Daily Objectives #5 (September 11, 2007)                                        Dr. Sanders

By the end of today's class, you should be able to do the following:

v Water Flow: 
  • Describe in words what makes water flow. 
  • Using simple sketches, show how water would flow from one container (like a rain barrel) into another if they were connected by hoses.
  • Using simple sketches, show how water would flow from a container filled with saturated sand to another filled with saturated sand if they were connected by hoses.
  • Explain what would make water flow from one portion of a saturated porous medium (e.g. a unit of saturated sand) to another portion of the same body of saturated material.

v Making a Scientific Presentation:
  • Organize and verbally convey information on a scientific lab experiment to an audience , supplementing your talk with simple illustrations.

Today's Agenda:

v
Debriefing the last weeks' activitiesDiscuss the meaning/importance/concepts of the rain barrel exercise and the exercise on water levels in wells.

v
Ground Water Model (continued from last week):  Using the ground water flow model, sketch a diagram showing the following features:    
    q
surface water
               
q    ground water
    q boundaries of the flow system
    q flow directions (use arrows)
    q flow velocities (show areas of fast/medium/slow flow)

v Water Flow--Lab Explorations (continued from last week): Investigate, discover, and articulate the general principles that describe the movement of water and the factors that drive it.  Use simple lab set-ups to investigate the movement of water through open conduits and through porous media. 

Activities for today (Click here for an MSWord copy of the instructions
):
Present your work for one of the activities.  (We will split them up to make sure all activities are covered.)  In your brief (2-3 minutes) presentation, please convey to the audience information on your experimental setup, your results (they may be numbers, graphs, or verbal observations), and at least one conclusion based on your experimental results.

GENERAL GUIDELINES FOR TODAY'S LAB EXPLORATION:
