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.

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 examine the operation of two-way, three-way, and four-way directional control valves used in pneumatic systems.

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

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

Learners examine the anatomical parts of the lungs.

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 read a brief description of the roles of the hypothalamus, emotions, and adrenal secretions during the stress response.

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

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

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

Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.

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 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 trace the olfactory pathway from the nasal cavity to the olfactory cortex.

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

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