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.

Discover how to select the correct fingerprint powder, the proper dusting and collecting techniques, and how to fill out an evidence card.

Learners follow a timeline of the criminal law process, clicking on the steps to read descriptions of them. A quiz completes the activity.

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.

Learners watch a short video showing the correct procedure for police officers to follow when making contact with a high-risk vehicle.

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.

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.

This learning object describes the equipment and supplies needed to document bloodstain patterns.

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.

Temp version with colors adjusted for Section 508 compliance

Learners view the scene of a suspicious death and select the evidence that needs to be collected.

Explore how to collect a fresh or dry blood specimen and prepare it for the crime lab.

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.

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.

Learners watch a short video demonstrating the correct procedure for police officers to follow when approaching a motorist after stopping a vehicle.

Learners watch a short video showing the correct procedure for police officers to follow when making a non-approach vehicle contact.

Learners watch video clips demonstrating the correct procedures for police officers to follow when entering and clearing a room.

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.

Students will learn how to document bloodstains using roadmapping equipment materials
