required: pictures of wetlands and wetland animals and plants, sponges,
cotton swabs, toothpicks, pine needles, pine cones, etc, glue, markers,
scissors, cardboard, modeling clay, rasting pan, disposable plastic tray,
a jar with muddy water.
time is probably about 15 - 20 minutes.
activity is appropriate for all ages.
entire afternoon visit (1 hour) is good for this activity.
This may work best if the kids are divided up into small groups, each with
a WOODS supervisor. To construct the wetland, complete the following:
spread clay over half of pan, this represents land (make sure it slopes
towards the "water")
litter it with pine cones and needles, cotton, etc, to represent vegetation,
and etch in little streams
cut a piece of sponge to fit along the edge of the clay land, which will
represent the wetland
Now, pour some water over the environment, and watch how much mud makes
it to the "water". Then, remove the sponge, the wetland, and pour more
muddy water and make the same observation.
Discuss this thoroughly with the kids - why did we represent the wetland
with a sponge?
