-Offers an interdisciplinary, three-lesson module using project- and problem-based learning to help ninth-grade students investigate different epochs and time periods of the Earth’s formation.

-Written and developed for ninth grade teachers, the book offers lesson plans guiding students to identify, define and describe the attributes scientists use to delineate Earth’s eras, periods, and epochs, in order to determine the appropriate boundary event to define the Anthropocene Epoch, and to develop a publication-ready textbook entry for an Earth science textbook.

-Anchored in the Next Generation Science Standards, the Common Core State Standards, and the Framework for 21st Century Learning, which can be used in full or in part to meet the needs of districts, schools and teachers charting a course toward an integrated STEM approach.
