8th Physical Science
| Term | Definition |
|---|---|
| Qualitative | made by gathering information that can be recorded using descriptive 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 the experiment that changes |
| MV | a factor in a controlled experiment that is intentionally changed by the experimenter |
| Theory | a well tested explanation for a wide range of observations or experimental results |
| Inquiry | to ask for information |
| DV | a resulting factor in a controlled experiment that is observed and measured to see if it changes due to the manipulation of another variable |
| Experimant | 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 |
| Matter | has mass and takes up space |
| Physical Properties | a characteristic of a pure substance that can be observed WITHOUT CHANGING IT into another substance |
| Chemical Properties | a characteristic of a pure substance that describes its ability to change into a differnt substance |
| Newton | a unit of force required to move 1 kilogram 1 meter squared |
| Work | force exerted on an object that causes it to move |
| Force | a push or pull exerted on an object |
| Gravity | a force that attracts objects |
| Newtons 1st law | An object at rest stays at rest or an object that is moving at a speed in a straight line keeps moving at that speed unless another force acts on it |
| Newtons 2nd law | the amount of force needed to make an object change its speed depends on the mass of the object and the acceleration required |
| Newtons 3rd law | for ever action (or force), there is an equal and opposite action (or force) |
| Mechanical Advantage | the ratio of the output force produced by a machine to the applied inputforce |
| accuracy | the extent to which a given measurement agrees with the standard value for that measurement. |
| calibration | to divide or mark with gradations, graduations, or other indexes of degree, quantity, etc., as on a thermometer, measuring cup, or the like |
| graduated cylinder | a narrow, cylindrical container marked with horizontal lines to represent units of measurement and used to precisely measure the volume of liquids. |
| International System of Measurement | (abbreviated SI from French: Le Système International d'Unités) is the modern form of the metric system and is the world's most widely used system of measurement, used in both everyday commerce and science. |
| liquid | having a consistency like that of water or oil, i.e., flowing freely but of constant volume |
| mass | a body of coherent matter, usually of indefinite shape and often of considerable size |
| matter | the substance or substances of which any physical object consists or is composed |
| meniscus | the curve of the water in a graduated cylinder |
| Newton | the standard unit of force in the International System of Units (SI), equal to the force that produces an acceleration of one meter per second per second on a mass of one kilogram. |
| precision | the state or quality of being precise. |
| triple beam balance | an instrument used to measure weight |
| unit | a single thing |
| volume | the amount of space, measured in cubic units, that an object or substance occupies. a mass or quantity, especially a large quantity, of something |
| weight | the force that gravitation exerts upon a body, equal to the mass of the body times the local acceleration of gravity: commonly taken, in a region of constant gravitational acceleration, as a measure of mass |
| matter | anything that has mass and volume (takes up space) |
| pure substance | a substance made of only one kind of material having definite proportional amounts and properties |
| mixture | matter that consists of two or more substances not chemically combined |
| element | the simplest type of pure substance |
| compound | two or more elements chemically combined |
| homogeneous mixture | two or more substances not chemically combined, but appearing to be every blaended |
| heterogeneous mixture | two or more substances not chemically combined, and appearing non-uniform with physically distint substances included |
