Clues to Past Environments is a three day lesson culminating with a kinesthetic activity. It is part of a larger unit plan Change and Earth’s History. The three day lesson is organized with specific details including a teacher’s guide. This includes an overview and background information. Three additional appendices include lecture notes, a student lab page, teacher “core sample”with photos and a detailed description of the kinesthetic activity. In the kinesthetic activity small groups of students will create “core samples”.Collaborating within their small group, each student will draw a corresponding stratigraphic column, which will include interpretation of the paleoenvironments represented with possible explanations of why the environments changed. Given stratigraphic columns, other groups will try to match cores with columns. An assessment activity is not specifically designed but a core/drawing matching activity and a class presentation of the core sample could be an assessment.
