    2nd Day of Boot Camp

    You have been doing a really good job of boot camp so far!!! Pay attention to detail on your TAKS type questions. We will be continuing with our vacabulary words and our TAKS type questions. Today's review will center around physical and chemical changes. This has to do with chemistry and parts of the erosion process (chemical and mechanical or physical weathering). Look over the list of chemical and physical properties. It is these properties that help arrange the elements in the periodic table.
    Chemical :Flammability (burning), Reactivity, Rusting or Oxidation
    Physical: Ductility (put in a wire form), Conduction ( a conductor moves heat easily), State of Matter (solid, liquid or gas),
    Density, Size, Mass, Melting Point, Boiling Point, Color, Luster (shiny), Malleability (flattened).
    Also in a chemical reaction you have reactants and products.
    NaO + HOH (reactants) Yields(there should be an arrow here) NaOH (product) Reactants (left) are what you start with and Products (right) are what you finish with.
    To review phases or states of matter go to www.chem4kids.com/files/matter_changes.html .
    Solids - particles are really close together. Liquids - they are a bit farther apart. Gases - particles are spread out.
