Learners review the VDR and work six problems. Immediate feedback is given.

In this animated object, learners are introduced to the structure and function of animal cell organelles.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

In this animated object, learners view molecules as they collide and move between two different solutions. They also observe what happens when the temperature of the solutions is raised or lowered.

In this learning activity, you will learn what supply chain management is, four main links that make up the supply chain, and explore examples of how effective supply chain management works.

Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave displayed on an oscilloscope screen.

In this animated and interactive object, learners examine ventilation, external and internal respiration, and gas transport.

Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.

In this interactive object, learners match physiological, mechanical, or other parenteral nutrition complications with the appropriate nursing care.

The learner will understand the two methods used to create a phase shift in current between two windings.
