Daily Objectives #5 (September 11,
the end of today's class, you
should be able to do the following:
v Water Flow:
what makes water flow.
simple sketches, show how
would flow from one container (like a rain barrel) into another if
were connected by hoses.
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.
what would make water flow from
one portion of a saturated porous medium (e.g. a unit of saturated
to another portion of the same body of saturated material.
v Making a Scientific Presentation:
and verbally convey information on a scientific lab experiment to an
audience , supplementing your talk with simple illustrations.
v Debriefing the last weeks' activities:
meaning/importance/concepts of the rain barrel exercise and the
exercise on water levels in wells.
v Ground Water Model (continued from last
the ground water flow model, sketch a diagram showing the following
q surface water
q boundaries of the
q flow directions (use
q flow velocities (show
areas of fast/medium/slow flow)
v Water Flow--Lab Explorations (continued
from last week): Investigate,
articulate the general principles that describe the movement of water
factors that drive it. Use simple
lab set-ups to
investigate the movement of water through open conduits and through
here for an MSWord copy of the instructions):
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
setup, your results (they may be numbers, graphs, or verbal
observations), and at least one conclusion based on your
- Darcy Discovery (we'll
do this one some other day)
GUIDELINES FOR TODAY'S LAB EXPLORATION:
- Discover and articulate the general
principles that describe the movement of water and the factors that
affect its movement.
- Quantify where you can.
- Draw diagrams or make graphs
to illustrate important points. (Graphs need not have precise
measurements or scales—just show general trends.)
- Use your imagination and
creativity! Can you alter the exploration a little to discover
- If you decide you want to use
other materials, or you have an idea for improving the experiment,
please ask, as we have a whole lab at our disposal.
- Clean up after you finish so
that the next group will be able to work.
- Be prepared to present your
- Have fun!
