  1. So, what’s the deal with pine needles? Genevieve Chung Ethel Stanley Susan Finazzo

  2. Why use plants as models for data collection? • Plants are everywhere familiar • Students ‘see’ them without seeing them. • Plants respond to the environment, both macroscopically and microscopically. • You probably won’t have PETA knocking your door down.

  3. Why do pines? • Common plants • Background info available • Perennial evergreens have ‘history’. • Tree leaves exist in microenvironments.

  4. Student Generated Data • Student develop hypotheses (re:leaves). • Directional differences (east facing vs. west facing) • Age factors • Canopy location • Different tree data, irrigated vs. non-irrigated • So many questions, so little time…..

  5. Our Data • East and West Branches • This year’s and last year’s growth • Number of fasicles • Length of fasicles • Wet weight • Dry weight

  6. Data Presentation with Merlin • Sample 1 • East side • 15 fasicles, 2009 • Sample 2 • West side • 48 fasicles, 2009 • Sample 3 • East side • 30 fasicles, 2010 • Sample 4 • West side • 32 fasicles, 2010 • Sample 5 • East side, main branch • 66 fasicles, 2009 • Sample 6 • West side, main branch • 84 fasicles, 2009
