Learners convert a number from standard form to engineering notation.

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).

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

In this animated object, learners examine the PDF (portable document format), which has become the standard file format in the printing industry for the distribution of printable documents.

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.

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 be introduced to Third Normal Form and you'll design a table following these rules.

In this activity you'll practice designing a table in second normal form.

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

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

In this animated and interactive object, learners view American National Standard and International Standard sheet sizes. A quiz completes the activity.

The learner will recognize standard-position angles and find the reference angle for any standard-position angle.

In this learning activity you'll place given vectors in correct positions on the Cartesian coordinate system.

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

Formulas and Functions in Microsoft Excel

A learning object to illustrate the right way to enter formulas and functions in Excel.

This learning object gives instructors an opportunity to review the definitions of formative and summative assessment and list examples of the evaluations they use. In a drag and drop exercise, they classify a variety of assessment tools as either formative or summative.

Learners follow steps to calibrate a transmitter used in process control applications. A brief quiz completes the activity.

In this animated object, learners examine the formation of ester bonds in the synthesis of lipids using triglyceride biosynthesis as an example. Ester bond formation is described as a dehydration synthesis reaction.

Learners examine animations of the most common transmission signals used in automated systems, such as 4 mA to 20 mA, 3 psi to 15 psi, and 0 to 10 volts. A brief quiz completes the activity.

Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
