Learners study an animated block diagram that describes the function of each element in a closed-loop system used in industrial automation.

Learners examine the elements of a data file memory of an Allen-Bradley SLC-500 programmable controller. A quiz completes the activity.

In this screencast, learners examine the internal elements of a 555 IC and their operation.

Students practice identifying common elements from the periodic table by name or symbol.

Learners examine the basic elements of a machine vision system. A short quiz completes the activity.

In this screencast, students read about the basic organization and structure of the periodic table of elements. Students identify elements as belonging to a group, a period, or neither.

In this interactive object, learners identify the elements of the Windows platform in a drag-and-drop exercise.

In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.

Students read brief descriptions of atoms, molecules, elements, and compounds, and complete a matching exercise that pictures these particles and molecules as pieces of taffy.

In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.

In this animated object, learners examine the parts of a plastics extruder. A quiz completes the activity.

Learners study the descriptions of the three words in a PLC timer: EN, DN, and TT. They then test their knowledge in a brief quiz.

Learners follow the steps for reducing all of the elements of a complex circuit to a single current source and a single source resistance to create a simple circuit. Several examples are given for dc circuits. The conversion between Thevenin and Norton is also presented.

Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.

Learners read definitions of atomic symbols, atomic numbers, and mass numbers and then answer questions about the number of neutrons, protons, and electrons in select elements.

The learner explores the purpose of organizational mission statements and practices writing a statement that contains the four elements outlined.

In this screencast you'll define how perception influences your world view and learn the elements of the perception process.

Learners read the definition of atomic weight and obtain the weights of elements by viewing the Periodic Table and charts that list atomic weights by name or symbol.

The learner will identify the three steps in the writing process and the elements in each step.

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.
