Elementary

1. "Matter can be changed from one state to another and then back again. This may be caused by heating and cooling."
   1. BBC Science: Changing State
      This site allows children to explore the differences between a solid and liquid change of state in water. A quiz is included.
   2. BBC Science: Gases Around Us
      This site allows children to explore the concepts of evaporation and condensation interactively. Another page gives children the chance to identify common objects as solids, liquids, or gases.
   3. BBC Science: Reversible and Irreversible Changes
      This site allows students to investigate reversible and irreversible changes in matter. It includes melting, freezing, mixing, and seperating several substances into component parts.
   4. BBC Science: Solids and Liquids
      This site gives students the chance to find the boiling point and room temperatures of various objects. A quiz is included.
   5. Brain Pop - States of Matter
      Students can view a movie and/or take an interactive quiz on States of Matter.
   6. Chem4Kids
      This site provides links to information about changes in matter that address this expectation, but it offers other sites with excellent information in the chemistry and biochemistry areas. Although it is not interactive, it presents the information in an interesting and colorful way.
   7. Phases of Matter
      This site shows the change in motion of molecules in three different materials as the temperature changes. It shows the temperature of the material and the corresponding state of each material.
   8. ReviseWise Science: Solids, Liquids, and Gases
      Great. This site that allows the students to click through animated information windows that teach the basics of the three states of matter. Tests and worksheets for the activity as also available.
   9. ReviseWise Science: Changes in Matter
      This is a great site that allows the students to click through animated information windows that teach the basics of changes in matter. Tests and worksheets for the activity as also available.
   10. Science Bob Experiments: Rock Candy
       An activity/experiment that dissolves sugar in hot water and forms edible crystals on a paper clip. Includes discussion of saturated solutions and precipitation. Requires adult supervision because of hot water.
