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 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.

A human skeleton test will be taken by students. They will need to label all bones of the skeleton.

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.

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.
