Worksheet

• Changes of State when the Temperature Changes

Classroom Activities

• Experiment - Turning Solids to Liquids

  • melting chocolate

  • burning candles

  • melting ice

We melted candy coating to illustrate turning a solid into a liquid. Students then spread it on a graham cracker. When it cooled it turned back into a solid.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Identify characteristics of different types of mixtures.

• Definition of Mixture

  • blending two or more substances together in some random proportion without chemically changing the individual substances (You can separate a mixture by physical means.)

    • Examples

      • sand and salt

      • water and oil

• Definition of Solution

  • blending of substances in which one usually dissolves into the other (to separate a solution you use heat, evaporation, etc.)

    • Examples

      • Kool-Aid

      • seawater (salt and water)

       

• Online Activity Junkyard Analysis http://www.fossweb.com/modules3-6/MixturesandSolutions/index.html

• Activity

  Combine these substances and have students determine if they are solutions:

  • sugar and water

  • pepper and oil

  • mud and water

  • iron filings and sand

  Which method would you use to separate each?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Determine methods for separating mixtures.
