how CLEAN reviews teaching materials
Teaching Tips | Science | Pedagogy |
- Could be used in a biology or Earth science class.
- Educators can bring out the scientific method and how it is being applied to study past, present, and future.
About the Science
- Dr. Ward studies how rising levels of carbon dioxide in the atmosphere may be impacting trees around the world, and even causing them to adapt. By looking at tree specimens from the Ice Age, Ward is able to see how trees in the past have adapted, helping her to understand how trees may adapt today and in the future.
- Comment from expert scientist: Good explanation of the techniques used in this form of chrono-analysis of tree rings, capturing the genetic component as well. Also goes into why CO2 might have a strong influence on tree populations - a good concept to include.
- Passed initial science review - expert science review pending.
About the Pedagogy
- This video can be embedded into a discussion about paleoclimatology and how it is done, but most importantly how species' adaptations in the past can help scientists to predict their ability to adapt in the future.
