Biology
a characteristic of an organism that increases its chance of survival in its environment
adaptation
the smallest unit of a chemical element that can still retain the properties of that element
atom
the layers of gas that surround the Earth, other planets, or stars
atmosphere
a quantity that describes the capacity to do work; a source of usable power
energy
concentration of matter of an object; mass per unit volume of a substance in a given area; the number of individuals of the same species in a given area
density
an animal or plant that consumes or obtains nutrients from animals
carnivore
a physical change that occurs when matter changes to another state (to liquid gas or solid)
change of state
an imaginary circle around Earth’s surface located between the poles and a plane perpendicular to its axis of rotation that divides it into the Northern and Southern Hemispheres
equator
a change of energy from one form to another (e.g., mechanical to electrical, solar to electrical)
energy transfer
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
experiment

investigation
a pyramidal diagram that compares the amount of energy available at each position, or level, in the feeding order
energy pyramid
the process in which a liquid is converted to its vapor phase by heating the liquid
evaporation
the process by which sediment is carried by forces (e.g., wind, rain, or water currents) and left in a certain area; layering matter in a natural process.
deposition
the pivot point of a lever
fulcrum
a plan of inquiry that uses process skills as a tool to gather, organize, analyze, and communicate information
scientific method
transfer of energy through various stages as a result of feeding patterns of a series of organisms
food chain
