Standard 1.5 - Use the periodic table as a model to analyze and interpret
evidence relating to physical and chemical properties to identify a sample
of matter.

1. Correctly place the physical properties of matter in the proper column in
the table below.

     a. Solid                       g. Good conductor
     b. Shiny                       h. Semiconductor
     c. Not shiny                   i. Gas
     d. Zig-zag line                j. Poor conductors
     e. Left side of table          k. Properties of metals and nonmetals

Standard 1.6 - Create and interpret models of substances whose atoms
represent the states of matter with respect to temperature and pressure.

1. Draw the particles of an element in a solid, liquid, and gas form:

Solid                      Liquid                    Gas

particles?

        a. Slow down                b. Get faster

3. As a gas goes to a liquid to solid, what happens to the speed of its
particles?

        a. Slow down                b. Get faster
