The pressure of the atmosphere usually expressed in terms of the height of a column of mercury.
A reaction or a change in a substance produced by chemical means that results in producing a different chemical.
An interconnection of electrical elements forming a complete path for the flow of current.
A celestial body that appears as a fuzzy head usually surrounding a bright nucleus, that has a usually highly eccentric orbit, that consists primarily of ice and dust, and that often develops one or more long tails when near the sun.
To cause to pass into solution.
The different species in a given area or specific period of time.
The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge.
The capacity to do work.
The sum of conditions affecting an organism, including all living and nonliving things in an area, such as plants, animals, water, soil, weather, landforms, and air.
The process by which a liquid is converted to its vapor phase by heating the liquid.
A theory that the various types of species arise from pre-existing species and that distinguishable characteristics are due to modifications through successive generations.
A hard outer structure, such as the shell of an insect or crustacean, that provides protection and/or support for an organism.
A procedure that is carried out and repeated under controlled conditions in order to discover, demonstrate, or test a hypothesis.
A vector quantity that exists between two objects and, when unbalanced by another force, causes changes in velocity of objects in the direction of its application; a push or pull.
To pass from the liquid to the solid state by loss of heat from the substance/system.
A large collection of stars, gases, and dust that are part of the universe (e.g., the Milky Way galaxy) bound together by gravitational forces.
One of the fundamental states of matter in which the molecules do not have a fixed volume or shape.
The force of attraction between any two objects.
A place in an ecosystem where an organism normally lives.
Energy that transfers between substances because of a temperature difference between the substances; the transfer of energy is always from the warmer substance to the cooler substance
The amount of water vapor in the atmosphere, usually expressed as either absolute humidity or relative humidity.
A systematic process that uses various types of data and logic and reasoning to better understand something or answer a question.
A measure of relative position north or south on the Earth's surface, measured in degrees from the equator, which has a latitude of 0°, with the poles having a latitude of 90° north and south.
The entire sequence of events in an organism's growth, development, and reproduction.

One of the fundamental states of matter with a definite volume but no definite shape.
Having the property of attracting iron and certain other materials by virtue of a field of force.
The amount of matter an object contains.
Substance that possesses inertia and occupies space, of which all objects are constituted.
An instrument with lenses and light that is used to observe objects too small to be visible with only the eyes.
A systematic description of an object or phenomenon that shares important characteristics with the object or phenomenon. Scientific models can be material, visual, mathematical, or computational and are often used in the construction of scientific theories.
A natural satellite that revolves around a planet.
The act or process of changing position and/or direction.
Expressing or dealing with facts or conditions as perceived without distortion by personal feelings, prejudices, or interpretations.
What one has observed using senses or instruments.
A path described by one body in its revolution about another (as by the earth about the sun or by an electron about an atomic nucleus).
A structure containing different tissues that are organized to carry out a specific function of the body (e.g., heart, lungs, brain, etc.)
An individual form of life of one or more cells that maintains various vital processes necessary for life.
A large body in space that orbits a star and does not produce light of its own.
The rate at which work is done, expressed as the amount of work per unit time and commonly measured in units such as the watt and horsepower.
In meteorology, a form of water, such as rain, snow, or sleet that condenses from the atmosphere, becomes too heavy to remain suspended, and falls to the Earth's surface.
An organism, usually a plant or bacterium, that produces organic compounds from simple inorganic molecules and energy (typically light energy) from the environment.
A process that uses science process skills as tools to gather, organize, analyze, and communicate information.
A person with expert knowledge of one or more sciences, that engages in processes to acquire and communicate knowledge.
Any of the faculties by which stimuli from outside or inside the body are received and felt, as the faculties of hearing, sight, smell, touch, taste, and equilibrium.
The internal structure of vertebrate animals, composed of bone or cartilage, that supports the body, serves as a framework for the attachment of muscles, and protects the vital organs and associated structures.
A star and all the planets and other bodies that orbit it; the region in space where these bodies move.
Having a definite shape and a definite volume; one of the fundamental states of matter.
