Learners examine how fluid enters the inlet of a hydraulic pump because of atmospheric pressure and how pressure is created at the pump’s outlet. This object includes audio.

Learners view animations and video clips showing how power is transmitted from one energized coil to another.

In this screencast, learners examine the interaction between a conductor that represents a motor armature and a magnetic field that represents a motor’s main field. This interaction causes the shaft to turn.

In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.

In this animated object, learners compare the mode of action of steroids with the action of amino acid-based hormones.

In this animated activity, learners view the various hand, arm, and shoulder muscles in action. The students test their knowledge of the location of the muscles in a drag-and-drop exercise.

In this screencast, students identify various muscles of the face and scalp and see them in action.

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

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

In this screencast, learners read descriptions of the actions of the superficial skeletal muscles and see their locations.

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

In this learning object, you will learn about four blood osmolality and volume regulators, their sites of production, their sites of action, and the results of those actions.

By the end of this module, you'll be able to:

- Identify actions that can reduce biosecurity risk

- Develop a biosecurity action plan for a farm

- Select the most cost effective strategies

In this learning activity you'll explore how to change a decimal to a fraction and learn a method to visually check the fraction for accuracy.

In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions, which contain addition and/or subtraction, to their simplest form. This activity has audio content.

In this learning activity you'll identify fractions and view illustrations of fractions.

In this learning activity you'll outline a conversation using the transactional communication model. The print and Email function has been disabled. You may take a screenshot of the last screen if needed.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

In this learning activity you'll view a graphical layout of the transactional communication model.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.
