how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy |
- The resource includes extensive teaching tips on its webpage.
- Video can be used as a hook at the beginning of a lesson about paleoclimatology but should not be used to illustrate the science of diatoms.
About the Science
- To test the idea that eastern Africa had undergone rapid swings in climate - from wet to dry to wet again - over a period that began 10 million years ago, German scientists study fossils of tiny one-celled aquatic organisms called diatoms.
- The layers of diatom fossils in eastern African rock formations suggest that this part of Africa experienced wet and dry periods over time, supporting a new idea that climatic variability may have shaped human evolution.
About the Pedagogy
- The short video gives a good example of how scientists use fossil evidence to develop climate reconstruction for a region.
- The video includes a background essay, discussion questions, teaching tips and connections to standards.
