Anything that has mass and takes up space

Smallest particle of an element

Pure substance made up of only one type of atom

State of matter with a definite shape and volume

State of matter with a definite volume, takes the shape of the container

State of matter with no definite shape or volume

Transition between different states of matter

Phase change from solid to liquid

Phase change from liquid to gas

Phase change from solid directly to gas

Phase change from liquid to solid

Phase change from gas to liquid

Phase change from gas directly to solid

Temperature at which a substance boils

Temperature at which a substance freezes

Amount of matter in an object

Measure of the force of gravity on an object

Amount of space occupied by an object. Use LxWxH for regular objects (cube, rectangular prism). Use water displacement for irregular objects.

Measure of how tightly packed the matter in an object is

Measure of the average kinetic energy of particles in a substance

Ability to do work or cause change

Transfer of thermal energy from a hotter object to a cooler object

Transfer of heat through direct contact

Transfer of heat through the movement of a fluid

Transfer of heat by electromagnetic waves that travel through open space.

s

Highest point of a wave

Lowest point of a wave

Distance between identical points on a wave

Number of waves occurring in a given time interval

Wave where the disturbance and energy travel in the same direction

Region of a longitudinal wave where particles are pushed together

Region of a longitudinal wave where particles are pulled apart

Movement of air in a longitudinal wave

Height of a wave, determines the volume of a sound

the highness or lowness of a sound due to frequency

Outer part of the ear that collects sound waves

Passageway from the outer ear to the middle ear

Membrane in the middle ear that vibrates in response to sound waves

Tiny bones in the middle ear (hammer, anvil, stirrup)

Part of the inner ear that detects sound vibrations

Nerve that sends sound information to the brain

Atoms/molecules slow down and come closer together

Atoms/molecules speed up and spread out

Heat always travels from hot to cold

State of matter with a definite shape and volume

State of matter with a definite volume, takes the shape of the container

State of matter with no definite shape or volume

A wave that requires a medium to travel through (ex. sound/longitudinal wave)

Sound travels fastest through solids, slower through liquids, and slowest through gases. This is due to the arrangement of particles.

A method used to determine the volume of an irregular solid

Splitting of white light into separate colors (by wavelength)

reflection of light in all directions

The bending of a wave as it passes at an angle from one medium to another

the bouncing back of a ray of light, sound, or heat when the ray hits a surface that it does not go through

All of the frequencies or wavelengths of electromagnetic radiation (radio, microwave, infrared, visible light, ultraviolet, x-ray, gamma ray)

A wave that moves the medium in a direction perpendicular to the direction in which the wave travels

electromagnetic waves that you can see

Colors of the visible spectrum in order of wavelength and frequency (red, orange, yellow, green, blue, indigo, violet)

The colored portion of the eye around the pupil and controls the size of the pupil opening

The clear tissue that covers the front of the eye

The opening through which light enters the eye

Light sensitive layer of the eye; contains rods and cones

Focuses light onto retina

Retinal receptors that detect black, white, and gray

Retinal receptors detects color (cones = color)

Carries visual information from the retina to the brain
