usually solid, liquid, and gas
matter
everything in the universe that has mass
and takes up space
solid
the state of matter that has a definite
shape and takes up a definite amount of
space
liquid
the state of matter that takes the shape of
its container and takes up a definite
amount of space
gas
the state of matter that has no definite
shape and takes up no definite amount of
space
graduated cylinder
a piece of laboratory glassware or
plasticware used to accurately measure
out volumes of chemicals
volume
the amount of space that matter takes up
buoyancy
the ability of matter to float in a liquid or
gas
density
the property of matter that compares the
amount of matter to the space it takes up
microscope
is an instrument for viewing objects that
are too small to be seen by the naked or
unaided eye
circuit
a path that is made for an electric current
conduction
the direct transfer of heat between objects
that touch
conductor
a material that electric current can pass
through easily
electric cell
a battery that supplies energy to move
charges through a circuit
electric current
a flow of electric charges
parallel circuit
a circuit that has more than one path
along which current can travel
climate
the average temperature and rainfall of an
area over many years
meteorologist
a person who studies or predicts the
weather
tornado
an intense windstorm that often forms
within a severe thunderstorm
hurricane
a large, spiraling storm system that can be
a much as 600 km across
symmetry
the condition in which each feature on one
half of an object has a matching feature
on the other half
reflection
the bouncing of light off an object
metamorphosis
a change in the shape or characteristics of
an organism's body as it grows
photosynthesis
the process by which a plant makes its
own food
transpiration
the process by which plants lose water to
the air
extinct

the last individual of a population dies and

weathering
the process by which rocks are broken
down into smaller pieces

sediment over millions of years
sediment
any particulate matter transported by fluid
flow, which eventually is deposited as a
layer of solid particles on the bed or
bottom of a body of water
erosion
the movement or transportation of
sediment to new locations
dissolve
when one material forms a solution with
another material
mineral
a natural, solid material with particles
arranged in a repeating pattern
energy
the ability to cause changes in matter; the
ability to do work
hypothesis
predicts the outcome of an experiment
an educated guess
conclusion
After your experiment, you analyze your data
and draw a conclusion. Was your hypothesis:
-right?
-or was it wrong?
Either way, your need to share what
you have learned next.
theory
taking what you learned from previous
experiments and in the world around you
to explain existing observations and to
predict new ones
inexhaustible resource
a resource, such as air or water, that can
be used over and over and can not be
used up
renewable resources
resources that can be replaced in a
human lifetime
non-renewable resources
a resource that cannot be readily replaced
once it is used
parallel circuit
a circuit that has more than one path
along which current can travel
melting point
the temperature range at which it changes
its state from a solid to a liquid
translation (slide)
a movement of a figure along a straight
