Your first assignment is posted; use the link for the "live syllabus" to see assignments by due date; or jump directly to assignment details
about a  text for this class No specific textbook is required; however, each student must have access to appropriate text references to adequately supplement course topics.  Any earth science or physical geology textbook, published by a scientific or academic publisher in the last 8 years, is appropriate.   

I have recommended a text by Tarbuck, et al., titled Earth Science. Although the current edition is the 13th edition (Prentice Hall, 2011), older editions are perfectly appropriate and widely available at reduced cost on internet sites.  If you have access to a different textbook but are unsure whether it is appropriate for this class, simply come and ask me.

Other resources for reading and reference will be provided in class, posted on the course webpage, or posted in Blackboard. 




   * This outline will be adjusted daily as the semester proceeds.  Please check back frequently for updates.

Course Description
(From the NEIU catalog)
Introduction to Earth Science, 3 cr.  Basic concepts of geology, meteorology, oceanography, and the solar system.  Discussion of topics of current interest in the earth sciences.  Laboratory involves the study of minerals, rocks, maps, and weather instruments. Lecture 2 hours, lab 2 hours. 
Course Prerequisite:
MATH 102 (Intermediate Algebra). 
This course satisfies the General Education Program Natural Science Laboratory requirement.

Course Outcomes:





After successfully completing this course, you should be able to:
Describe the earth as a dynamic planet– the product of various earth processes– and describe the interactions of earth processes in earth systems and cycles.
Describe the structure of the earth and the nature of solid earth materials, and apply the techniques and tools of mineral and rock identification/classification.
Explain the scientific theory of plate tectonics as a framework for interpreting earth form, process, and change over geologic time.
Describe the various physical processes that shape our planet– from within and on the surface– and correlate these processes to geologic phenomena including earthquakes, volcanoes, mountain building, continental movements, weather and climate, and the development of landscapes.
Analyze geologic data from a variety of published sources to interpret Earth processes.
Read  topographic maps, geologic maps, and weather maps well enough to analyze and interpret the data present, and articulate appropriate conclusions.

Emergency Information
It is recognized that a safe university environment is a shared responsibility of faculty, staff, and students, all of whom are expected to familiarize themselves with and cooperate with emergency procedures.

Web links to Campus Safety: Emergency Procedures and Safety Information can be found on NEIUport, on the MyNEIU tab or as follows (for the Main campus):



SECTION 5      Course Requirements           (for more detail, see printed syllabus)
Attendance at all class sessions is expected.  The NEIU policy on class attendance applies to this course.  Frequent in-class assignments will be given and may not be made up.  Students who do not attend regularly will not be given the benefit of the doubt in cases of borderline grades, and a lower grade may be given at the instructor's discretion if absences are excessive. 

The final course grade will be calculated on the following basis:
Scheduled exams (2) 25 %   NOTE:  the rubric for some
assignments (graded by "check" system)
is available in this document
Final exam 20 %  
homework assignments 20 %  
lab activities/ assignments

35 %

Class contribution ("extra credit") +2.5%     

The grading scale is: A 100-90%; B 89-80%; C 79-70%; D 69-60%; F 59% and lower.
All course requirements must be completed to pass the course.  The final date to drop the course, per University policy, is March 30.

Students are expected to check the course webpage and their e-mail at least every other day to watch for course announcements and updates.

Students should bring the following to every class meeting: notebook, handouts, pencil and eraser.  Also bring your textbook if possible.

Students are expected to participate in all course assessments.  On some days, you will be asked to complete anonymous "minute papers", ungraded quiz-type questions, concept maps, or survey-type questions.  This information will help me to determine the extent to which the course is meeting its goals.  To provide me with the most information so that I can make the course better, I ask that you give me your most thoughtful, honest feedback on these assessments.

Academic integrity:  The NEIU policy on academic misconduct will be strictly enforced.   This site from Indiana University explains and gives examples of plagiarism, providing helpful tips on how to avoid plagiarizing.  Cheating on homework, exams, or other course components will result in a score of zero for that element or more severe penalties, as described in the NEIU policy. 

Flexibility: This outline will change as the semester evolves.  Check this page frequently for updates!

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.

1. The first step is that I must add you as a collaborating member of the wiki site.  Do you already have a google account?  (If you use gmail, this is your google account).  If you have a google account, go to step 2.  If not, you must first create a google account: go to  
In the upper right corner, click on "sign in". Below the sign-in box on that page, there is a smaller box that asks, "Don't have a google account?" Click on "Create an account now". This will guide you through setting up an account with your preferred email. In order to complete the process, you will receive a confirming email; follow the directions to finish creating the account.

2. Send me an email from the email account associated with your google account, with the subject: ESCI 121 section (number) wiki.   When I receive the email, you will 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 inviting you to the wiki, it is because you have not yet sent me an email - you should do this immediately!

3. 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 bottom list). If you are on the wiki page and are signed in, but still do not see the "edit page" button, let me know. Once I add you as a user, when signed in to the wiki, you should have full access to the editing functions. 

4. Stay tuned for more directions as to how we will use the wiki!
