Ecology
All the same species of living things (organisms) in an area
Population
The stage of the water cycle where water turns into vapor.
Evaporation
This word means "something that is able to change"
Variable
A push or pull on an object
Force
Energy generated from movement
kinetic energy
A living (or once-living) thing that influences an ecosystem
Biotic
The layer of gas surrounding the earth
Atmosphere
This is the effect that results from the scientist's manipulation of variables in an experiment.
Dependent Variable
A force that opposes the motion of an object.
friction
A word meaning "heat energy"
Thermal energy
A non-living thing that influences an ecosystem (meaning never living)
Abiotic
Climate
This is a variable that a scientist introduced into an experiment that causes a change in an experiment's outcome.
Independent variable
Speed in a given direction
Velocity
The stored energy in an object due to its position, state, or arrangement.
Potential energy
Decomposers
The stage in the water cycle where falls from clouds.
Precipitation
Variables that remain constant throughout the experiment.
Control Variable
The force that causes some materials to attract or repel each other without touching
Magnetism
This resource, mostly consisting of ancient plants and animals, can be used to create energy by burning it.
Fossil Fuels
All the biotic factors (community) and abiotic factors in an area
Ecosystem
The process of water vapor cooling and changing from a gas back into liquid droplets, forming clouds.
Condensation
The rate at which an object's velocity changes over time, covering speeding up, slowing down, or changing direction
Acceleration
Matter
