Vocabulary:
(Lars) MATTER: Anything with __Mass__ and __Volume__. Matter matters! CLASSIFY MATTER: 1. How fast the particles move 2. How strong the attraction between particles(Atoms)(Lars) __Solid__ is "the state in which matter has definite shape and volume" (Holt Science and Technology; Physics, 759). Lead and wood are solids. (Lars) A solids' particles move slowly, vibrate in place, and have a strong attraction. There are 2 types of solids. Crystaline and Amorphous. An example of a Crystaline solid is a diamond or a bat. An example of an Amorphous object is silly putty or wax. Amorphous objects will shape if you shape it. But they won't shape on their own.(Lars)   Particles in a solid object are close together. __Liquid__ is "the state in which matter takes the shape of its container and has a definite volume" (Holt Science and Technology; Physics, 755). Water and oil are liquids. (Lars) A liquids particles move faster than a solids particles. They don't vibrate in place but they can slide past each other. Liquid molecules have a weaker attraction. Terms for liquids: Viscosity- Resistance to flow. Honey has a high viscosity.(Lars)

 Particles in a liquid are farther apart than those in a solid. __Gas__ is "the state in which matter changes in both shape and volume" (Holt Science and Technology; Physics, 754). Hydrogen and oxygen are gases. (Lars) Gaseous molecules are the fastest and have no attraction- they bounce off each other. Gaseous molecules move independently.(Lars)  Particles in a gas are spread far apart. __Plasma__ is "the state of mater that does not have a definite shape or volume and whose particles have broken apart; plasma is composed of electrons and positively charged ions" (Holt Science and Technology; Physics, 757). Lightning and fire are natural plasmas. (Lars) The stars and the sun are also natural plasmas. Plasmas have no definite shape or volume. They conduct an electric current and are broken atoms(particles) that inside are possitive or negative charges. They are also affected by magnetic fields. Did you know 99% of the universe is plasma(Lars) Particle Theory: Matter is made up of particles.(Atoms)(Lars) Kinetic Theory: All matter is in constant motion.(Lars)
 * The terms above are the four states of matter.

Unit Objectives:
1) All matter is in constant motion 2) The four states of matter are solid, liquid, gas, and plasma 3) Matter can be classified by its particles and how they move 4) Before a temperature change can take place all particles must complete their phase change before the temperature rises
