Learners read a description of inductors and view examples of inductors in series and in parallel.

Learners mentally manipulate two-dimensional diagrams to visualize the objects in their three-dimensional forms.

Learners choose the meaning of a selected word in a sentence.

Learners solve two sample problems for a numerical reasoning assessment.

Learners solve two sample problems for an abstract reasoning assessment.

Learners solve two sample problems for a mechanical reasoning assessment.

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.

Learners read the definitions of an assumption and a fact. They then provide their own examples of each and compare those to the examples provided.

In this learning activity, learners review the value of health and wellness as it relates to exercise, nutrition, intimacy, and spirituality. Examples of each are identified, and learners are given the opportunity to reflect on how these examples are associated with health concerns in older adults.

The learner studies how electrons travel from one atom to the next. Examples demonstrate how voltage is created by the use of a battery or through magnetism. A quiz completes the activity.

Learners review the basic math operations involving zero, emphasizing that division by zero is undefined. Examples are given.

Learners read an introduction of scalar quantity and vector quantity and force. Examples are given.

Learners read definitions of discrete, continuous, attribute and variable data and view examples of checklist, location and item check sheets.

In the first section of this activity, learners listen to an introduction explaining the importance of setting goals in all aspects of life. The remaining pages list examples of goals and procedures relating to a farming operation.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.

Learners view examples of devices that prevent mistakes from occurring.

Students follow the steps for finding the total impedance for a series-parallel circuit. Several examples are given.

Students read a definition of Kirchhoff's Voltage Law and view examples of its use.

Learners assign oxidation numbers to atoms in neutral compounds and in polyatomic ions. Six examples are worked through in detail, and three problems are provided.

Ions are electrically charged particles obtained from an atom or from a chemically bonded group of atoms by adding or removing electrons. Eight examples illustrate the number of protons, neutrons, and electrons in positive ions (cations) and in negative ions (anions).
