Science Concepts

Gas

• A state of matter with a definite shape and volume.

• A state of matter that can be compressed easily.

• A state of matter without a definite shape or volume.

• A state of matter that has a fixed volume but no fixed shape.

Transverse

• A wave vibrating at right angles to the direction of its propagation.

• A wave that travels parallel to the direction of its propagation.

• A wave that does not require a medium to travel.

• A wave that moves in a circular motion.

Sound

• A form of energy that is associated with vibrations of matter.

• A type of wave that travels through a vacuum.

• A phenomenon that occurs only in liquids.

• A measure of the frequency of vibrations.

Block

• To allow something to pass through freely.

• To stop something from moving through or along something else.

• To enhance the movement of an object.

• To create a pathway for movement.

Pitch

• The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

• The loudness of a sound determined by its amplitude.

• The duration of a sound measured in seconds.

• The timbre of a sound that distinguishes different types of sound production.

Transmitted

• Passed on from one place or person to another.

• Completely destroyed or eliminated.

• Stored in a single location without movement.

• Ignored and left uncommunicated.

Mechanical

• Related to machines or the physical forces that produce motion.

• A term used to describe chemical reactions.

• A concept in biology related to living organisms.

• A type of energy that is not related to motion.

Wavelength

• The distance between successive crests of a wave.

• The speed of a wave in a vacuum.

• The amplitude of a wave.

• The frequency of a wave.

Partial

• Existing only in part; incomplete.

• Complete and whole.

• Fully developed and finished.

• Entirely present and accounted for.

Trough

• The highest point of a wave.

• The lowest point of a wave.

• The distance between two waves.

• The speed of a wave.
