  ANNOUNCEMENTS    scroll down for earlier announcements/ information
13 Dec     Important correction!  Please note that I made a mistake on the syllabus/schedule online, and it shows our exam time as
7:00 pm on Wednesday.  I have no idea how I managed to not correct this before now, but the exam time, according to the published exam schedule, is at 6:00 - 7:50 pm.  This is a problem, because the class that meets after ours during the semester will need that classroom at 8:00 pm.  Please check your email for a message from me, and respond to confirm that you received this information.
Thanks for your understanding!
6 Dec     I'm sorry not to realize my error: I had two different deadlines posted for the final project.  In order to be the most fair to the students, I have changed the deadline to the latter of the two dates.  The wiki has been updated to reflect the changed due date.
If you have already posted your project, according to the earlier date -- (1) good for you! it means you're done!  OR  (2) If you still want to "tweak" it - you can upload an edited version, up to the later deadline.  PLEASE NOTE:   NO project will be accepted if it is not uploaded to the wiki by the deadline!!
7 Dec - clarification regarding last homework assignment...  I deliberately made it due *after* class - with enough time for those of you who might have another class after ours - so that (if you want) you can consider what is covered tonight in class before responding to the questions.  Of course, if you have already turned it in, or if you want to turn it in, before class today: that is fine!

14 Nov
Final deadline for selecting a term project topic is Monday, 21 Nov.  If you have not yet tried to access the course wiki, and the project information, you should do so immediately!!  (read the announcement below - 6 Oct - for important introductory information to the project.)
Also:  Wednesday, 23 November - there will be no class on this date.  Consider it a chance to work on your term project!
There will be a new homework assignment posted soon, to be due on Monday, 21 Nov.  Stay tuned to the assignment page for details...
6 October      intro to term project;  read this first!
The class Wiki is up and running, and is ready for you to sign up for a project topic and read all the project details.

You will need to sign on to the wiki, and check that you have full access to the editing functions.  In order to do that, you will need to do the following:
If you have any problems accessing the wiki, or with other aspects of this project, send me an email or talk to me after class, and we will sort it out.

1.  If you already have a google account, go to step 2.  If you do not have a google account, you first need to create one, as follows: 
Go to; click on "sign in" (top right); then click "sign up for a new account" (at the top).  Follow the instructions; then, check your email for a confirmation from google (be sure to check your spam folder if you don't see an email!).  When you receive the confirmation email, follow those instructions to complete the process of creating your account.  Keep track of your password!  Forgetting your password is the number one trouble that people have with logging in to the wiki!!!

2.  Send me an email, from the account that you used to create your google account.  As the subject, please use "ESCI 123 wiki account".  I will add your email address as a collaborator for the google site.   Send the email to my NEIU email address!  And identify yourself by name in the email!

3. After I have added your email address as a collaborator for the wiki, you will receive an email notification that you have been added.  Click on the link in that email: it will take you to the log-in page for google sites.  (If you are using neiu email, right-click the link and choose "open in new window".  For some reason, this makes a difference!)
If you have not received an email invitation to the wiki, it is because you have not yet sent me an email (see step 2)- you should do this immediately!

4.  The wiki page will appear and, after you have signed in**, you should see a box at the top right labeled  "edit page".  If the wiki page loads without a sign-in page, scroll to the bottom of the wiki page, and click "sign in" -- at the left of the (small) menu at the bottom.   If you are on the wiki page and are signed in, but still do not see the "edit page", let me know.   **After clicking the link to go to the wiki page, look for your user name at the top right.  If it is not there, you are not yet signed in.  Scroll down: at the bottom of the page, there is a (small!) menu list.  Click on "sign in", and open your google account.  You should now see your user name and the edit box at the top.

5.  Information about the project is on the home page of the wiki.  At the upper left of the home page are links to the other wiki pages, including "topics" - where you will sign up for your project topic.  Please note that if someone else has already signed up for the same topic, you will need to pick something different!

6.  Along the way, if you need help on any aspect, including how to choose a topic, how to create the desired format for your project, or other aspects of your project, I would be happy to consult with you!

