Science 7 Biodiversity walk at AES Campus 15 & 16 October

Purposes of today’s walk:

  • To begin assessing biodiversity in the “field” on the AES campus
  • To discuss the idea of “search image”
  • To practice observation of living things in their environment
  • To practice orientation in the environment (directions, topography, watershed, vegetation cover, geology, soil, etc.)

The Art of Birding (note the 7 S’s–things to observe)

See these guidelines for observing a tree:

  1. Note the overall shape of each tree in words and sketches.
  2. Examine the leaves. Note the shape, size, number, and arrangement. Some leaves are compound—meaning small leaflets make up a single leaf. Some are doubly compound. What pattern is repeated?
  3. Examine any flowers and fruits. Note the shape, size, number, and arrangement of parts.
  4. Note the branching pattern.
  5. Note the bark. Make a bark rubbing if possible.
  6. Note any other spot characteristics. Smell of crushed leaves or scraped bark.
  7. Examine the trunk for its shape or other distinguishing characteristics.
  8. Names that you know or names that others know.
  9. Anecdotal information about the tree.
  10. Any other observations.

From looking at the guidelines for observing birds and trees, can you transfer the techniques to observing other living things (butterflies, ants, beetles, vines, shrubs, etc.)?
