Supply Companies & Supply List
During the 2006-2007 school year I started teaching a 9-week course on Forensic Science as one of our 8th grade activity classes. A brief outline is available in PDF format - Quarter Outline. Listed below are the powerpoints, worksheets, and other resources I use during the class. I have a SmartBoard in my classroom and many of the presentations (unit and review) are set up so students can help me fill in the answers as we discuss the notes or while they check their worksheets. Please e-mail me if you have any questions.
Attention Illinois Science Teachers ... I will be presenting my Forensic Science unit at the Illinois Science Teachers Association conference. Join me for this session on Friday, November 14th at 9:00 AM in room 210 at the Peoria Convention Center.
Daily CSI Challenges
I created Daily CSI Challenges for this class to target observation and problem solving skills as well as incorporate trivia to review class material or highlight historical cases and people. Students use a Daily CSI bookmarks (PDF) to record their answers and I grade the bookmarks at the end of each week.
All the weekly files listed below right are set up as PowerPoint presentations with challenges for all five days of that week. The first slide for each week includes the names of the days of the week, which are hyperlinks to the slides with the daily challenge for each day. Sources are noted on the individual presentations.

Unit 1: Crime Scene Basics
During this unit students learn basic vocabulary associated with crime scene analysis as well as explore the role of eyewitness accounts and the use FACES software to create facial composites (see the list of supply companies at the bottom of this page.). They also get a chance to investigate a crime through the CHIN Interactive Investigator website, which helps to introduce them to many of the topics we discuss throughout the quarter-long class.

Other activities:
Christmas Cookie Mystery - Use this lesson listed on the Chemistry Lessons page to investigate white powders. The lesson can be adapted to fit any holiday in order to be used at other times of the year.
Tire Tracks (PDF) - This lesson idea was submitted by Sandy Powell, a member of the Middle School Science Yahoo Group. The activity challenges students to match tire tracks of 8-10 small toy cars. Teacher information and a worksheet are provided in the download.
Tire Tracks PPT and Student Worksheet - I use this presentation before completing the tire tracks lab.
Hairs & Fibers (PPT) - I use this presentation to introduce the use of hairs and fibers as evidence. This unit includes an "up close" look at hairs and fibers using microscopes and an assortment of prepared slides. At the end of the lesson, I create four mystery slides using the hair and fiber samples from the labs and challenge students to correctly identify them.
Worksheets:
Hairs & Fibers (PDF) - Student worksheet for the presentation
Hair Lab (PDF) - Includes teacher note
Hair ID Guide (PDF) - Includes teacher notes
Fiber Lab (PDF) - Includes teacher notes
Hair & Fiber Challenge (PDF) - I used my microscope camera to capture images of the various hairs and fibers the students observed in class. I printed several sets of this worksheet on card stock and laminated them to keep them for future classes. I challenge the students to use their notes and observation pages to identify each one.
Chromatography (PPT) - During this lesson students learn about the use of chromatography in crime investigations and use paper chromatography to test black markers. At the end of the unit, I use four of the tested markers to create a Mystery Pen challenge. The students test the four mystery markers and compare them to the samples they previously tested. The challenge is set up as a race to see which student team can be the first to correctly identify them.
Worksheet: Chromatography (PDF)
Other resources: Permanent Marker Chromatography - We used permanent markers and rubbing alcohol to "decorate" our lab aprons.

Unit 3: Fingerprint 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.
Presentation #1: Fingerprint Basics (PPT)
Worksheets: Fingerprint Basics (PDF), My Prints (PDF)
Fingerprint Analysis (PPT) - I use this activity with my students to analyze the distribution of fingerprint patterns in each class. After students complete the My Prints worksheet and classify their prints, they complete the top section of the Fingerprint Analysis worksheet. We calculate the percentages for each pattern and discuss how it relates to the expected percentages presented in class. We also analyze the distrubution of patterns for males vs. females and discuss the results after students have completed the bottom section of the worksheet.

Unit 5: Arson Investigation
Through the help of our local fire department, students explore the basics of fire science and arson investigation. I also include lessons on fire safety and reinforce the fact that playing with fires can cause major damage and deaths. If possible, have a member of your local fire department present a fire safety program for your students. Visit the FEMA website for a good brochure on Children and Fire.

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 a great unit investigating the science behind accidents available through http://www.legalsciences.com/.
NOTE: The CRASH: The Science of Collisions unit 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. It is pricey at $995, but check with your local community groups, police/fire departments, or insurance companies for possible funding assistance. Also check out the Physics of Automobile Crashes book available from the same site for $29.00.
Other resources: It's a Crash Test Dummy (PDF) - A great unit exploring Newton's First Law.
