1) Chemical energy: occurs when two or more chemicals mix together which causes a chemical reaction. A chemical reaction is an event in which a chemical change occurs
2) Circuit: path followed by electrons as they travel through conductors. The distance around an area or object
3) Conductor: substance that allows electricity or heat to flow through it easily
4) Electrical energy: one of the most useful forms of energy. It is used in heat and light, which are two very valuable things that would be difficult to live without
5) Electromagnet spectrum: the wide range of wavelengths from lower frequencies such as radio waves, short wave, AM, FM, TV, and radar to infrared rays, visible light and ultraviolet, and, finally, the shorter wavelengths of x-rays and gamma rays
6) Electrons: negatively charged particles circling the nucleus of an atom
7) Fossil fuel: oil, natural gas, and coal formed from bodies of ancient plants and animals
8) Energy: the ability to do work or cause change
9) Infrared light: part of the electromagnetic spectrum, which is the ability to see galaxies immediately after they form, also it lets us see through the dust to witness the cradles of star birth
10) Nuclear fission: the spitting of atoms
11) Nuclear energy: the strongest type of energy that scientists use
12) Potential energy: stored energy; energy at rest as a result of its state or position 13) Kinetic energy: refers to movement or energy of motion
14) Refraction: bending of light rays passing through substances of different densities
15)
