Design Criteria for a Property & Evidence Room
By Vickie Brugger
In this animated, audio and graphic activity illustration, learners will view design criteria for properly storing property and evidence.
Learners will be able to identify areas within the property room including adjoining work areas, work flow, temporary storage, long-term storage, high profile items, bulk or oversize items, biohazards, hazardous materials, cold storage, administrative area, and release areas.
Directionality of Broken Glass
By Ronald Groffy
Visualizes direction and amount of glass particles travel when impacted by a force.

Heavy Truck Electronic Control Modules
By Timothy Austin
This learning object is designed to show students they types of information that can be imaged from the Electronic Control Module employed by heavy truck engines.
Documentation of Bloodstain Evidence (Screencast)
Students will learn how to document bloodstains using roadmapping equipment materials
Passenger Vehicle ACMs and PCMs
Video based Learning Object showing passenger vehicle and light duty truck Event Data Recorders (Airbag Control modules and Powertrain Control Modules).
Seatbelt Evidence
This Learning Object is designed to identify the various components of a vehicle's seatbelt system, and to show evidence of seatbelt use following a collision.
Summary of Bloodstain Evidence Documentation (Screencast)
This activity will summarize the bloodstain evidence documentation process.
Directionality and Amount of Broken Glass (Screencast)
Visualizes direction and quantity of glass particles as the glass is impacted by a force.
Angles of Impact (Screencast)
This screencast, we see how the shape of a stain defines the angle of impact. In general terms the more circular the stain, the more perpendicular will be the angle at which it struck the surface. The more elliptical the shape of the stain, the more acute the angle will be. With practice and experience, the analyst can recognize the general angle of impact based solely on the shape of the stain.
Chain of Custody
This video illustrates what can happen in a court room when chain-of-custody procedures for collecting evidence are either ignored or not carried out properly.
Surface Tension of a Blood Drop (Screencast)
This screencast shows how blood droplets are held together by a strong cohesive molecular force that produces surface tension in each drop and on the external force. Surface tension pulls the surface molecules of a liquid toward its interior, decreasing the surface area and causing the liquid to resist penetration.
Distance Fallen vs. Stain Diameter (Screencast)
Learners observe how a blood drop in flight continually accelerates and increases in velocity over time. As the drop falls, resistance accumulates. The increase in stain diameter relative to distance of a typical 50 ml drop of blood is represented here. This activity has audio content.
Spatter Drop Dynamics on Impact (Screencast)
In this screencast, the student will learn that regardless of the surface onto which a blood droplet is falling, the angle or velocity at which it does so, or the volume of the droplet, there are four distinct phases involved in the reaction of a moving droplet with impact against a surface.
Forensic Lamp Examination (Screencast)
This learning object is designed to assist students in understanding and interpreting collision evidence found in automotive lamps. In particular, the concepts of Hot Shock, Cold Shock, Hot Break, and Cold Break will be visually addressed.
Materials for Bloodstain Pattern Mapping, Preservation & Documentation (Screencast)
This learning object describes the equipment and supplies needed to document bloodstain patterns.
DNA Collection Methods Corrections
By Dan Mader
This learning object will be used in conjunction with the DNA collection methods learning object. This learning object will cover the errors that were present in the DNA collection methods learning object and how they could be corrected.
Aspergillus in the Property Room
In this learning activity learners will be hear about aspergillus found on marijuana and the potential health hazards that can affect a property room manager. Learners will hear about preventative measures.
Collection of Entomological Evidence Test
By Amanda Thoma
A crime scene photo for determination of time since death. The student will need to collect the evidence into the correct item.
Using an Evidence Bag
By Joe LeFevre
Explore how to use an evidence bag including how to open it, place items inside, and seal it for the crime lab.
Sequencing Impacts Using Radial and Concentric Fractures (Screencast)
Learners examine radial and concentric fractures in glass to determine the sequence of the impacts.
Collection of Entomological Evidence
Learners view the scene of a suspicious death and select the evidence that needs to be collected.
