Investigating Earth Systems

Investigating Earth Systems (IES) is a standards-based, Earth science curriculum for the middle grades (6th-8th grades) developed by the American Geosciences Institute (AGI) in association with It's About Time Publishing. Field tested and content reviewed, IES is part of AGI's ongoing efforts at implementing effective Earth science education reform. AGI recognizes the need for students in the middle grades to have a solid understanding of the world they live in. IES was developed with generous support from the National Science Foundation (NSF) and AGI Foundation.
