Erosion Threatens Your
Community!!!!
4th
and 5th graders: Professor Keepsoil needs
your help…
|
Students: Your community is very excited
about the new shopping center to be put up in the middle of town. Mayor
Washout keeps talking about all the stores and food places it will offer. It
seems as though everyone would rather listen to him than to Professor Keepsoil who insists that the tearing down of trees and
the paving over of the soil will ruin the town because of the erosion it will
cause. |
|
|
|
Your Task: Make Professor Keepsoil a poster that can be displayed around town that
will help him reach the community with his points about the affects of
erosion. Be sure to include what causes erosion, especially when trees are
removed and soil is taken away. Also include what affects erosion might have
on the town. Professor Keepsoil is having trouble
getting people to listen to him so make sure your poster stands out. |

A
good place to start your thinking about erosion is to take notes on the
following questions:
|
|
Once you answer these you will
be an expert on erosion and prepared to inform your community. Erosion
affects different types of communities in different ways. Feel free to be
creative in what your community is like (e.g. mountainous, desert, swamp,
etc.) Just make sure the points you make on your poster are relevant to the
community you imagine you are addressing. |
