Assignment for 8/26/2015



LEAF PROJECT INFORMATION
(Questions below!)

1) Your leaf project consists of the following:
A) Collect leaves from 20 different trees (there must be no two leaves from the same species of tree)

B) Press them: this may be done by placing a paper towel or newspaper onto a flat surface, laying the leaves on top, then placing something like magazines or books on top of the leaves for a couple of days. The leaf will dry out and will have been pressed flat.

C) Mount the leaves on paper, one leaf per sheet unless the leaves are small enough not to be crowded - construction paper or notebook paper will suffice - using tape. If the leaf happens to be too large or long for one sheet, tape two together and then mount the leaf onto the paper.

D) Your name and class period must be on the front of the folder/binder in which you hand in the collection. (you can print it on tape stuck to the front if you so desire)

Include the following on the sheet next to the leaf:
Name of the tree
Date collected
Location collected (address or lat/long coordinates)
List ALL the identifying characteristics you used to identify the tree.
Your Name


Go through the next 3 links and read about the leaf parts and familiarize yourself with them - well enough to be able to use the terminology. This is critical in identifying leaves you collect for your project. You will have a quiz (Identify the part when shown a picture or drawing of the part) over the parts listed below near the end of next week (Thursday or Friday):
(all of these may be found on the Butler University link)

A) Base
B)Stalk, or petiole
C) Lamina or leaf blade
D) Simple leaf
E) Compound leaf
F) Leafstalk
G) Bud
H) Stem
I) Leaflet
J) Leaf arrangement (Alternate or compound)
K) Margin (entire, singly-toothed, doubly toothed, lobed, leaf clasps)
L) Palmate, Pinnate, Doubly-compound
M) Fruits, berries, cones, catkins, pods, nuts, seeds with wings.

Tree Identification Links:
1.
Butler University article on tree parts.



2.
About.com article on tree parts



3.
Homestead.com Tree Tutorial.


4)

From this point - to be completed by the end of the period TODAY.


Go to the following website for a tutorial on tree identification; work your way through the exercise:

Arborday.org


5) Proceed through the exercise on tree identification which pops up when you click the link above. It's simple, but it may save you some grief when identifying your tree leaves. Taking notes would be good.


6) The link which follows has a nice online tree identification application. Click through it, and see what you can do with it using the following information: Broadleaf, with the leaves being rough on top; Red to Dark purple fruit; Simple; Alternate; Not fan shaped; Toothed; both lobed and unlobed on the same tree. What is your answer?

What Tree Is This?


7)Here is a different tree guide:

The Basics of Tree Identification

Click on each of the links listed under "Clues that you will need to examine", and review each. Make sure you click through each page for each link too - the leaf link has 5 pages. It would be a good idea to take notes on each characteristic while you are looking at the page - it may prove to be the difference between getting a leaf identified correctly, or incorrectly. Note that there is an app for smart phones available on this website.

8) Click on the "Leaf Key" link, and try to identify the tree I'm describing: Simple, lobed, pointed broadleaves with a finely cerrated margin are shaped like a 5 pointed star. It has long leaf stems, arranged alternately on the twigs. The fruit is a spiny ball, and the tree generally grows in low, wet woods.


Use the characteristics listed above with the following key. Did you get the same answer?

Trees from the list found on the link below do not match the list in your packet - use ONLY the leaves listed in your packet, plus the Northern Catalpa, to collect specimens.

***Read through the rules for the following contest and start researching about the topic to get background for ideas to use in creating YOUR poster. You are NOT to use the logo for the contest, and material must be original work. (Originality is a plus - the more different your poster while addressing the topic, the better!) Posterboard will be supplied, and the poster handed in by early November; I would like a rough draft (on notebook paper is fine) of what you will be making by Friday, September 4th.
