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

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.

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.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

This learning object shows 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.

In this interactive object, learners view various components of gears and read descriptions of them. Learners then identify the location of each of these components in a drag-and-drop exercise.

Learners view video clips demonstrating acid-fast staining procedures. Correctly stained slides are shown. The learning object includes two matching exercises.

In this learning activity you'll calculate sine bar problems.
