Science Definitions

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
