Matter An Insight Into The Structure and Properties of Matter  What Is Matter?  Matter is anything that has mass and volume.  A cup, pen, and eraser are made up of matter  What Is Matter?  The definition of matter is often taken to mean anything composed of atoms and molecules.  Thus, matter is anything made of protons, neutrons, and electrons.  Structure Of Matter  The atom is the “building block of matter”.  All substances are composed of invisible particles called atoms.  Atoms are the building blocks of matter and are in constant motion.  The combination of atoms leads to millions of materials with different properties.  Atoms Atoms are composed of three types of particles: protons, neutrons, and electrons.  Nucleus  Atoms are made up of a positively charged center, the nucleus, containing: - Protons with a positive charge - Neutrons with no charge (neutral) Nucleus O = Neutron w/ O Neutral Charge = Proton w/ + + Positive Charge  Atom  The electrons of an atom are found orbiting the nucleus of the atom  Electrons have a negative charge  Structure of Atom http://www.ehs.utoronto.ca/services/radiation/radtraining/module1.htm  Phases of Matter  Matter is classified into four phases or states  Solid  Liquid  Gas  Plasma  Solid  Solids have definite:  Mass  Volume  Shape  Liquid  Liquids have definite  Mass  Volume  No definite shape.  Gas  Gases have NO definite  Mass  Volume  Shape  Plasma  Plasma is the form of matter that exists when the atoms are in an excited state.  Stars (the sun is a star) exist in the plasma state because of nuclear fusion.  Some examples of plasma found on Earth are: lightning, auroras, and neon. Plasma Video Review - Phases of Matter  Gases' shape is determined by container and volume is determined by container.  Liquids shape is determined by the container and has constant volume.  Solids have constant shape and volume. Cites  http://www.chem4kids.com/files/atom_structure.html  http://nobelprize.org/educational_games/physics/matter/1.html  http://education.jlab.org/beamsactivity/6thgrade/whatismatter/whatismatter.pdf  http://ecisst.net/Documents/UbD%20%20Properties%20of%20Matter%20-%20Lin%20an d%20Rosemarie.doc  http://staffweb.psdschools.org/jbarnaby/8_pwrpt/Matter%20Power %20point.ppt#270,15,Volume of rectangular solids  http://southwestgk12.tamu.edu/LessonPlans.asp?
