In this animated activity, learners examine a systematic method for converting a decimal number (base 10) into a hexadecimal number (base 16).

Explore how to prevent injuries caused by falling from ladders or elevated heights by looking at the parts of a ladder, ladder safety rules, and personal fall protection systems.

In this animated object, learners read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.

Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.

Learners quiz themselves on the conversion factors within and between the metric, apothecary, and household systems.

Learners examine the differences and similarities between hydraulic and pneumatic systems.

In this animated object, learners examine automated manufacturing systems classified as motion control, batch process control, and continuous process control.

Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.

In this animated object, learners examine how the sensory, motor, mixed, and reflex nerves work in the human body.

In this animated object, learners examine a systematic method for converting a decimal number (base 10) into an octal number (base 8).

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

In this animated object, learners examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

In this learning activity you'll examine a systematic method for converting a decimal number (base 10) into a binary number (base 2).

In this screencast of an old Flash learning object, learners follow along as we sort parasites into divisions and helminth divisions. We'll also identify affected body systems.

Learners view the conversion factors within and between the metric, apothecary, and household systems. A quiz completes the activity.

Learners use this interactive and animated object to examine the use of binary numbers in a programmable logic controller. A brief quiz completes the activity.
