Dendrochronology: Linking life and climate in the past part of Cutting Edge:Paleontology:Activities
In this exercise students explore; 1) how climate variables influence tree growth on historical and/or geological timescales, and 2) how climatic records are generated from biogenic chronologies. The exercise varies conceptually depending upon tree location (local and global), and type of tree records analyzed.
Geochemical Clues and Biological Insights: Characterizing the Importance of Salmon in Northwest Streams part of Curriculum for the Bioregion:Activities
Salmon streams in the Northwest are local field resources that can be used to demonstrate biogeochemical connectivity. In this series of exercises students become familiar with geochemical tools used to track the presence of marine (salmon) derived nutrients in the terrestrial and freshwater ecosystems of creeks where salmon spawn. They then use a reconnaiscence fieldtrip to design project proposals to charaterize the importance of salmon in a local creek. Students present their research proposals to a mock city council in response to downstream development pressure. Finally, students are given a take-home reading and questions that address the pros and cons of hatchery raised salmon in the Northwest.
