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

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

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

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 the operation of two-way, three-way, and four-way directional control valves used in pneumatic 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 examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

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.

In this animated learning object, learners examine the regulation of inducible operons in bacterial systems.

In this animated object, learners trace the olfactory pathway from the nasal cavity to the olfactory cortex.

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

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.

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

Learners examine the anatomical parts of the lungs.

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

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.

Learners examine the operation of positive and non-positive displacement compressors used in pneumatic systems.

In this interactive lesson, students use critical thinking to determine the best lean manufacturing initiative when solving problems for the fictitious Batchless Manufacturing Company.

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.

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