Teaching Tips | Science | Pedagogy |
- Can be done in a homework or lab environment.
- This is a challenging activity with solid science and practical advice on how to use the sediment cores. To do well, it will take 3 to 4 class periods with some homework assignments and require the educator to take time to familiarize her/himself thoroughly with the background material.
About the Science
- Resource provides a set of activities using detailed data and extensive background material, from high-quality scientific papers, on how to collect and analyze scientific data and samples from deep-sea cores.
- Part 1 activity data on the composite stable isotope records of oxygen and carbon in deep-sea benthic foraminifers (from the Cenozoic Era - 65 million years ago to present - and the last 5 million years) and on the physical properties of sediment cores are taken from recent research papers and reports. Part 2 focuses on shore-based data and analysis of fossil samples collected from around the time of the Paleocene-Eocene Thermal Maximum (PETM), 55 million years ago.
- Several diagrams in the section on the Milankovitch cycles are taken from WikiPedia without clear attribution or explanation. More information is available at http://en.wikipedia.org/wiki/File:Milankovitch_Variations.png.
About the Pedagogy
- Resource is suited to a college-level audience; likely difficult to use in a high school context.
- Students examine real data from sea floor cores to find physical evidence for the Paleocene/Eocene Thermal Maximum (PETM), 55.8 million years ago. Students then use shore-based data, including carbonate content and carbon isotope ratios and benthic oxygen isotope ratios, from 9 different sites around the world to examine the differences between planktic foraminifera and benthic foraminifera around the PETM.
- Only one of the six parts of the activity involves active learning and observation; the other parts give challenging worksheet-style questions covering important topics.
- Scaffolding is minimal but suitable for college level.
- This resource engages students in using scientific data.

Technical Details/Ease of Use
- Outline of activity might be a little confusing with each of the six lessons in a separate PDF document and no clear connections between the individual activities.
- Articles in this resource are highly technical with a lot of specialized language. Only educators with background in this material will be able to present it effectively.
- There is no instructor's guide.
