In this learning activity you'll read a police investigation report and click on correct report entries in parentheses.

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

In this interactive object, learners follow the litigation process from the filing of a court case through the filing of an appeal. Learners’ choices will move the case in different directions, based on the actions of the parties and the Court. A quiz completes the activity.

Learners test their knowledge of jurisdiction issues by matching case scenarios to the correct court. The cases involve the following courts: Circuit, Small Claims, Probate, District, Bankruptcy, State Appellate Court, Wisconsin Supreme Court, and U.S. Supreme Courthouse.

By the end of this learning activity, you’ll know how to understand, use, and maintain different types of fire extinguishers.

Explore the different types of fires and the extinguishers used for each type.

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

in this screencast, learners examine the formation of radial and concentric fractures as an object breaks a pane of glass.

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

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

A crime scene photo for determination of time since death. The student will need to collect the evidence into the correct item.

Explore how to use an evidence bag including how to open it, place items inside, and seal it for the crime lab.

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.

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.

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.

Learners examine radial and concentric fractures in glass to determine the sequence of the impacts.

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

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.

This activity will summarize the bloodstain evidence documentation process.

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.

Students will learn how to document bloodstains using roadmapping equipment materials

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.

Visualizes direction and quantity of glass particles as the glass is impacted by a force.
