Forensics is the interdisciplinary application of science to investigate and analyze evidence of historical, and most often criminal, events. In the classroom, training forensic scientists requires preparing students to be able to identify, compare, and analyze a breadth of evidence types using skills across biology, chemistry, and physics.
This guide provides information, products, free digital resources, and suggestions for teaching the most common types of evidence in forensic science. The types of evidence covered in this topic are:
- Fingerprinting
- Blood Evidence
- DNA Evidence
- Forensic Anthropology
- Trace Evidence
- Ballistics and Toolmarks
Fingerprinting
Fingerprints are the impressions made on a surface from contact with a person’s fingertips. Because the patterns and ridges of human fingerprints are different between individuals, forensic investigators can use fingerprint evidence to make individual identifications. In the field, a variety of tools such as inks, powders, and chemicals are used to obtain and visualize prints. Below are just a few of the authentic forensics supplies Carolina offers for your fingerprint evidence investigations.
Make your next classroom activity truly unique by having your students uncover their fingerprint patterns. A great introductory lesson for students of all backgrounds, this kit teaches about basic fingerprint patterns, minutiae, and the Henry system of classification.
Beginning–Easy to perform; requires little or no prior knowledge.
Give your students a real-life forensics experience as they discover the science of fingerprint development with powders. Students will develop fingerprints with magnetic powders and alternate light sources.
Intermediate–Easy to perform; requires some background knowledge.
Give your students the opportunity to become crime scene technicians as they discover the science of latent fingerprint development. Students will develop fingerprints using ninhydrin and DFO in this activity.
Advanced–For experienced high school and college classes; requires some technical skill and background knowledge.
Blood Evidence
Blood evidence is a diverse and multifaceted domain of forensics that provides opportunities for teaching a variety of subjects and techniques from chemistry, biology, and physics. Simulated Kastle-Meyer tests can be used to determine if an unknown sample is blood or a blood-like substance. Blood typing examines cell structures and immune functions to obtain useful class evidence on the blood type (A, B, AB, or O) of a sample. And the patterns of blood spatters found at a crime scene can be used to estimate the angle, velocity, and point of origin for a spatter. Whichever subject you use blood evidence for, we have you covered!
Students perform a simulated test for the presence of blood on evidence collected from 2 suspects in a murder case. They then use synthetic blood typing to test whether either suspect can be linked to the crime.
Intermediate–Easy to perform; requires some background knowledge.
Give your students the opportunity to become crime scene technicians as they analyze bloodstain patterns. Students will use trigonometry to determine angle of incidence and point of origin for a blood pattern.
Advanced–For experienced high school and college classes; requires some technical skill and background knowledge.
Forensic Anthropology
When human remains are discovered at a crime scene, how do forensic investigators determine who died? How old they were? How tall? What biological sex? Forensic anthropology is the application of anatomy, physiology, and anthropology to determine the answer to these questions to aid in solving criminal cases. We offer detailed, replicated skeletal remains and activities for your students to engage with forensic anthropology in your classroom.

Students use basic science process skills to solve a mystery in this investigation-based introduction to skeletal anatomy and forensic anthropology. Students act as forensic scientists as they examine and identify a variety of bones, predict their origins, and make inferences based on observations and evidence collected at the crime scene.
Beginning–Easy to perform; requires little or no prior knowledge.
How much can you learn about individuals by simply examining their bones? That’s what students find out as they become forensic detectives in a local missing person case. This forensics education kit comes with a set of 3 plastic bones (skull [with 3 removable teeth], arm bone, and leg bone) that were recently unearthed from a field near the school. After examining and identifying the bones, students use skeletal characteristics to determine as much information as possible about the person, including race, gender, and height.
Intermediate–Easy to perform; requires some background knowledge.

