The Carbon TIME (CTIME) project is a collaboration of scientists, teachers, graduate
students, and IT specialists with the overall arching goal to refine current K-12 frameworks
and assessments for learning progressions that lead to environmental science literacy.
Given the above, we have developed a series of six teaching modules
that can be used at the middle school or high school level. Each of these learning modules are nested within this
website along with assessments for each learning module.
