With the launch of the TREE program in the 2018/2019 school year, these are the schools from Ontario that have participated so far! You will find in these pages the data members of the Research Team have collected at CLS and MAD Lab for the participating school's tree and soil samples. You can also access the school's constructed timeline by clicking on the timeline icon and see their Data Summary Report in their corresponding folder. Take a look at the Sample Notes on each page, view the downloadable graphs, and compare to your own data! Want to explore the raw data? Access the group's folder and check our our instructions on how to create graphs on the Graphing XRF and XANES web page on our Virtual Classroom.
