Daily Objectives #8 (February 5, 2009) Dr. Sanders

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

Review from last time

v Review: Using simple sketches, show how water would flow from one container (like a rain barrel) into another if they were connected by hoses.
v Review: Describe the relationship between capillary rise and pore diameter.
v Review: Define and draw a diagram illustrating the water table, capillary fringe, saturated zone, tension-saturated zone.
v If you are interested: For further reading on hysteresis, see these links: Link 1 Link 2 .

What makes water flow?

v Water Flow--Lab Explorations (continued from last time)

Darcy Discovery: Complete your investigation from last time, measuring the flow rate of water through various samples of sediment. We will compare values as a group.

v Using the ground water model ("sand tank"), inject colored dye and keep track of its flow over time. Observe the flow paths created by all the dye inputs. What makes water flow?
