a body in the direction of its application; a push or a pull
What is Force
100
a particle, object, or system that lacks a net charge
What is Neutral
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
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

100
factor being measured or observed in an experiment
What is Dependent Variable
200
the distance between crest of a wave
What is Wavelength
200
the smallest unit of a chemical element that can still retain
the properties of that element
What is Atom
200
the transmission of heat through a medium and without the
motion of the medium
What is Conduction
200
a type of simple machine; a circular lever, usually a wheel
with a groove where a rope can be placed and used to
change the direction of a force
What is Pulley
200
the factor that is changed in an experiment in order to study
changes in the dependent variable
What is Independent Variable
300
the lowest point on a wave
What is Trough
300
a stable elementary particle that is negatively charged and
orbits the nucleus of an atom
What is Electron
300
heat transfer in a gas or liquid by the circulation of currents
from one region to another
What is Convection
300
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 Lever
300
a set of objects, organisms, or different parts acting to form
a whole
What is System
400
the 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
400
a subatomic particle having a positive charge and which is
found in the nucleus of an atom
What is Proton
400
the process in which a liquid is converted to its vapor
phase by heating the liquid
What is Evaporation
400
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 Inclined Plane
400
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 Experiment
500
amount of distance traveled divided by time taken; the
time-rate at which any physical process takes place
What is Speed
500
a subatomic particle having zero charge, found in the
nucleus of an atom
What is Neutron
500
a fundamental principle stating energy cannot be created
nor destroyed but only changed from one form to another
What is Conservation Of Energy
500
the bouncing off or turning back of light, sound, or heat
from a surface
What is Reflection
500
the event, condition, or factor that can be changed or
controlled in order to study or test a hypothesis in a
scientific experiment
