Daily Objectives #3 (January 20, 2009)
end of today's class, you should be able to do the following:
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
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

GENERAL GUIDELINES FOR
TODAY'S LAB EXPLORATION:
- Bucket-to-Bucket Transfer
- Holey Water Bottle
- Draining Work
- Capillary Action
will come back to these later!
- Discover and articulate the general
principles that describe the movement of water and the factors that affect
- Quantify where you can.
- Draw diagrams or make graphs to
illustrate important points. (Graphs need not have precise measurements or
scalesójust 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!
