angle: The distance (usually measured in degrees) between two intersecting lines or surfaces at or near the point where they meet.
biology: The study of living organisms. Scientists who study living organisms are called biologists.
celestial: (in astronomy) of or relating to the sky or universe.
celestial bodies: Naturally formed objects of significant size in outer space. Examples include comets, asteroids, planets, moons, stars, and galaxies.
cell: (biology) The smallest structural and functional unit of an organism. Usually too small to be seen with the naked eye and composed of a watery fluid surrounded by a membrane or wall. Animals are composed of thousands to trillions of cells, depending on their size. Most organisms, such as yeasts, molds, bacteria, and some algae, are composed of only a single cell.
cloud: A plume of molecules or particles, such as water droplets, that moves under the action of external forces, such as wind, radiation, or water currents. (in atmospheric science) A mass of airborne water droplets and ice crystals that usually moves as a plume through the upper atmosphere of the Earth, its movement being driven by wind.
computer programs: A set of instructions that a computer uses to perform some analysis or calculation. Writing these instructions is called computer programming.
corn: (biology) A type of eye cell that is part of the eyeball. retina They are found at the back of the eye. These cells can detect red, green, and blue light. Recent studies have found evidence that many cells can also detect white light. However, they can only detect white light.
sign: The pattern formed by prominent stars that appear close together in the night sky. Modern astronomers divide the sky into 88 constellations, 12 of which (known as the zodiac) lie along the path that the sun moves across the sky during the year. Cancri is the original Greek name for Cancer, one of the 12 zodiacal constellations.
data: Facts or statistics collected for analysis, but not necessarily organized in a meaningful way. In the case of digital information (the type stored in a computer), these data are usually numbers stored in binary code, represented as a string of 0s and 1s.
degree: (in geometry) a unit of measurement for angles, one degree being equal to 1/360th of the circumference of a circle.
diameter: The length of a straight line that passes through the center of a circular or spherical object, starting at one end and ending at the opposite end.
malaise: Feeling tired, lethargic, or lacking energy.
seaweed: A sticky substance that adheres one substance to another.
illusion: Something that is or can be mistakenly perceived or interpreted by the senses.
information: (as opposed to data) A fact provided about something or someone, or a trend learned, often as a result of the study of data.
monitor: To test, try, or observe something, especially on a regular or ongoing basis.
month: A natural satellite of every planet.
number: Something related to numbers.
phenomenon: Something surprising or unusual.
retina: A layer at the back of the eyeball that is sensitive to light and contains cells that trigger nerve impulses that travel down the optic nerve to the brain, where visual images are formed.
square: (in geometry) A rectangle with four sides of equal length.
sun: The star at the center of Earth’s solar system, about 27,000 light-years away from the center of the Milky Way galaxy. Also a term used to refer to all stars like the Sun.
theory: (in science) An explanation of some aspect of the natural world based on extensive observation, testing, and reasoning. A theory is also a way of organizing a broad body of knowledge that applies to a variety of situations and explains what happens. Unlike the common definition of a theory, a theory in science is not just a hunch. Ideas and conclusions that are based on theory and not yet based on hard data or observations are called theoretical. Scientists who use mathematics and existing data to predict what will happen in new situations are known as theorists.
