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 interactive object, students view the various positions used during medical examinations. They then match the names of the positions with the correct images and with their descriptions.
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.
How Adding Parallel Branches Increases Total Current
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 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.
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.
In this animated object, learners examine three data compare instructions used by programmable logic controllers (PLCs). A practical application to show how these instructions are used in an industrial setting is provided.
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.
