permeability, percentages, maybe
|
| Approximate Grade
Range: |
8th - 10th ?
|
| Materials: |
3 strainers, 3 different kinds
of dirt, 3 plastic containers, measuring cup, ruler
|
| The General Idea:
|
Students will find out that
different kinds of soil retain water to different degrees. Talk
with the students about different kinds of soil and what plants need
for growth. Lead students to make predictions about how each kind
of soil allows water to pass through or retains water. Get the
dirt. Fill each of your strainers with a different kind of dirt
(e.g., sandy, compost, dirt from the playground, etc.) and sit them on
the plastic containers. Pour 1 cup of water through the soil and
into the plastic container. After some period of time (1 minute?
2minutes?) measure the amount of water that ran through and determine
how much was retained. try it again when the soil is wet.
How does retention change?
