Radiocarbon calibration part of Vignettes:Vignette Collection
Radiocarbon dating is one of the most reliable and well-established methods for dating the Holocene and Late Pleistocene. Natural radiocarbon or 14C is produced in the atmosphere by the interaction of the secondary ...

The Impacts of Climate Change on x̌əpayac (Western Redcedar) and the Social Justice Implications for Indigenous Culture part of Curriculum for the Bioregion:Activities
Students use botany to explore how cedar trees are affected by climate change and the cultural importance of these trees to local indigenous peoples. As part of a field-based laboratory experience, students participate in a citizen science project that involves collecting data about cedar trees. The activity ends with a civic engagement experience designed and carried out by students to demonstrate how scientists can share their work with the public and with policymakers to address issues of concern to society.
