Notes From Our Reviewers
The CLEAN collection is hand-picked and rigorously reviewed for scientific accuracy and classroom effectiveness.

how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy |
- The video can be used in a variety of ways and contexts, such as Geography, Asian History, Asian Culture, or Environmental Studies, or in a class where research methods for the reconstruction of past climates are taught.
- CLEAN collection offers good hands-on activities to learn more about the study of tree rings (dendroclimatology/dendrochronology) to examine past climates.
- The video is somewhat long - 8.5 minutes - so instructors may want to provide questions to follow along with the video to ensure students view the entire segment.
About the Science
- In order to understand the past history of monsoons, scientists take tree cores to determine when monsoons and dry periods have occurred in Asia from 1300 to present.
- The process of sampling trees for dendrochronology is shown very well.
- The explanations of the monsoon and its impact on local weather conditions are summarized in the spoken text.
- Supporting diagrams shown in the video are not always directly connected to the context of the narration.
- Passed initial science review - expert science review pending.
About the Pedagogy
- The video is easy to understand and important science concepts are illustrated in a variety of ways (i.e. pictures, diagrams, and graphs).
- The video shows how the tree rings suggest that droughts appearing in early Asian history lasted 30 to 50 years.
- These findings coincide with the decline of some Asian societies. The cause of these declines may now be attributed to these drought conditions, which illustrates how dendrochronology can be used to help us understand the past.
- Other tree readings indicating climate change were corroborated by local written records.
