This the smallest unit of chemical energy that can still retain the properties of the element.
What is an Atom?
100
Unit of energy; the amount of heat needed to raise one gram
of water one degree.
What is a Calorie?
100
A physical change that occurs when matter changes to
another state (i.e., liquid, gas, or solid).
What is Change of State?
100
Factor being measured or observed in an experiment?
What is the Dependent Variable?
200
This is the force of air pushing on an object.
What is Air Resistance?
200
This is a stable elemetary element that is negatively charged and orbit the nucleus of an atom.
What is an Eletron?
200
This is the change of state when a gas transforms into a liquid.
What is Condensation?
200
A reaction or a change in a substance produced by
chemical means that results in producing a different
chemical.
What is Chemical Reaction?
200
The factor that is changed in an experiment in order to study
changes in the dependent variable.
What is the Independent Variable?
300
This any periodic function the maximum variation of that function.
What is Amplitude?
300
This a substance that cannot be reduced to a smaller substance by chemical means.
What is an Element?
300
The transmission of heat through a medium and without the
motion of the medium.
What is Conduction?
300
An interconnection of electrical elements forming a
complete path for the flow of current.
What is a Circuit?
300
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.
What is an Experiment?
400
This is the highest point or peak of a wave.
What is a Crest?
400
A subatomic particle having zero charge, found in the
nucleus of an atom.
What is a Neutron?
400
A fundamental principle stating energy cannot be created
nor destroyed but only changed from one form to another.
What is Conservation of Energy?
400
A substance made up of a combination of two or more
elements held together by chemical bonds that cannot be
separated by physical means.
What is a Compound?
400
A procedure that is carried out in order to observe a
response caused by a stimulus; not a complete experiment.
What is an Investigation?
500
This is the change in direction of a wave due to an obstacle or opening.
What is a Diffraction?
500
A subatomic particle having a positive charge and which is
found in the nucleus of an atom.
What is a Proton?
500
Heat transfer in a gas or liquid by the circulation of currents
from one region to another.
What is Convection?
500
Concentration of matter of an object; number of individuals
in the same species that live in a given area; the mass per
unit volume of a substance in a given area.
What is Density?
500
A plan of inquiry that uses science process skills as a tool to
gather, organize, analyze, and communicate information.
