rate of change in velocity, usually expressed in meters per
second; involves an increase or decrease in speed and/or a
change in direction
What is Acceleration
100
a subatomic particle having a positive charge and which is
found in the nucleus of an atom
What is a Proton
100
a change of energy from one form to another (e.g.,
mechanical to electrical, solar to electrical)
What is energy transfer
100
a reaction or a change in a substance produced by
chemical means that results in producing a different
chemical
What is chemical change
100
factor being measured or observed in an experiment
What is a dependent variable
200
in any periodic function (e.g., a wave) the maximum
absolute variation of the function
What is Amplitude
200
a stable elementary particle that is negatively charged and
orbits the nucleus of an atom
What is a Electron
200
a measure of randomness or disorder of a closed system
What is entropy
200
a reaction or a change in a substance produced by
chemical means that results in producing a different
chemical
What is change of state
200
the factor that is changed in an experiment in order to study
changes in the dependent variable
What is an independent variable
300
the change in direction of a wave caused by passing by an
obstacle or traveling through an opening
What is diffraction
300
a subatomic particle having zero charge, found in the
nucleus of an atom
What is a nuetron
300
the energy possessed by a body because of its motion
What is kinetic energy
300
the pivot point of a lever
What is a fulcrum
300
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
400
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
400
a substance that cannot be reduced to a simpler substance
by chemical means
What is an element
400
energy stored in an object due to the object’s configuration
and position
What is potential energy
400
a type of simple machine; consists of a rigid bar that pivots
about a fulcrum, used to transmit and enhance power of
motion
What is a lever
400
a plan of inquiry that uses science process skills as a tool to
gather, organize, analyze, and communicate information
What is the scientific method
500
property of an object, due to its mass, that causes it to
resist any change in its motion unless overcome by a force
What is inertia
500
a stable elementary particle that is negatively charged and
orbits the nucleus of an atom
What is an electron
500
emission of energy in the form of rays or waves
What is radiation
500
having the property of attracting iron and certain other
materials by virtue of a surrounding field of force
What is magnetic
500
a procedure that is carried out and repeated under
controlled conditions in order to discover, demonstrate, or
test a hypothesis; includes all components of the scientific
method
