The Process
 

          1.  First you will be assigned to a group of three students.
        2.  Next you will define meteorological terms related to humidity using the internet.
        3.  The groups will be responsible for performing the "determining the relative humidity lab".
        4.  Groups will be given hypothetical conditions to determine relative humidity using table.
        5.  Questions over relative humidity will be answered by each group.
        6.  Graph the relative humidity findings for two weeks.
        7.  Write a report in which you compare a humid day with a non-humid day.
 

Evaluation

        You will graded on several items as a group during this webquest.   You will be graded on the definitions, lab, relative humidity problems,questions, graph, and report using a rubric chosen by the teacher.
 

Conclusion
 

        You have just completed a small fragment of a meteorologist's job.  Do you have a future in weather?
