In this learning activity you'll calculate the numeric value of an area when given the z scores.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.

In this learning activity you'll identify and calculate the area under the normal curve specified by given z-scores.

In this learning activity you'll read descriptions of military standards, ANSI, ISO, calibration system standards and audit system reference standards. These topics would be important for the CQT (certified quality technician).

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

In this learning activity you'll review the historical progression of standards to learn what makes a good standard.

In this learning activity you'll play "How to Really Be a Millionaire" to learn the basics of accumulating wealth.

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.

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

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

Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.

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

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

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.

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

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

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

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