1.     What happens to the molecules of liquid water when it boils?  Have you ever boiled water before?  If so, what for?  How would you describe the energy of the water before boiling and after boiling?
     2.  Explain the difference between boiling and evaporation.  How are boiling and evaporation similar?

    3. What is the boiling point of water in Fahrenheit (°F) and Celsius (°C)?

    4. What is the melting point of rock?  What is the melting point of water?
    5.  What happens to water molecules when they freeze into a solid?  Have you ever witnessed water changing from a liquid to a solid?  How would you describe the energy of the water before and after it froze?

    6.  At the 2:00 mark, estimate the volume of the liquid in the beaker, don’t forget units!
