LEAF PROJECT DUE 10/3/2014


Your leaf project consists of the following:
A) Collect leaves from 25 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) Include the following next to the leaf:
Name
Date collected
Location collected (address or lat/long coordinates)
List ALL the identifying characteristics used to identify the tree.
Your Name

When you finish, work on the study guide for your test. The test is tomorrow, and the study guide is due at the end of the period after the test.

Use GOOGLE CHROME to open the link below to go to today's website:

Footprint calculator



Read the material, then find YOUR carbon footprint in EACH of the following, making sure you enter the same data for each country/city which follows by using the footprint calculator.

Record ALL data which you enter on a separate paper in order to record the same data for each location. The data points are: 1) Ontario; 2) Ecuador; 3)Switzerland; 4)India; 5)Japan; 6) Australia.

For each location, list how many planets it takes to support YOUR lifestyle if everyone on Earth consumed as much as you.

Why do you think, that even though you used the same data, that your results would be affected just by using different locations? (Or are they affected at all?)


AFTER you finish the rest of the assignment...

Easter Island Investigation

Know these and follow the guidelines:
http://lsbailey.tripod.com/leafproject.html

(A) Read the instructions and follow them.

IF you do not finish with this today you must make other arrangements in order to do so. Today is the only day in the computer lab for this exercise, and it is likely you will not finish the exercise today if you want it to be quality work.

Go to the following website for an explanation of correlation and how it is used. Answer the questions which follow by reading the material found on the link.

Correlation explained...


Turn in your papers tomorrow or e-mail them to me by midnight Thursday.

1. What is correlation?

2. What is the purpose of a correlation?

3. What is a positive correlation?

4. What is a negative correlation?

5. Positive correlations will be reported as what?

6. Negative correlations will be reported as what?

7. In the following sequence, which number has the strongest results? .3; -.6; .6; .8; -.9

8. What are the advantages of the correlation method?

9. What are the disadvantages of the correlation method?

Click on the link at the page bottom - "Read a correlation sample."

Read through the two samples.

10. Of the two samples, which had the stronger correlation?

To find out how the number is calculated, click here:

Correlation calculation explained...



(B) Use the link below to go to the following website:

Footprint calculator



Read the material, then find your carbon footprint by using the footprint calculator.

11) How many planets does it take to support YOUR lifestyle if everyone on Earth consumed as much as you?

I hope this opened your eyes to a few environmental problems which we face. One person makes choices which can affect everyone. Think about what you do before you act.

12) Read through the links on the website below. It will help explain galls. And if you don't know what that is, it will come in handy on your test next week.

Read through the rules for this 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, August 22nd.


2015 Poster Contest


Pay attention to the links near the page bottom.("Other Useful Tools and Information for participants to design their posters.) Read through the links for tips about how to draw your poster.

8/13/2014

You are NOT to go to any website other than the ones found as links from this page!!!
Doing so may be cause for being removed from computer lab access.

# 4-8 are due today.

1) Due Monday:

Careers exercise



2) Remember, there is the probability of the class going outside in the next week, weather permitting. Make sure to dress appropriately.

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

*You need to place them in a folder - NOT a binder, unless it just takes up too much room.

4) From this point - Due at the end of the period TODAY.

Go to the following website for a tutorial on tree identification and click on "Click here to Launch the animation":

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?

What Tree Is It?



Here is one from Butler University - I think you will recognize it!
