  2. Engagement • Engagement: Walk the school grounds and make general observations about the trees; collect qualitative and quantitative data. • Let’s consider the issue of plant health and diversity? • Look for evidence of ‘characteristics of life’ • Look on and off campus • Other Options • Map the landscape from above • Collect acorn caps (a favor)

  3. Exploration • Walk the grounds and collect data on each specific tree (whole grounds or an area of school grounds) • Collect leaf rubbings (whole leaf to petiole) and data on each tree

  4. Explanation • On white boards, compare your leaf rubbing data; use the electronic resource to create logical groups for your leaf data. • Use the resource given to learn about leaf parts and create a small taxonomic key on the samples provided

  5. Elaboration • Create a taxonomic (dichotomous) key that can be used to identify the leaves given • Challenge: include some of your own leaves to the mix

  6. Evaluation • Use ataxonomic (dichotomous) key to identify trees in the area or at a park • Add tree species from home to the taxonomic (dichotomous) key • Make a statement about the diversity of life on the campus regarding trees
