The river is the central theme that binds together six teacher resource books -- and six content areas -- in this interdisciplinary high school curriculum. Students learn to work together to make a difference in their own community while exploring vital topics. The Rivers Curriculum units work together to form a complete, interdisciplinary program or stand alone as supplements to your existing curriculum. Each comprehensive teacher resource includes a variety of field and classroom activities, teacher support materials, journal, portfolio, and other assessment components, and blackline masters.Monitoring the variety and changes among living organisms in a stream.
