In this interactive object, learners review respiratory system terminology and then match the terms with their definitions.

In this learning activity you'll match introductory sociology terms on culture with their definition.

Students identify the meaning of urinary system word parts to analyze and define medical terms.

In this interactive object, learners read the definitions of prefixes and suffixes that relate to the digestive system. They then use this knowledge to combine word components to form medical terms.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

In this video you'll study the structure of the cell membrane and construct it using the correct molecules.

In this learning activity you'll explore a step-by-step process to solve simple free-body diagrams. They identify forces acting in the x or y direction in interactive exercises.

In this learning activity you'll study the structure of the cell membrane and construct it using the correct molecules.

The learner listens to the pronunciation of medical terms using a "jukebox" to select the terms.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this learning activity you'll explore the physical construction and operation of single-mode and multi-mode fiber-optic cables used in networking.

In this screencast, learners examine the construction of a 7493 IC as mod-2 and mod-8 up-counters. They view how this binary counter can be modified to operate at different modulus counts.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

The learner will be able to read and interpret thread notes from a print.

In this learning activity, you'll watch an animated explanation of the terms class and object as used by computer programmers, and then contrast the differences.

This primer introduces the student to the key terms and concepts associated with the silicon diode.

Students read the terms associated with the Bipolar Junction Transistor (BJT) . They also view formulas for dc current and voltage.

Students examine the drain curves for a JFET. They are also introduced to vocabulary terms and formulas.

In this interactive object, learners read the definitions of the parts of a cell and assemble a basic eukaryotic cell in a drag and drop exercise. A matching quiz involving cell terms and their definitions completes the activity.
