pure substance |
| Compound | two or more substances chemically combined |
| Homogeneous Mixture | substances not chemically combined, but appearing to be evenly blended |
| Heterogeneous Mixture | substances not chemically combined, and appearing non-uniform with physically distinct substances included |
| Condensation Point | temperature where gas turns to liquid |
| Conductor | material that allows electricity to pass |
| Density | an objects mass compared to it's volume, mass divided by volume equals density |
| Deposition | gas changing to a solid but not a liquid |
| Ductile | able to be pulled into long thin wires |
| Flexible | able to bend without breaking |
| Freezing point | temperature where liquid turns to solid |
| Insulator | a material that does not allow electricity or heat to pass easily |
| Luster | shininess |
| Magnetic | attracted to magnets |
| Malleable | able to be hammered |
| Melting point | temperature when solid turns to liquid |
| Plasma | ionized parrticles |
| Sublimation | changing from solid to gas but not liquid |
