FORENSIC IMPRESSION KIT
When an investigator enters a crime scene, it is extremely important not to destroy any form of trace evidence that might lead
to the apprehension of the criminal in question. A close examination of a crime scene will often reveal impression evidence that
has been left there by the perpetrator of the crime. It is simply impossible to enter a location without changing it in some way,
either by bringing something to it or by taking something from it. Footprints or shoe prints, tire tracks, or other impressions imbedded
in soft material, if properly identified, preserved, and evaluated, may allow the crime scene investigator valuable class
evidence. This type of evidence may not convict the doer of the wrong deed, but may lead to their apprehension. Your students
actually get to become CSI detectives and perform many of the same duties, and solve the scenario in this kit, by using 6 different
labs included. For 6 groups of 4 students.

FABRIC AND FIBER KIT
Students perform four experiments analyzing fabric and fiber samples to learn to characterize types of fabric and fiber, then
do an unknowns lab. First students determine if each sample is animal, vegetable, mineral, or synthetic in origin by subjecting
fibers to a burn test and evaluating fibers for protein and for the presence of sulfur. Then, students observe fiber samples to
identify their general microscopic characteristics, subject fiber samples to chemical solubility tests, and subject fiber samples
to stress and strain tests. Following their training and exposure to background information including techniques for proper collection
of fiber evidence, students test three unknowns to determine their identity. Includes instructional manuals and student
worksheets. Designed for 24 students working in six groups of four students each. Meets national standards for grade levels 10-
12. Designed for grade 10-14.
