We are observing the leaf bud growth of three different tree species at three different locations and comparing the growth rate to the observed temperature.

Instructions / How to do this investigation

Question:

Which species of trees on the Woodside campus is the first to sprout leaves in the spring 2022 and what pattern do we see when compared to the temperature?

Materials:

  • Marking tape
  • Camera
  • Recording sheet
  • Tree identification sheet for New England

Plan:

  1. Identify three species of trees that grow leaves on the school campus.
  2. Identify at least 3 locations where the trees can be observed on the school campus.
  3. Mark three trees of each species at each location using string or tape.
  4. Mark a specific branch and bud to measure each week.
  5. Visit the area each week starting in March 2022.
