Next, go to the following websites and follow directions.
The web sites below are specific to Florida's springs, but what is happening there truly parallels what we see happening here in Lawrence County.

Go to the Florida EPA web site link below; there are 10 separate links which detail threats to the Florida Springs. On a separate paper, (1)detail how each (yes, all of them!) threat can be seen happening here in Lawrence county, AND (2) what we can do about it.

Deep Trouble: Threats to Florida Spring's

I would like you to take a look at the link about Ichetucknee State Park. I've been there, done the tubing down the river trip (it was very, VERY nice!), AND I have also done water quality testing there. All the web sites listed have good practices as far as protecting the water and may give you ideas about how to answer # 2.

Good Neighbors....

This site may give you some more ideas about how to answer #2, especially if you are having difficulty answering it.

How to help" ideas....

Go to the following website, and the accompanying links, and make sure you check out all the links. And yes, I know some are broken links - I just didn't have time to hunt them all down again.

Christmas Break stuff


Go to the following website, follow the directions, and complete the research dealing with biomes.



Today you will be learning how to read seismograms - the records made by a seismometer of an earthquake that has occurred. This is a tutorial, so make sure you read the instructions on how to perform each part of the task in order to complete the assignment - don't just skip through and think you can just skip through it and figure it out on your own - you'll just waste valuable time.

Monday you will be working in-class for the final time on your posters. They are to be handed in on Friday the 20th.

Your test over chapter 3 will be Wednesday the 18th.

Now, click the following link for today's exercise and tutorial:


For today's assignment click on the following link:

Plate tectonics

When you finish, re-read the material about the posters (below) on 10/8/2009.

Today you need to research conservation and conservation programs to help you come up with a design for your posters. Below are a number of links to start you off, but you are not limited to just these links. If you have an idea for which you need images or just learn more about a particular aspect of conservation, then go ahead and search for it on Google.com.

I would like a sketch of your poster idea next week - to be turned in to me on Wednesday.

The following has numerous links which may help, and to which we will also be returning later.

Here's a link to the

Lawrence County Soil and Water Conservation District

If you click on the "Education link, there is information about the poster contest.

Lawrence County Soil and Water Conservation District Education page

This link is to the National website which has information about the contest, and also has images of previous national winners in each category. You might want to look at these for ideas about styles to use in your posters.

Don't forget to scroll down the page - there are .pdf files to read about it, as well as helpful suggestions.

National Association of Conservation Districts

This link is particulary good - it has links to other sites that will give you ideas about conservation methods, etc.

2010 Stewardship week link

This is related to conservation - ANY conservation related to helping provide healthy habitats is a good topic to use in your poster. Just make sure you visually link it to the topic - and remember, the poster MUST include the title: "Conservation Habits = Healthy Habitats "

NACD Stewardship and Education website

Make sure you click on and read the Stewardship section, and also the Educational resources links.

Clean Water Indiana

Are they all the same or not? Why or why not? Account for any differences.
Come up with at least 5 different reasons and write those down with your data.

Go to each of the following carbon calculator sites, enter your data, record the results, and compare all of them. Are they the same? What are some of the reasons they might not match up?

After you complete this, use your data to complete the graphing exercise to be handed in Friday.

3) 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.

Please hand in your answers at the end of the period.
