Grade 9–College. A large amount of trace evidence is collected during the investigation of the cabin. Recent additional trace evidence—gathered from the Tumbling Water Land Development Co. truck discovered in New Mexico—arrives. Students are tasked with analyzing hair and fiber evidence. Using the kit, students learn about evidence handling and comparison.

The manufacturing process of tool-making leaves patterns embedded in each tool's surface. These unique patterns become evidence when criminals use tools to commit a crime. Toolmark identification determines if a particular tool produced a mark.

The Complete Kit has everything your students need to become expert analysts of tools and the marks made by them. With 4 lab exercises based on actual cases encountered in crime laboratories and a detailed PowerPoint® lecture on the manufacturing of tools, students can experience the same type of training given to forensic scientists. Kit also includes enough materials for 30 students and a test bank of questions based on the lecture.

To enhance your lesson, purchase the Toolmark Poster (item #212161), which illustrates different tools and their respective marks.

Hairs and fibers are removed from trace-evidence collection tape by dissolving tape adhesive in water, then filtering hairs and fibers from the resulting solution. Next, students characterize the hairs and fibers using microscopy. After processing all the evidence, students attempt to match hair and fiber types from the truck to those found in the cabin. The kit includes supplies for up to 30 students working in 6 groups and is matched to National Science Education Standards. Fully illustrated teacher's manual provides technique background. Note: Kit can be shipped and stored at room temperature.

Rated 1 out of 5 by from Adhesive The kit might be good to use if we could actually dissolve the adhesive and obtain our samples. My students struggled to get the hair and fibers off the adhesive tape from the cabin. It was hard for me to evaluate the rest of the features of this particular kit because we couldn't get past the first step during the lab. Clearly the evidence needs to be more easily obtained - either by suggesting that we use an different solvent (acetone or alcohol perhaps) or by suggesting that the adhesive be dissolved overnight or over a long period of time ahead of the lab
