Late in 2000, the first version of the high school curriculum Life in Our Watershed: Investigating Streams & Water Quality was co-authored by Greg Suba and Eva Butler with support from the Splash team. It was reissued in 2005 as Version 2. Version 3, which features a new Student Handbook and Teacher's Manual, was issued in April 2009 as the Splash Secondary Curriculum for use in middle schools and high schools.