Cast from an original skull that is in a North American medical school forensic osteology teaching collection. The appearance of the projectile damage to bone is crucial in differentiating entrance and exit wounds.
Typically, as a projectile (such as a bullet) passes through a plate of bone, fragments of the bone follow. The result is a characteristic beveling (or open fanning) of the bone in the direction of projectile motion.
Advanced–For experienced high school and college classes; requires some technical skill and background knowledge.
DNA Evidence
DNA is the gold standard of individual evidence because no two human genomes, except for those of identical twins, are identical. A common practice of DNA analysis for forensic investigations is to create and compare DNA fingerprinting profiles, which examine small regions of repetitive DNA that vary between individuals. Making DNA fingerprints often requires the use of gel electrophoresis, PCR, and other biotechnology techniques. We understand that knowledge of, and access to, biotechnology can vary from classroom to classroom, so our kits are designed to meet your unique needs, whether you’re a first-time teacher or a seasoned expert.
In this lab students learn about DNA analysis methods by performing gel electrophoresis to create simulated DNA fingerprints for use as evidence to solve a forensic case.
Students are presented with the crime scene, the suspects, the PCR process used to prepare the evidence, and are then asked to set up, run, and analyze an electrophoresis gel to determine whether one of the suspects is connected to the crime. The question that drives their investigation is, “How do we use DNA evidence, and what must be done in order to use it?”
Beginning–Easy to perform; requires little or no prior knowledge.
This advanced lab uses plasmid isolation and restriction analysis to illustrate forensic DNA typing. Students are provided with 2 samples of E. coli cells to represent blood samples from 2 suspects. Plasmid DNA is extracted using a miniprep procedure and cut with restriction enzymes, along with a DNA sample representing the evidence from a crime scene.
Advanced–For experienced high school and college classes; requires some technical skill and background knowledge.
This kit takes your forensics class to the next level by giving students the opportunity to analyze DNA samples from a (fictitious) crime scene. Students immerse themselves in attempting to identify the culprit, learning more about DNA profiling and the role of tandem repeats in the analysis. They build on that knowledge with a hands-on investigation of the samples using PCR amplification and gel electrophoresis to help close the case.
Advanced–For experienced high school and college classes; requires some technical skill and background knowledge.
Trace Evidence
Every contact between a suspect and a surface will result in a transfer of minute substances that can provide helpful trace evidence to investigators. Trace evidence can be either biological or physical, and each category of trace evidence has unique characteristics and investigatory techniques. From fibers to hair to glass, our kits can help your students become experts at analyzing trace evidence.
Introduce forensic fiber identification techniques by challenging your students to identify an unknown fiber with this fiber identification kit. Students perform fiber diagnostic tests–such as burn tests, stain tests, microscope analysis, and more–to both reference fibers and an unknown fiber. Using the test results as evidence, students can conclusively identify the unknown fiber.
Intermediate–Easy to perform; requires some background knowledge.
In this lab, students learn how to identify hair characteristics, including cuticle, cortex, medulla, and shape of the hair shaft. They also learn how to use a microscope and their unaided eyes to identify these characteristics. This activity includes all the tools teachers and students need to conduct the lab (except for microscope). Based on details from the Diablo Highway Kit (item #212188) crime scene, this lab can also be used as a stand-alone activity.
Intermediate–Easy to perform; requires some background knowledge.
Every piece of evidence provides a clue about a crime. This kit shows the physical and chemical characteristics of different types of glass to illustrate how forensic scientists assemble evidence to solve crimes.
Intermediate–Easy to perform; requires some background knowledge.
Ballistics and Toolmarks
If a crime involves a firearm, tool, or a scuffle, impressions will likely be left behind that, when analyzed, yield insights into what has occurred. Projectiles from firearms will leave impact that can be used to determine the trajectory and point of origin from their use. Tools such as pliers and screwdrivers, when struck on a surface, produce impressions that can be identified and traced to a unique tool. Shoe prints vary between shoe manufactories, making footwear prints a good source of class evidence. Below are just a few examples of kits that are sure to make an impression with your students.
Toolmark identification determines if a particular tool produced a mark when tools are used to commit a crime. 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.
Intermediate–Easy to perform; requires some background knowledge.

Utilizing the same materials and tools as crime scene technicians worldwide, your students get an authentic first-hand experience with this activity. First, students make prints of their own shoes, using a special no-mess inkless shoe-print technology, to learn about pattern recognition. You then demonstrate the process of creating, cleaning, and handling a footwear cast using a no-mess, self-contained casting product designed specifically for crime scene field technicians.
Intermediate–Easy to perform; requires some background knowledge.
