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.

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

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 learning activity you'll solve systems of two linear equations in two unknowns by determinants.

In this animated object, users view how a kanban signals production to start.

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

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

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

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

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

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

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

In this animated object, learners examine how psychotropic medications act on neurotransmitter systems to achieve their desired effect.

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 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.

In this animated object, learners view the "T" and "P" waves and the "QRS complex." A brief quiz completes the activity.

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

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