The Duties of the Three Branches of Government (Screencast)
In this screencast, explore the legislative, executive, and judiciary branches of the U.S. government. External resource: www.usconstitution.com
Formation of Radial and Concentric Fractures in Glass (Screencast)
By Ronald Groffy
in this screencast, learners examine the formation of radial and concentric fractures as an object breaks a pane of glass.
Entering a Room: A Video Demonstration
By Kelly Kent
Learners watch video clips demonstrating the correct procedures for police officers to follow when entering and clearing a room.
Dusting for Fingerprints
By Joe LeFevre
Discover how to select the correct fingerprint powder, the proper dusting and collecting techniques, and how to fill out an evidence card.
Stain Measurement & Calculating Angles of Impact (Screencast)
By Daniel Feucht
In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).
A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.
Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
Human Skeleton Test
By Amanda Thoma
A human skeleton test will be taken by students. They will need to label all bones of the skeleton.
Careers in Criminal Justice
By Christopher Farrell
Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.
Police Officer Hiring: An Overview of the Selection Process
By Megan Desmond
Learners read about the steps involved in the typical police officer hiring process. Each step is described. Learners then test their knowledge of the process in two drag-and-drop exercises.
High-Risk Contacts: A Video Demonstration
Learners watch a short video showing the correct procedure for police officers to follow when making contact with a high-risk vehicle.
Approach Contacts: A Video Demonstration
Learners watch a short video demonstrating the correct procedure for police officers to follow when approaching a motorist after stopping a vehicle.
Non-Approach Contacts: A Video Demonstration
Learners watch a short video showing the correct procedure for police officers to follow when making a non-approach vehicle contact.
Metering a Room: A Video Demonstration
Learners watch video clips demonstrating the correct procedure for police officers to follow when metering a room.
Human Skeleton Quiz
I would like to have a human skeleton where specific bones of the skeleton can be dragged and dropped back into the skeleton as a quiz.
DNA collection methods
By Dan Mader
This learning object will define DNA collection and methods
Collecting Biological Evidence
Explore how to collect a fresh or dry blood specimen and prepare it for the crime lab.
Collection of Entomological Evidence
Learners view the scene of a suspicious death and select the evidence that needs to be collected.
Sequencing Impacts Using Radial and Concentric Fractures (Screencast)
Learners examine radial and concentric fractures in glass to determine the sequence of the impacts.
Using an Evidence Bag
Explore how to use an evidence bag including how to open it, place items inside, and seal it for the crime lab.
Collection of Entomological Evidence Test
A crime scene photo for determination of time since death. The student will need to collect the evidence into the correct item.
Aspergillus in the Property Room
By Vickie Brugger
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.
DNA Collection Methods Corrections
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.
Materials for Bloodstain Pattern Mapping, Preservation & Documentation (Screencast)
This learning object describes the equipment and supplies needed to document bloodstain patterns.
Forensic Lamp Examination (Screencast)
By Timothy Austin
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.
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.
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.
