Learners answer 20 questions about regulations covering the sale of alcoholic beverages in Wisconsin. The questions are presented in a game show format, and immediate feedback is provided. A final score is given at the end of the activity.

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.

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

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.

Students read about the process of hair growth beginning with the joining together of amino acids.

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.

In this screencast, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.

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

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

In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.

In this animated object, students examine the shades that result from mixing primary and secondary colors. Color tone and level are also defined.

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.

This learning object will define DNA collection and methods

In this screencast, learners examine the properties of the hydrogen bond and how the bond changes when hair is shampooed or styled.

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

Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.

In this interactive object, learners identify the different roles generally assumed by teachers and instructional assistants as they form a partnership in the classroom.

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.

Learners answer 20 questions related to discouraging intoxication in an establishment. The questions are presented in a game show format, and immediate feedback is provided. A final score is given at the end of the activity.

In this interactive object, the learner views photos of the interior of a salon and identifies areas that violate Wisconsin safety and sanitation regulations.

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

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

Students will learn how to document bloodstains using roadmapping equipment materials

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 answer 20 questions related to providing responsible customer service. The questions are presented in a game show format, and immediate feedback is provided. A final score is given at the end of the activity.
