In this interactive and animated object, learners classify a number of diagnoses by shooting a soccer ball into goals marked "Medical" and "Nursing."

In this animated and interactive object, learners examine how blood flows through the heart and lungs. A brief quiz completes the activity.

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.

Learners read how to determine the location of a contour for a specific location given a TIN.

Learners view video clips demonstrating Gram's staining procedure. Correctly stained slides are shown.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.

Learners review guidelines for the proper use of a dial caliper. Illustrations appear throughout the learning object.

In this animated object, learners examine the eight cranial bones, the fourteen facial bones, and the ribs.

Learners follow a methodical approach for the dc analysis of series-parallel circuits.

In this interactive object, learners identify a person's regional body parts.

In this animated object, learners read an introduction to protein structure and function.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

Students identify the various regions of the human body through drag-and-drop exercises.

The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.

Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.

In this learning activity you'll determine what happens to current flow in a series circuit when the resistance is changed.

Learners study an animation of a spring-and diaphragm actuator controlling the opening of a flow valve.

In this learning activity you'll review the structure and function of the different tissues of the human body.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

In this animated object, learners examine water molecules moving through a semipermeable membrane.

In this animated activity, learners examine how organs are visualized in three dimensions. The terms “longitudinal,” “cross,” “transverse,” “horizontal,” and “sagittal” are defined. Students test their knowledge of the location of abdominal pelvic cavity organs in two drag-and-drop exercises.

Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.

In this learning activity you'll review how a short affects current flow and voltage in a series circuit.

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.