7.  When you complete your project, it will be submitted via the wiki: you will upload your completed project to the "Project Documents" page.  Your classmates' projects will be there, too: hopefully you will take a little time to browse the information that they provide! 

A rubric for the final project is available here: use it as your "check list" as you work on your project!


As promised today, before the exam:   
There is an assignment due on Wednesday!!  (It's a short one.)  Remember to check the assignments page for details.
Complete the volcano worksheet that we started in class on Wednesday (28 Sep): turn it in on Monday, 3 October before the exam.
See the "Resources and Links" section at top of class homepage for some resources; and also the following:
               geotectonic environments:  map1    map2                         q. 4: the additional site to consider              
 Please note that, if MS Word or Open Office are not workable formats for you to submit assignments, you may use pdf format.

As demonstrated in the last couple of class sessions, the assignments have been migrated to their own page.  Click the link at the top of this page to find all the information you need...

WELCOME to ESCI 123 in FALL 2011!
If you have not yet obtained the course text, here are the details:  
The text recommended for this course is Environmental Geology, by C. Montgomery (published by McGraw-Hill).   Note that the bookstore carries the newest, updated edition (though I think that they also have a limited number of older editions?).  If you have access to an older edition of this same text, it will be perfectly useful for this course, and more economical; however, I do suggest that you use a text edition not older than 2 editions previous (i.e., 7th or 8th, instead of 9th). 
Other texts (different authors, publishers) are also available on the subject of Environmental Geology; if you already have one available, please use it, rather than purchasing a new text!  You will, of course, need to select appropriate readings to support the topics we cover.  Note that a text for Environmental Geology will cover different topics--and different aspects of similar topics--compared to a 'Physical Geology' text. 
If needed, I can direct you to additional resources on specific topics.
ONE COMMENT:  Whichever option you choose for a text, it will be to your advantage to have a text resource available as soon as possible




















   This is an especially good course for you if.....

       You plan to be a teacher                    
            or you want to be a journalist             (... if you will be in a position to inform others)

       You hope to be a politician,
           or a business administrator                 (... or in a position to make decisions about environmental
             ... or
if you plan to vote                        issues based on information supplied by others)
You are considering a career in geoscience       (...come see me to sign up as a major!)

Your major is not earth science, but you plan
           to apply your major (any major!) in an environmental career

You simply want to understand better, and not just through the eyes of the media and/or
           special interest groups, about natural hazards, resources, and other important earth issues

You simply are interested in the earth and the environment...
              after all, it is your home!!























  Antarctic Ice Sheet: losses and gains













Modern Battery Chemistry     source:
Modern batteries use a variety of chemicals to power their reactions.
chemical reactions in batteries:


Typical battery chemistries include:

Zinc-carbon battery - Also known as a standard carbon battery, zinc-carbon chemistry is used in all inexpensive AA, C and D dry-cell batteries.
The electrodes are zinc and carbon, with an acidic paste between them that serves as the electrolyte.

Alkaline battery - Alkaline chemistry is used in common Duracell and Energizer batteries, the electrodes are zinc and manganese-oxide, with an alkaline electrolyte.

Lithium-iodide battery - Lithium-iodide chemistry is used in pacemakers and hearing aides because of their long life.

Lead-acid battery - Lead-acid chemistry is used in automobiles, the electrodes are made of lead and lead-oxide with a strong acidic electrolyte (rechargeable).

Nickel-cadmium battery - The electrodes are nickel-hydroxide and cadmium, with potassium-hydroxide as the electrolyte (rechargeable).

Nickel-metal hydride battery - This battery is rapidly replacing nickel-cadmium because it does not suffer from the memory effect that nickel-cadmiums do (rechargeable).

Lithium-ion battery - With a very good power-to-weight ratio, this is often found in high-end laptop computers and cell phones (rechargeable).

Zinc-air battery - This battery is lightweight and rechargeable.

(Zinc-mercury oxide battery - were often used in hearing-aids; now banned in US) ....
silver oxide battery - replacement for mercury batteries

Silver-zinc battery - This is used in aeronautical applications because the power-to-weight ratio is good.
