Introduction

You should have completed FRNSC 100 (Introduction to Forensic Science), CHEM 110, and CHEM 111 which are the prerequisite courses for FRNSC 210. You should also be familiar with Penn State’s online course delivery system. This course is offered online only and accessible via CANVAS. Successful completion of FRNSC 210 is required before entrance into the remaining Forensic Science major courses. This course is designed to prepare students for entry into the undergraduate forensic science program by providing theory and knowledge essential to success in the 400 level forensic science courses and in the profession of criminalistics/forensic science. The associated skills and abilities will be further developed in later courses of the forensic science program. In this course, students will learn essential principles of criminalistics. The necessity of an objective, rigorous scientific approach in forensic investigation will be stressed.

Overview

The course is broken into two major sections:

  • Part 01 - Ethics, accreditation/certification, observation, documentation, and communication
  • Part 02 - Light, optics, microscopy, and photography. These topics will be utilized in your professional career as well as further explored during your forensic science curriculum at Penn State.

Policies

Academic Integrity

All Penn State policies regarding ethics and honorable behavior apply to this course and each student must abide by the Academic Integrity policies set forth by the University Faculty Senate (Policy 49-‐20: Academic Integrity) and the Eberly College of Science. Academic dishonesty is not limited to simply cheating on an exam or assignment. The following is quoted directly from the “PSU Faculty Senate Policies for Students” regarding academic integrity and academic dishonesty: “Academic integrity is the pursuit of scholarly activity free from fraud and deception and is an educational objective of this institution. Academic dishonesty includes, but is not limited to, cheating, plagiarizing, fabricating of information or citations, facilitating acts of academic dishonesty by others, having unauthorized possession of examinations, submitting work of another person or work previously used without informing the instructor, or tampering with the academic work of other students.” All University and Eberly College of Science policies regarding academic integrity/academic dishonesty apply to this course and the students enrolled in this course. It is your responsibility to be thoroughly familiar with all policies and sanctions. They can be accessed at:

While discussion of course concepts and cooperative study are strongly encouraged, any collaboration, discussion, assistance, cheating (use of friends, books, notes, the internet, etc.) and plagiarism, etc., are NOT permitted during quizzes, examinations or any other assignments unless otherwise specified in writing by the instructor. All exam answers must be your own, and you must not provide any assistance to other students during quizzes homework, or exams. Any collaboration, discussion, assistance, cheating (use of friends, books, notes, the internet, etc.) about or during a quiz, examination, exercise, homework, assignment, or commit plagiarism or other unethical or dishonest behavior, will result in failure of the quiz, examination, exercise, homework, and/or assignment and may lead to failure of the course and University disciplinary action. Integrity violations become part of your record. Integrity and ethics are considered exceptionally important by the instructor and course assistants. You are entering a profession where your integrity is of paramount importance and cannot be suspect in any way. Do not think lying, stealing, or cheating will be tolerated. Do not tolerate this in other students in the forensic science program – report it. The sanctions will depend on the offense severity. No credit on the quiz, exam, exercise, homework, assignment, or other class assignment and may range to include failure of the course. Ethics violations become part of the academic record.

Each student in this course is expected to work entirely on her/his own while taking any quiz or exam, to complete exercises or other assignments on her/his own effort without the assistance of others unless directed otherwise by the instructor, and to abide by University and Eberly College of Science policies about academic integrity and academic dishonesty. Academic sanctions are determined and assigned by the instructor or by the instructor together with the College Academic Integrity Committee. Disciplinary sanctions may be recommended by the instructor, the College Committee, or the Associate Dean, and are assigned by the Office of Judicial Affairs. The XF grade is a disciplinary sanction that is only assigned with the concurrence of the instructor, the College of Academic Integrity Committee, and Judicial Affairs.

Code of Mutual Respect

The Eberly College of Science Code of Mutual Respect and Cooperation embodies the values that we hope our faculty, staff, and students possess and will endorse to make The Eberly College of Science a place where every individual feels respected and valued, as well as challenged and rewarded.

Late Work Policy

Because the student has at least seven (7) days to complete homework, quizzes, and exercises, late submissions will not be accepted for full credit without PRIOR authorization from the Instructor. Extensions may be granted for exigent circumstances if the instructor is informed ahead of time (documentation may be requested) and believes the extension is warranted. Not all circumstances may be considered exigent or worthy of delay by the instructor. Contact the instructor or your course assistant as soon as possible with any issues or concerns or if you have questions.

