Matter Adapted from: Ms. Avery
Vocabulary Matter: anything that takes up space and has mass http://learningchemistryeasily.blogspot.com/2013/06/the-science-of-matter.html
States of Matter Kinetic theory of matter: All particles of matter are constantly moving Solid: particles close together Slowly shaking Liquids: particles still close together but not in fixed positions Gases: particles spread out
Changing States Caused by temperature change and kinetic energy change Temperature and Kinetic Energy Rise: Solid to Liquid: Melting https://www.flickr.com/photos/stevendepolo/3762687310/ Liquid to Gas: Evaporation http://www.extension.org/pages/68213/what-is-water-evaporation#.VDsKWPldVb0 h
Changing States Temperature and Kinetic Energy Lower: Gas to Liquid: Condensation Liquid to Solid: Freezing

The Phases
Scientists who discovered the Atom Dalton- atom Crookes- negative particles Thompson- electrons and protons (atoms have no charge) Rutherford- nucleus, electron cloud, and neutrons Bohr- electron energy levels
