In this learning activity you'll use the Spanning Tree Protocol to correctly set up a loop-free Ethernet local area network.

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

In this learning activity you'll learn what Zip files are, their origins, and how to work with them in Windows.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

Learners examine how metal detectors function. This object includes animation and sound.

In this learning activity you'll explore public key encryption and conclude with a short quiz.

In this learning activity you'll examine the software operation Dynamic Host Configuration Protocol (DHCP), which automatically performs TCP/IP configurations.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

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.

The learner examines what it means to listen respectively and how to become a better listener.

Students read an introduction to the electronic workbench and view a demonstration of how to open a file for circuit simulation.

The learner will understand how to properly use a fillet gage to measure weld size.

Learners view animations showing how hubs and switches work in local area network configurations.
