With the TREE Program, data is collected all across Canada. As more schools participate and we reach more provinces and territories, additional pages will be added. You will find in these pages the raw data the CLS and MAD Lab have collected from the schools that have sent in tree and soil samples as well as each school's constructed timeline. For instructions on how to create graphs from the raw data, check out the Graphing XRF and XANES web page on our Virtual Classroom. You can also download these instructions from our Files and Document section of the TREE website and check out the CLS YouTube channel for videos on how to create these graphs. The Research Team also provides constructed graphs of the data to help support student learning which can be found in the school's pages.
