In this screencast, learners will match the muscle names to their corresponding locations in the human body.

In this interactive object, learners examine standard and metric thread specifications used in engineering drawings. In a brief quiz, they identify various internal and external thread representations.

In this animated object, learners examine the major descending tracts of the nervous system. A matching exercise completes the activity.

Learners identify the major components of an aircraft and the functions of these components.

In this animated object, learners examine the major events that occur at the neuromuscular junction.

In this animated activity, learners explore three major methods of heat transfer and practice identifying each.

In this learning object you'll explore wheel markings identifying the major factors in grinding wheel selection.

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 animated activity, learners examine the two major phases of cell division: mitosis and cytokinesis.

In this screencast, we'll view the 10 major bones of the skull and read a description of each bone.

Students read about Japan and test their knowledge by answering questions. They also locate Japan's major islands and the bordering countries on a map.

The learner sorts a variety of foods based on personal preferences. Those personal choices are then classified by food group. The learner views the charts and reads information about the major food groups.

In this interactive object, learners examine the locations of major body cavities and their protective membranes. A drag-and-drop exercise completes the activity.

In this interactive object, learners review the major parts of the skeletal system by clicking on the correct term as each bone or joint is highlighted on a skeleton.
