This episode comes with a hands-on Learn-Along guide which meets and cites US educational content standards for use in the classroom.
Dr. Peter M. Brown takes core samples from trees to analyze their age, but we learn much more than that when we study its rings. Scientists can tell a lot about climate, fires, and even human or animal scarring. Tree Rings are nature’s notebooks, documenting the events of the years and storing that information in the libraries of their trunks.
Some trees are older than others, yet do not look as old as they really are. Bristlecone pines are the oldest trees on record, dating back more than 5000 years. But in another episode of The Children’s Hour called Forests, we learn that some seemingly small creasote “bushes” are actually more than 10,000 year old trees.
That’s a photo of a bristlecone pine tree, located in the southwestern deserts of the United States. Learn a lot more about dendrochronology in our Learn-Along Guide that meets and cites US National education standards. Our Learn-Along guide includes even more information, links, and activities to better understand dendrochronology.
This episode was produced by Katie Stone, our Executive Producer and our Senior Producer, Christina Stella, with live engineering by Chad Scheer. Our Learn-Along Guides are written by Jonathan Dunski. Many thanks to Dr. Peter M. Brown for providing so many additional resources for us to share with our listeners.
