General Education Requirements

Chem 105 fulfills three hours of general education requirement for natural sciences. The writing requirements will be fulfilled through quizzes, exams, and the final cumulative exams. Students will be required to demonstrate an organized and logical approach to problem solutions. The solutions must show and understanding of the fundamental concepts, and use mathematical operations, unit conversions, and proper significant figures in order to determine the proper answers.
Listed below are the seven fundamental student learning outcomes for natural science courses as well as examples of how they will be fulfilled in Chem 105.

Students should be:

1. Conversant with a few fundamental concepts from among the three main areas of natural science, including earth, life, and physical sciences. (e.g., chemical reactions, conservation of mass,...)

2. Able to apply the scientific methodologies of inquiry. (e.g., Problem solving exercises)

3. Able to discuss the strengths and limitations of science. (e.g., discussion of scientific methodology)

4. Able to demonstrate an understanding of the history of scientific discovery. (e.g., The development of the periodic table and discovery of subatomic particles)

5. Able to discuss the social and ethical contexts within which science operates. (e.g., application of the scientific method).

6. Able to communicate about scientific subjects including the defense of conclusions based on one’s own observations. (e.g., homework assignments and analytic exam questions)

7. Able to discuss the application of scientific knowledge to the social sciences and to non-scientific disciplines. (integrated throughout the course)

 Course Outline:

In this course, we will examine the following topics:

●   Unit Systems and Dimensional Analysis

●    Chemical Equations: Net Ionic and oxidation-Reduction
●    Reaction Equilibrium
●    Reaction Kinetics

Class Preparation: In order to succeed in this course you must keep up with the assignments and manage your time wisely. Therefore, you should:

Watch the video lectures which are linked in the online assignments prior to attempting each assignment, and complete Blackboard assignments on time. 

Check Blackboard daily for important announcements, and pay close attention to the instructions for assessments (quizzes and exams), as well as due dates. 

You are responsible for any announcements made via Blackboard, or by email. Ensure that Blackboard is set to send announcements to your email address, and check your email daily.

Devote time to study each day.  This is a rigorous course that requires daily preparation.  Work homework/practice problems daily.

Take good notes and develop good study habits. Many students with good work ethics often still need to change how they approach studying for this course. Working problems independently is necessary to improve your comprehension and problem solving skills. Supplemental work with tutors or fellow students can also be advantageous. 

Work out all problems on paper, whether for exams, quizzes, or practice, and make sure to keep track of units and significant figures. This develops better problem solving skills, aids you in catching careless mistakes, and helps me or your tutors in troubleshooting your work. In addition, parts of some quizzes and exams will require you to show your work in order to receive credit.

Use your time wisely. Online quizzes typically have at least a three day window to complete and have multiple attempts (with different questions every time). Start your attempts early rather than waiting until the deadline. Review previous attempts so that you may learn from your mistakes before taking the quiz again. This also gives you time to ask me for assistance between attempts.

Exams and Grading:


Exams and Quizzes: You will need a scientific calculator (one with exponential notation, logarithms, and orders of operation) for exams and quizzes. 
Use of cell phones and sharing of calculators are both strictly prohibited during exams and quizzes. You will also need a computer with internet access and a web camera for exams (and for a ‘quiz’ to test your equipment).

Course Withdraw: March 11 is the last day to withdraw from a full semester course with an automatic N grade issued.  Students may not withdraw from a course after this date without documented extenuating circumstances as determined by the University.

Communication: You are required to use your Winthrop University email address when communicating with classmates or me through email. All communications about this course will be sent by me to your Winthrop email address and you are required to use your Winthrop email address when sending emails to me. When sending me an email, please use “CHEM 104” in the subject line. If you use another email account, it is possible that your email will go to my junk folder. I will reply as promptly as possible, depending on my availability. If you do not hear from me within 24 hours on weekdays, or 48 hours on weekends, please send me a reminder in case your email did not get through.
The first quiz will be posted on the first day of class, Monday, Jan 11. You should receive an alert from Blackboard and a separate email from me. If you do not get my email by Tuesday morning, send me an email ASAP so the we can address this issue and insure that you receive all communications. If you do not get the alert from Blackboard, go into Blackboard and adjust the notification settings.

Attendance:  You are expected to actively participate in the course, and keep up with all announcements made in Blackboard or sent via email. Participation includes replying to emails requesting a response, completing online assignments, and contacting the instructor with any questions or concerns. Absences include not responding to instructor requests and failure to complete online assignments.

Online learning: Any student enrolled in courses at Winthrop regardless of modality (traditional in-person, online, hybrid, ...) is entitled access to all campus resources. These resources include, but are not limited to, admissions counseling, recreational facilities, and health, library, and academic services. Questions regarding access to these resources should be directed to the assigned academic advisor.

Masking Expectations: Winthrop requires that all students adhere to safety practices that will minimize the transmission of COVID-19 within the campus community. Accordingly, students are expected to engage in social distancing and wear a cloth face mask while on campus. Failure to comply with this requirement in the classroom will result in dismissal from the current class meeting. Repeated violations will be reported to the Dean of Students as a violation of the Student Conduct Code. Students with conditions that prohibit the wearing of a face mask should discuss this with their instructor and/or contact the Office of Accessibility to arrange appropriate accommodations.

Students with Disabilities/Need of Accommodations for Access:

Winthrop University is committed to providing access to education.  If you have a condition which may adversely impact your ability to access academics and/or campus life, and you require specific accommodations to complete this course, contact the Office of Accessibility (OA) at 803-323-3290, or,,as early as possible to discuss your concerns.

Academic Success Center: Winthrop’s Academic Success Center is a free resource for all undergraduate students seeking to perform their best academically. The ASC offers a variety of personalized and structured resources that help students achieve academic excellence, such as virtual tutoring and academic coaching. The ASC is located on the first floor of Dinkins, Suite 106.  Please contact the ASC at 803-323-3929 or For more information on ASC services, please visit

To utilize ASC Peer Tutoring during the 2020-2021 semester, students must enroll in and complete the Tutee Seminar on Blackboard. A two minute video on how to enroll so can be found on the bottom of the webpage. Upon completing the Tutee Seminar, students can register for up to two ASC Peer Tutors each semester via Tutor Trac ( ). Students who experience any difficulty with the registration process can contact the ASC at 803-323-3929 or


***This document may be adjusted as needed during the semester. The student is responsible for being aware of any changes and so should check the department website,, prior to every class for changes to this syllabus.

This is a tentative schedule and will be revised as needed.
