Science Vocabulary Words for MCAs
Here are common words and definitions that students should know to be prepared for the MCAs.
Anemometer- an instrument for measuring wind force and velocity
Spring Scale- a balance that measures weight by the tension on a spring (measured in Newton)
Balance- a weighing device to compare two objects
Thermometer-An instrument for measuring temperature, inside the colored water expands and rises in the tube as the temperature increases or decreases
Rain gauge- an instrument for measuring rainfall or snowfall
Weather vein-mechanical device attached to a high structure; rotates to show the direction of the wind (N,S,E,W)
Ruler-A straight edged strip of wood or metal, for drawing straight lines and measuring lengths (cm or in)
Meter stick- a long straight edge strip with measurements of meter, centimeter, and millimeter (metric)
Environments-The surroundings or conditions in which a person, animal, or plant lives or operates
Abiotic- Nonliving things: The abiotic factors of the environment include light, temperature, and atmospheric gases
Biotic- Living things: plants and animals
Food chains: Producers, consumers, and decomposers
Adapt-to adjust (someone or something) to different conditions, a new environment
Adaptation-inherited or acquired modification in organisms that makes them better suited to survive and reproduce in a particular environment
Animal structures-The arrangement or formation of the tissues, organs, or other parts of an organism
Ecosystem-involving the interactions between a community of living organisms in a particular area and its nonliving environment (biotic and abiotic)
Water cycle: Evaporation, condensation, precipitation, run-off
Changes in STATE of matter:
Add energy (heat): Solid →(Melting) → liquid → (Evaporation) →gas
Remove energy (cool): Gas→(Condensation) →liquid-→( Freezing) → solid
Parasite-An organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to the survival of its host. (ex. Tape worm)
Erosion- the wearing away of rocks and other deposits on the earth's surface by the action of water, ice, and wind
Germinate- to cause the embryo from a seed to sprout or grow
Organism- An individual form of life, such as a plant, animal, bacterium, protist, or fungus; a body made up of organs, organelles, or other parts that work together to carry on the various processes of life.
Organs- An organ is a structural part of a body system that is composed of tissues that enable it to perform a particular function.
Seed dispersal- the movement of seeds through wind, water, and animals
Open Circuit-an incomplete electrical circuit in which no current flows
Closed Circuit- An electric circuit providing an uninterrupted, endless path for the flow of current.
Electric circuit- Path for electricity that returns to energy source (closed or complete circuit)
Electromagnet- Magnet created using electricity. Benefit: Ability to turn on or off with a switch
Force- a push or pull (centrifugal, gravity, inertia, friction)
Energy- the capacity of a body or system to do work
Sound- Vibrations transmitted through a solid, liquid or gas
Pitch- The quality of a sound by the rate of vibrations producing it; the degree of highness or lowness of a tone.
Frequency- the number of occurrences of a repeating event over a unit of time (wavelength)
Tone- A sound of distinct pitch, quality, and duration; a note
Volume- the total amount of space a 3-dimension shape takes (length x width x height)
Variable- a change made in the system to create a different outcome (without changing the control)
Gravity- The force that attracts a body toward the center of the Earth (affecting weight but not mass of an object)
Translucent: Allowing light, but not detailed images, to pass through; semitransparent.
Transparent: Allowing light to pass through so that objects behind can be distinctly seen.
Opaque: Not able to be seen through; not transparent.
Reflect: to bounce back (heat, light, or sound) without absorbing it.
Redirect – to change direction
Refract: Make (a ray of light) change direction when it enters at an angle (through air, water or glass)
Absorb- to soak up (an object with absorb all the colors of the light spectrum but the color you see, black absorbs all colors, white reflects all colors)
Conductor: A substance that conducts heat, light, sound, or especially an electric charge (letting electrons flow)
Insulator- A material that insulates, especially a nonconductor of sound, heat, or electricity (holds electrons)
Crater- a depression formed in the Earth by the impact of a meteorite
Revolve- to orbit (spin) on a central point.
Orbit- to revolve around
Meteorites- A meteor that survives its passage through the earth's atmosphere and strikes the ground.
Asteroids- Any of numerous small, often irregularly shaped rocky bodies that orbit the Sun
Planets- A large body in outer space that orbits around a star (in our solar system the sun)
