8th Physical Sci

hey dude

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 scientist 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 experiment.
Variable Part of the experiment that changes.
Manipulated 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 To ask for information.
Responding Veriable 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 has mass and takes up space.
Physical Properties A pure substance that can be observed without changing it.
Chemical Properties A pure substance that describes it's ability to change.
Work Force exerted on an object that causes it to move.
Force A push or pull exerted on an object
Newton (N) A unit of force required to move 1 kilogram 1 meter squared.
Newton's first 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.
Newton's second law The amount of force needed to make an object change its speed depends on the mass of the object and the acceleration required.
Newton's third law For every action (or force), there is an equal and opposite action (or force).
Gravity The force that pulls objects toward each other.
Mechanical Advantage The ratio of the output force produced by a machine to the applied input force.
Accuracy The quality or state of being correct or precise.
Calibration The action or process of calibrating an instrument or experimental readings.
Graduated Cylinder A graduated cylinder, measuring cylinder or mixing cylinder is a piece of laboratory equipment used to measure the volume of a liquid.
International System of Measure (SI) The International System of Units 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 Liquid is one of the four fundamental states of matter, and is the only state with a definite volume but no fixed shape.
Mass In physics, mass is a property of a physical body which determines the body's resistance to being accelerated by a force and the strength of its mutual gravitational attraction with other bodies.
Matter The substance or substances of which any physical object consists or is composed.
Meniscus The meniscus is the curve in the upper surface of a liquid close to the surface of the container.
Newton- A unit of measure The newton is the International System of Units (SI) derived unit of force.
Precision The quality, condition, or fact of being exact and accurate.
Triple beam balance The triple beam balance is used to measure masses very precisely.
Unit A quantity chosen as a standard in terms of which other quantities may be expressed.
Volume Volume is the quantity of three-dimensional space enclosed by some closed boundary.
Weight The weight of an object is usually taken to be the force on the object due to gravity.
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 a pure substance.
Compound Two or more elements chemically combined.
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.
