To Err Was Dirty to Repair Takes Time How We've Cleaned Up Our Act
An Integrated, Interdisciplinary Thematic Unit for 8th Grade on Conservation from the 1930's to the Present This integrated/interdisciplinary thematic 8th grade unit is important because our earth is weathering away and unless we make definite changes in our conservation practices, we will be limited in all we have and do. Through an examination of soil conservation practices and air pollution problems, the students will be able to make more informed decisions now and in the future.
