Term | Definition |
---|---|
Qualative | Made by gathering information that can be recorded using descriptive language. |
Quantative | Made by gathering information that can be recorded as a number with a measurement unit. |
Scientific Law | Describes what scientists expect to happen every time under a particular set of conditions. |
Inference | Not a fact, but an interpretation of what the direct observations mean. |
Constant | Part of an experiment that is held in the same condition for control and experimental. |
Variable | Part of an experiment that changes. |
Independent Variable | 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. |
Inquiry/Question | To ask for information. |
Dependent Variable | 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. |
Matter | Anything that takes up space and has mass. |
Physical Properties | Any change that alters the form or appearance of matter, but does not make any substance in the matter into a different substance;Changing the appearance,but not what it is. |
Chemical Properties | A change in matter that produces one or more new substances. |
Weight | Amount of gravity on an object. |
Mass | Amount of matter in an object. |
accuracy | Being correct or precise |
calibration | to determine, check, or rectify the graduation of (any instrument giving quantitative measurements). |
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 | 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 | composed of molecules that move freely among themselves but do not tend to separate like those of gases; neither gaseous nor solid. |
meniscus | The mark on the graduated cylinder that determines the amount of ml. |
Newton-a unit of measurement | One newton is equal to the force needed to accelerate a mass of one kilogram one meter per second per second. |
precision | Being accurate |
triple beam balance | A tool to measure mass |
unit | What something is measured as. |
volume | the amount of space, measured in cubic units, that an object or substance occupies. |
mixture | matter that consists of 2 or more substances not chemically combined. |
compound | 2 or more elements chemically combined. |
heterogeneous | 2 or more substances not chemically combined, and appearing non-uniform with physically distinct substances included. |
homogeneous | 2 or more substances not chemically combined, but appear to be evenly blended. |
element | the simplest type of pure substance. |
pure substance | a substance made of only one kind of material having definite proportional amounts and properties. |
