Rate of change in velocity, usually expressed in meters per second; involves an increase or decrease speed and/or a change in direction.
What is Acceleration?
100
The smallest unit of a chemical element that can still retain the properties of that element.
What is an Atom?
100
The transmission of heat through a medium and without the motion of the medium.
What is Conduction?
100
An interconnection of electrical elements forming a complete path for the flow of current.
What is a Circuit?
100
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?
200

What is Force?
200
A substance that cannot be reduced to a simpler substance by chemical means.
What is an Element?
200
Heat transfer in a liquid or gas by the circulation of currents from one region to another.
What is Convection?
200
The product of a thorough blending of two or more substances, not chemically combined.
What is a Mixture?
200
A procedure that is carried out in order to observe a
response caused by a stimulus; not a complete experiment.

500
Internal energy found by adding the kinetic energy of particles making up a substance.
What is Thermal Energy
500
A type of simple machine that consists of a rod driven
through the center of a cylinder that is allowed to rotate
freely, yielding a mechanical advantage equal to the
cylinder’s diameter.
What is a Wheel and Axle
500
Factor being measured or observed in an experiment.
