Shared below are the outlines to our six Modules for the TREE program. These modules help support student learning and be sure to check out Module 2 for Timeline instructions and Module 4 for Sampling instructions. Also check out our Module Icon Guide, which covers the icons you will be seeing throughout the Modules.

TREE Module 1 covers tree anatomy, characteristics of trembling aspen, nutrient cycles, and more.

Topics addressed in this module include:

  • introducing general tree anatomy and functions,

  • identifying key characteristics of healthy and sick trembling aspen,

  • understanding the nutrient and water cycles of trembling aspen, and

  • understanding the various threats to, and their impacts on, trembling aspen.

TREE Module 2 provides timeline instructions and Indigenous connections to trembling aspen.

Topics addressed in this module include:

  • how trembling aspen contribute to human and wildlife communities;

  • place-based Indigenous stories, poems, and legends;

  • instructions on how students should construct their timeline that outlines potential environmental and human impacts affecting tree growth;

  • and Indigenous ecological knowledge of the territory.

TREE Module 3 provides content on what soil is, soil horizons, the nutrient cycle, and more.

Topics addressed in this module include:

  • introducing soil, identifying soil as distinct from dirt,

  • identifying the various types of soils and soil horizons, and

  • understanding soil formation and the nutrient cycle.

TREE Module 4 provides instructions on how to sample, how to collect tree cores, how to collect soil samples, and what is in the TREE kit.

Topics addressed in this module include:

  • what samples are needed for the TREE program,

  • how to collect the samples, what equipment to use,

  • how to use the equipment, and

  • how to package everything back up to the labs.

TREE Module 5 covers what the Mistik Askîwin Dendrochronology Lab (MAD Lab) is, what the Canadian Light Source is, and how the IDEAS Beamline is involved.

Topics addressed in this module include:

  • introducing the MAD Lab which specializes in dendrochronology and

  • the CLS team who specialize in elemental analysis and provide support for the TREE program with resources and activities.

TREE Module 6 covers the dendrochronology and synchrotron data schools receive from the TREE citizen science program.

Topics addressed in this module include:

  • examining tree rings and the wealth of information they hold,

  • insights into the elemental composition using XRF, and

  • how the labs will use the students’ constructed timeline to identify potential causes to trends in the data.