If no authorization has been granted, late assignments (homework and exercises - NOT quizzes and exams) will have 10% (2 points) taken from the final grade of the assignment for every 24 hours that passes from the due date. For example:

  • If the assignment is due at 11:59pm on Wednesday night and you submit it at noon on Thursday, you will have 10% (2 points) taken off your final grade for the late assignment. If you earn 17/20 for that assignment, your grade will be lowered to 15/20.
  • If the assignment is due at 11:59pm on Wednesday night and you submit it at 12:00am on Friday morning, you will have 20% (4 points) taken off your final grade for that late assignment. If you earn a 17/20 for that assignment, your grade will be lowered to 13/20.
  • For an exercise worth 50 points, it is 5 points off per 24 hours late, 10 points off for 100 points exercises, and 20 points off for 200 point exercises.

Improperly submitted homework and exercises will be considered late until they are resubmitted properly. Your CA cannot grade what they cannot read. Email your CA to check for proper submission of your homework if you are concerned – give them at least 24 hours to respond. Some examples of improperly submitted work include:

  • Blank or incomplete work on the assignment
  • The wrong document was submitted
  • Photos, copies, or scans of the document are too faint or illegible
  • The assignment was emailed to a CA instead of uploaded to Canvas
  • The work was cut and paste into a text box instead of submitted
  • The document submitted is not a Word document or is in an un-openable or corrupted format

If no authorization has been granted, quizzes and exams cannot be made up. You will receive a grade of zero for missing quizzes and exams if you have not received prior approval from the instructor before the quiz or exam window closes.

Reference Cards
I have created reference cards for many of the units/activities listed below, which are designed to replace the student worksheets and some lab pages for those units. The cards are printed on card stock (back-to-back) and laminated for student use. Students use overhead markers to add notes to the pages as we discuss each lesson and keep them to review for the unit quizzes. (You could also have students record their answers in a lab notebook rather than write on the pages.) At the end of the unit, they clean them off with a wet cloth and turn them in so they are ready for the next class! Less paper wasted and less time copying - a double bonus! In addition, the reference card format will allow special education students (and other students with learning challenges) to focus on the lesson and avoids possible frustration at trying to keep up with the class notes. They will have all the information they need in one place.

Daily CSI Challenges

I start each class period with a warm-up activity targeting forensic science concepts and other skills (observation, problem-solving, etc.) The challenges are in the form of PowerPoint presentations and include spot-the-differences puzzles, mini mysteries, trivia challenges, and vocabulary builders. I have also created several warm-ups that incorporate CSI-related videos that are available online.

Fingerprinting Basics

During this unit students learn how to identify the different fingerprint patterns as well as other details that help investigators match fingerprints. They are able to practice making and lifting prints and are challenged to match unknown and known in the Fingerprint Challenge. I purchased ink pads, black powder, brushes, and other materials to make several kits to allow students to work in small groups. See the list of supply companies at the bottom of this page.

NOTE:  I highly recommend the magnetic fingerprint wands and dust if you have the money available to purchase them. They are less messy than the traditional black powder and fiber brushes.

We calculate the percentages for each pattern and discuss how it relates to the expected percentages presented in class. We also analyze the distribution of patterns for males vs. females and discuss the results after students have completed the bottom section of the worksheet.

My Toe Prints worksheet (PDF) - Students are always interested in examining their toe prints to see how they compare to their fingerprints. Instead of using the incapax from the fingerprint unit, the students create their own "ink" by rubbing pencils on an index card and then pressing it to their toes. They use a piece of clear tape to lift the print and tape it to the correct spot on the worksheet.

Lip Print Activity (PDF) - Thanks to Dina Sbarra for sharing her lip print mystery activity. Shewent around the school and got lip marks from several teachers at her school on paper and then put them in sheet protectors. She  had one teacher also mark their lips on a plastic cup (the criminal that destroyed her room). She toilet papered my room and the students had to find out who did it. She put the lip prints on the screen so they could look at the various types to help them classify the lip prints and identify the one from the culprit.

Unit 6: Accident Reconstruction

During this unit students investigate Newton's Laws of Motion to analyze an accident scene to determine the sequence of events that lead up to the accident, explain damage resulting from the accident, and "solve" cases. I use activities from CRASH: The Science of Collisions, which is geared towards the high school level, but several of the activities targeting Newton's Laws can be used at the junior high level. Our district purchased the CRASH kit and I share it with the high school physics teacher. Many of the lessons could also be incorporated into driver's education classes. Use the contact form on their website to see if your high school can receive the program for free!

CSI Adventure

I developed this geocaching activity for use with the CSI summer camp program at the Smithsonian in DC. For this activity, teams of students use GSP receivers to find 10 "evidence" caches. Each cache contains a cache card with 3-4 questions the students must answer or tasks they need complete. Each cache has a different theme and relate to the material the students investigated during the camp. After a team completes a cache and has all the correct answers, they are provided with a clue card that will help them determine the next waypoint in the adventure.
