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.
- Explain
what would make water flow from
one portion of a saturated porous medium (e.g. sand with water in it)
to another portion of the same medium.
Today's
Agenda:
v Ground Water Model:
Using
the ground water flow model, inject dye into the model and track its
flow through time. 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: 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):
- Bucket-to-Bucket
Transfer
- Holey
Water Bottle
- Draining
Work
GENERAL
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
something new?
- 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
results.
- Have fun!
