In this learning activity you'll explore how port scanning is commonly used by hackers to infiltrate a network and how IT security professionals can detect it.

In this learning activity you'll explore three common network protocols that computers use to communicate in a network.

In this learning activity you'll identify TCP and UDP port states and how they behave during interaction.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

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

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

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls, unconditional jumps, and counters in this learning activity.

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

In this learning activity you'll discover how to evaluate a problem statement using both the MEA and the IP Techniques.

In this learning activity you'll define what a variable is, how they're used in the C# programming language, and how the computer works with variables under the hood.

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

Robotic welding is an increasingly popular tool used in industrial welding applications. Knowing how to program the robot is key. Explore how to improve your programming skills by using if-then-else, calls and unconditional jumps in this learning activity.

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

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 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 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.

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

Learners read how to calculate the MOD number and how it is used.

The learner will understand the basics of machine turning including how a lathe works, the equipment used, and commonly used terms.
