The operation and characteristics of an absolute optical encoder used in automation applications are presented.

Learners view illustrations showing the direct dependence of the volume of a gas on temperature and consider the relationship between the Kelvin and Celsius temperature scales.

Learners solve two sample problems for an abstract reasoning assessment.

In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.

In this interactive object, learners review case studies and identify complex arterial blood gases.

In this learning activity you'll identify abbreviations that represent quantities associated with electrical circuits.

Learners read an introduction to arterial blood gasses and then identify uncompensated ABGs.

In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.

Learners choose the meaning of a selected word in a sentence.

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

In this lesson on atomic structure, learners examine how the binding energy of electrons affects light production in certain phosphors used in x-rays.

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 gain an understanding of robot motion control by comprehending the fundamentals of the encoder.

In this learning activity you'll identify the sides of a right triangle with respect to the angles.

In this learning activity you'll identify various types of unshielded twisted pair cables and their networking connectors.

In this learning activity you'll explore how visual perception influences your understanding of unstable figures.

Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.

In this learning activity you'll practice reading and interpreting a paychecks and paycheck stub.

In this screencast, students read about the seven types of intelligence identified by psychologist Dr. Howard Gardner. They then review the type(s) of intelligence of each character in the Land of Oz.

In this learning activity you'll discover how the visual perception concept influences your understanding of unstable figures.
