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 use the Empirical Rule to calculate the percentages of data between two data points.

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 calculate the numeric value of an area when given the z scores.

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 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.

Learners convert a number from standard form to engineering notation.

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

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

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 learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.

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.

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

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

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

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

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.
