COURSE NUMBER: CHEM105
COURSE TITLE:Introduction to Forensic Chemistry
DIVISION:Sciences
IAI CODE(S): P1 903L
SEMESTER CREDIT HOURS:4
CONTACT HOURS:75
STUDENT ENGAGEMENT HOURS:180
DELIVERY MODE:In-Person

COURSE DESCRIPTION:
Students will examine the influence of chemistry on society through the study of contemporary issues, with an emphasis on forensic chemistry. Students will be introduced to chemical, biochemical, and microscopy principles associated with analyzing organic and inorganic substances including soil, blood, DNA, hair, drugs, toxins, fibers, and glass. The course meets 3 hours lecture and 2 hours of lab per week.

PREREQUISITES:
Placement into ENGL101 and MATH101.

NOTES: A lab is required for this course. Some sections will require a separate lab, while other sections will include the lab. Not offered every year.
This course is not available for web registration.

STUDENT LEARNING OUTCOMES:
Upon completion of this course, students will be able to:
  • relate current events as well as current and past case studies to forensic chemistry techniques by:
    • Identifying forensic techniques used in criminal cases found in current news articles, news stories, and television shows.
    • Proposing a plan or set of methods to solve criminal cases using forensic chemistry techniques.
    • Judging how current criminal case results set standards for future cases in terms of court rulings, forensic analysis methods and techniques.
  • be introduced to the methods of scientific inquiry and will be expected to do the following:
    • Evaluate questions and situations for solutions.
    • Conduct experiments to explore general chemical and biological analysis techniques of various substances, such as DNA, soils, fibers, hair, etc.
    • Make systematic observations and measurements during classroom discussion and laboratory experiments verbally and in writing.
    • Interpret and analyze data.
    • Draw conclusions from data analyses and results and describe these conclusions through writing.
  • be introduced to analytical chemistry methods and techniques for application to real-life situations:
  • learn approaches used in forensic laboratories for chemical analysis of crime scene evidence.
  • apply chemical analysis techniques to pseudo-evidence.
  • describe and learn the uses of equipment used in forensic chemistry laboratories.

TEXTBOOK / SPECIAL MATERIALS:

Text: Saferstein. 2004. Criminalistics: An Introduction to Forensic Science, 8th Edition, Pearson Prentice Hall.

Lab Manual: Meloan/James. 2004. Lab Manual: Criminalistics, 8th Edition, Pearson Prentice Hall.

Laboratory Notebook: A bound laboratory notebook with duplicate sheets. This is where you’ll record your data in lab. I recommend the spiral bound 100 page carbon copy notebook from Hayden Mcneil Publishers.

Safety Goggles: Students must purchase their own laboratory safety goggles. Goggles are available in the DACC Bookstore. If you already have your own, they must offer complete protection of the side of your eyes. (Look for the markings "Z87" stamped on the goggles.) Lab safety glasses are not acceptable for students.

Calculator: Any simple scientific or graphing calculator is sufficient.

Enclosed Shoes & Pants: For lab days. If you are not dressed appropriately you will not be allowed to participate.

See bookstore website for current book(s) at https://www.dacc.edu/bookstore

EVALUATION:
Grading is based on a weighted percentage of four different categories with overall grade divisions at 90, 80, 70 and 60 percent. The four categories are:
four or more midterm tests
weekly lab current event/case study reports
approximately ten quizzes
a cumulative final exam
40%
30%
10%
20%

Attendance is required and a student may be withdrawn from the class roster due to unexcused absences.

Laboratory work must be performed during the regularly scheduled laboratory period. "Make-up" laboratory work at an alternate time will not be an option. No credit will be given for laboratory reports submitted if the student was absent from that laboratory session. If a student has a valid excuse for missing a lecture or laboratory class, credit for the missed period may be arranged with instructor. It will not be "automatic".

Notes:
All students must pass the laboratory portion of the class in order to pass the course.

The final exam will include all the material that is covered in the semester. Every student is required to take the final exam at the scheduled time. Each student must take and pass the cumulative final exam in order to pass the course.

A curve may be applied at the instructor’s discretion.
