Leopold Education Project (activities)

The Leopold Education Project (LEP) deals with Part I of The
Sand County Almanac, which records observations and events
throughout the seasons. Although the over-riding purpose of the
lessons is to promote responsible decision making regarding our
impact on ecosystems, the developers do not advocate particular
positions on value-sensitive issues such as hunting, using
wetlands, applying pesticides and herbicides, or any others. The
LEPs underlying theory about these controversial topics is that
given a supportive classroom climate to study a variety of
positions and viewpoints, students will develop responsible
environmental values on their own. |
