1. “Adopt A Tree” Project
Every tree is different! You will make observations and record data for your tree throughout the year and see how it changes

2. What makes a tree a tree? Heights at least 4.5 meters (about 15 feet)
Single dominant woody stem or trunk
Trunk is 9 1/2 inches in circumference (3 inches in diameter)
Definitely formed crown of foliage
Perennial plant

3. Abiotic Data
Date: ____________ Time:__________ Air Temperature: ___________ Relative Humidity: ___________ Rockaway Weather, Current Conditions and Temperature Weather Conditions: ___________________________________ (sunny, cloudy, rain, etc.) Light Conditions:______________________________________ (amount of light your tree receives at this time of day) List other abiotic factors: _______________________________ (water, rocks, and sand)

4. Draw a Picture (Draw a detailed picture of your tree
Draw a Picture (Draw a detailed picture of your tree. I should be able to pick your tree from the group just by your picture.)
When drawing your tree, start with the trunk and add just a few leaves. You don’t need to draw each leaf!!

5. Biotic Data
Tree Description: (Describe your tree in detail about 5-8 sentences. With this description, someone should be able to pick your tree out of the bunch.) List 5 Biotic Factors: (List all living things you see on and around your tree.) Leaf Description: Draw a picture of your leaf:

6. Draw a Site Map (Someone should be able to find your tree by looking at your map.)
Draw major features on your map.
Label your tree location
Draw symbols for other plant life. Example:
*Bushes
+Large Trees
∆Small Trees

7. Poison Ivy Leaves of three, let it be!!
Hairy vine, no friend of mine!!
Raggy rope, don’t be a dope!!
Berries white, run in fright

8. Poison Ivy

9. Be very careful!!

10. How should you behave when outside?
Don’t harm trees, animals, or insects.
Preserve the stone wall by walking around.
The quieter you are the more you will see
Stay Focused on assignment. You will be given a participation grade.
Be prepared to share your findings with the class!

12. “Fall” for Leaves in Science!

13. Dendrology ‘Dendro-’ from the Greek word meaning tree
‘-ology’ meaning the study of
Dendrology is the study of trees and includes taxonomy, identification, and ecology

14. Tree Identification
By observing leaves

15. Classes of Trees
Conifers (Evergreen)
Deciduous
Palms

16. Conifers vs. Deciduous
In the simplest sense there are two kinds of trees in the world.

17. Which is Which?

19. Characteristics of Conifers
Needle shaped leaves
Seeds that develop inside cones
Evergreen – green year round
Gymnosperm (“Naked Seed”) or Cones
Examples: pine, spruce, hemlock, fir

20. Examples of Conifers Balsam fir Red pine Douglas fir White pine
Fraser fir
Scotch pine

21. Conifer leaves
Scale like
Needle like

22. Conifer needles
Clusters
Singles

23. Deciduous Tree Characteristics
Broad flat leaves
Lose all leaves each year in the fall
Angiosperm (flowering plants), broadleaf, hardwood
Examples: oak, maple, beech, aspen, ash

24. Deciduous examples Red oak Elm Honey locust Red maple White birch
beech
Crimson king
Black locust

25. Leaf characteristics-deciduous
Leaf shape
Leaf arrangement
Leaf margin (edge)
Leaf type

26. Leaf Shape

27. Oval, Elliptical, or Egg Shaped??
Ovoal: Considerably longer than wide with almost parallel sides
Elliptical: wider at center and tapering to an equal size at each end.
Egg shaped

28. How do you ID a tree?
Examine leaf on tree-Pick one good example of leaf
Determine leaf arrangement-Draw picture in journal
Is the leaf simple or compound?
Observe type of fruit on tree
Use a dichotomous key to determine what type of tree it is!

29. Leaf Arrangement
alternate opposite whorled

31. Leaf Node
A leaf node is where the leaf is attached to the stem.  This way, a new set of leaves will grow from that area, which will make the tree fuller.

32. What is this type of leaf arrangement?

41. Leaf Margin (Edge) Lobed , smooth, toothed (serrated)?

42. Serrate or Doubly Serrate? Write definitions below on Lab
Smooth
Wavy
serrate — a leaf margin that has pointed teeth that are directed upward
doubly serrate — a serrate leaf margin where the primary teeth support another set of teeth

43. Serrate or Doubly Serrate?

44. Serrate or Doubly Serrate?

45. Serrate or Doubly Serrate?

46. Serrate or Doubly Serrate?

47. Types of Leaves Simple: Has only one leaf per stem.
Compound: Has more than one leaves per stem.

48. Simple Compound Only one leaflet Joined by its stalk to the woody stem
Examples: maple, oak, aspen, beech
Made up of several leaflets
Leaflets are joined to a midrib that is not woody
Examples: ash, walnut, sumac

49. Simple or Compound?
Simple Leaves
Compound Leaves

51. Leaf Observations Deciduous Conifer Leaf arrangement:
Alternate, opposite, whorl
Needles or scales
Leaf type:
Simple, compound
Needle attachment:
Single, clusters

52. Don’t Be Fooled!!
A few plants will try to fool you by having opposite leaves in some places, and alternate leaves in others. So look at a few parts of the plant. Always examine many samples in nature, to get a good understanding of what ís going on.

53. Why do Deciduous Trees’ Leaves Change Color and Fall Off in Autumn?

54. You Don’t Have to, You Get To!!
Guess what??? Now you are ready to go on our leaf walk and start collecting our leaves for your own leaf collection. We have a lot of fun and don’t worry, we collect almost all of the leaves together!

55. How do I Put the Collection Together?
Keep all of your leaves pressed for at least one full week.
Take your leaf title pages you made in computers and carefully tape or gluestick your leaf to each page.
Place your leaf pages in number order, either with a 3 hole punch or by sliding them back to back in the protector pockets.
Create your own cover stating “Leaf Collection” and your first and last name. You may use the computer or you may use any craft materials to create a fancy look.
Put the following pages in order to complete your notebook:

56. Please put your notebook in the following order:
Table of Contents
28 leaf samples pressed and labeled
Poems about Trees (neatly written, illustrated, and colored)
Tree Outline
Tree Terms Sheet
Outline Test
Leaf Identification Test

57. What do the Pages Look Like?
