Conduction - transfer of thermal energy between particles of matter that are touching.
Conductors - substances that transfer heat better than others.
Convection - transfer of thermal energy by particles moving through a fluid, a liquid, or a gas.
Convection Current - flow of particles in a fluid that occurs because of differences in temperature and density.
Density - the amount of mass per unit volume, determines whether an object will sink or float.
Heat - the transfer of thermal energy between substances
Insulators - substances that do not conduct heat easily
Specific Heat - the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree)
Thermal Energy - the kinetic energy of moving particles of matter, measured by their temperature.
Thermal Radiation - transfer of thermal energy by waves that can travel through air or across space
Volume - determines whether an object will sink or float

Vocabulary
absorption - the ability to take in or dampen
angle of incidence - angle at which light strikes a surface
angle of reflection - the angle at which light bounces off a surface

convex lens - a lens that is thicker in the middle than at the edge
electromagnetic radiation - the different energies emitted from the sun
lens - a transparent object with one or two curved surface
light - energy that travels in waves and is produced by hot, energetic objects
opaque - objects do not allow any light to pass through
prism - a clear glass or plastic medium that breaks light into the color spectrum
reflection - the bouncing back of light waves from a surface
refraction - when light goes from one medium to another and is bene
