A quality that tends to produce movement or acceleration of a body in the direction of its application; a push or a pull.
What is force?
100
A subatomic particle having a positive charge and which is found in the nucleus of an atom.
What is a proton?
100
The process of changing from a gas (i.e., water vapor) to a liquid (i.e., dew); the act of making more dense or compact.
What is condensation?
100
The pivot point of a lever.
What is a fulcrum?
100
The event, condition, or factor that can be changed or controlled in order to study or test a hypothesis in a scientific experiment.
What is a variable?
200
The number of cycles or waves per unit time.
What is frequency?
200
A subatomic particle having zero charge, found in the nucleus of an atom.
What is a neutron?
200
A quantity that describes the capacity to do work; a source of usable power.
What is energy?
200
One of the fundamental states of matter in which molecules do not have fixed volume or shape.
What is gas?
200
A set of objects, organisms, or different parts acting to form a whole.
What is a system?
300
A force that opposes the relative motion of two material surfaces in contact with one another.
What is friction?
300
A particle, object, or system that lacks a net charge.
What is a neutral?
300
A change of energy from one form to another (e.g., mechanical to electrical, solar to electrical).
What is energy transfer?
300
A type of simple machine; a slanted surface that makes it easier to move a mass from a lower to a higher point.
What is an inclined plane?
300
A plan of inquiry that uses science process skills as a tool to gather, organize, analyze, and communicate information.
What is the scientific method?
400
A force of attraction between two masses.
What is gravitation?
400
A substance that cannot be reduced to a simpler substance by chemical means.
What is a element?
400
A measure of randomness or disorder of a closed system.
What is entropy?
400
A type of simple machine; consists of a rigid bar that pivots about a fulcrum, used to transmit and enhance power or motion.
What is a lever?
400
The factor that is changed in an experiment in order to study changes in the dependent variable.
What is an experiment?
500
The observed effect of the force of gravitation.
What is gravity?
500
A stable elementary particle that is negatively charged and orbits the nucleus of an atom.
What is a electron
500
The process in which a liquid is converted to its vapor phase by heating the liquid.
What is evaporation?
500
Electromagnetic radiation that lies within the visible range.
