Course Description

Includes the basic sciences which describe our physical environment. Includes the fundamentals of geology, meteorology, physics, chemistry, and biology. Describes basic scientific principles and relates them to natural phenomena and the activities of man. Emphasizes field experiences, including techniques and data gathering. Lecture 3 hours. Laboratory 3 hours. Total 6 hours per week.


Goals/Specific Objectives

SCT 112 is the second in a two-semester series, designed to introduce students to basic sciences, which describe their physical environment. As in any introductory science course, the student will be introduced to the nomenclature of science so that he/she may continue in more advanced classes.

  1. Those topics on the course syllabus are the specific objectives of the course.
  2. The intent of this course will be to provide the student with a foundation by which he/she may pursue more in-depth courses in the field of environmental science.



Instructional Methods

Late lab exercises will be accepted by will be reduced one point for each week past due. Cheating or copying another student's work will not be tolerated. A grade of zero (0) will be given if you are caught cheating.

For Your Information:

All correspondence and assignments should be sent to the email address listed above.

Since SCT112 is an online course, each student is expected to check his or her Mountain Empire email address at least twice weekly. If you are having problems using your Mountain Empire email address, please contact the instructor as soon as possible.

The instructor will use email to keep you updated on your progress throughout the course. If you have completed any kind of assignment and have not heard from the instructor within a reasonable length of time (two work days if the assignment was turned in over the internet or a week if the assignment was turned in through the postal service), then you should contact the instructor to make sure that your assignment was received.



Emergency Statement

In the event of a College-wide emergency, course requirements, classes, deadlines, and grading schemes are subject to changes that may include alternative delivery methods; alternative methods of interaction with the instructor, class materials, and/or classmates; a revised attendance policy; and a revised semester calendar and/or grading scheme.

In the case of a College emergency, please refer to the following about changes in this course:


·         If you are unable to access the water/wastewater distance learning website, please contact IT services at 276-523-2400 or contact your instructor.  If power or servers are down across campus it may take a couple of hours for service to be reinstated.  Please be patient and your course material will be back up and running shortly.  If this does occur penalties will not be given for late assignments.

·         If the MECC mail server is down your instructor will use the following email address: Caogbonnaya1975@yahoo.com.
*****Please note that this email address will ONLY be used in case of an emergency when the MECC mail server is down!******

·         The telephone number for your instructor is as follows:
276-523-2400, ext 276

For more general information about the emergency situation, please refer to:

·         The Mountain Empire Community College web site at www.mecc.edu or the Virginia Community College System web page at www.vccs.edu

·         The college phone number is 276-523-2400

·         The college phone number to call in case of snow or inclement weather is 276-523-7495. You may also receive information about snow or inclement weather at the following TV and Radio Stations:

·         You may contact security at MECC from off campus by calling 276-523-7473 and from on campus by dialing 473 from any campus phone. There are also several emergency security phones located on MECC’s campus.



Emergency Notifications: When MECC considers an emergency to pose an ongoing threat to students and employees, the college community will be notified in several ways:

1.    Text Message (register to receive text messages from MECC at http://www2.mecc.edu/sms/index.html)

2.    Email

3.    Telephone

4.    Postings on the college’s web site

5.    In person




All students at MECC should abide by the standards of conduct outlined in the MECC Student Handbook. Cheating WILL NOT be tolerated. Anyone caught cheating on an assignment or test will receive a zero for that assignment.



Attendance Policy

Regular class attendance is required. When absence from a clas is necessary, it is teh responsibility of teh student to inform the instructor prior to the absence. The student is responsible for teh subsequent completion of all work missed during an absence. (MECC Student Handbook).

Mountain Empire Community College is committed to academic quality and student success. Elements that support both of these values are regular attendance and participation in class. The college policy states that regular class attendance is required. The attendanc epolicy in this class is that you spend at least 5 hours per week working on assignments, which will help ensure you stay on track.




Instructions for Individuals with Disabilities

Students may request academic accommodation for disabilities through the Office of Student Services.  That office will evaluate the request and make recommendations for appropriate and reasonable accommodations, which the student will provide to the instructor.

Individuals requiring temporary handicapped parking accommodations due to short-term illness should also contact Student Services.

All correspondence will be kept confidential.

Laboratory Projects for SCT 112

You can choose any scientific topic that we have covered in class (SCT 111-112). I must approve this topic before you start working on it. It can be any lab experiment that we have carried out in class, but you should be able to expand it to cover the rest of the semester.

A 2-3 page "proposal" (type written) will be required before you start on your topic of interest. Your final report will be a 7-10 page typewritten scientific report.

  1. Proposal - 10 points
  2. Presentations - 20 points (This will be done over the phone.)
  3. Grading of paper - 70 points
  4. Total - 100 points
