This primer introduces the student to the correct method of using complex reciprocals in a TI-86 calculator. The solution of total impedance of a parallel circuit in rectangular form is shown.

Learners read about the role of water, the basic physiology of water balance, and the effects of dehydration particularly on elderly clients. Tips for maintaining proper hydration are presented. In an interactive exercise, students calculate how much fluid a client needs based on his/her age, health, and weight.

This primer introduces the student to the correct method of using the internal memory of a TI-86 calculator.

Students view the formulas to be used to convert a series impedance to a parallel impedance.

Learners study the mathematical calculations used to determine the proper PID values to be entered into a controller using the Ziegler-Nichols Reaction Curve.

In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.

In this interactive object, learners solve additional problems involving total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated.

In this interaction the student is presented with 10 questions on indirect measuring devices and their uses.

Learners read about the U.S. Department of Agriculture's guide for daily food choices. They then recreate the Food Guide Pyramid.

The learners will explore the Errors in Judgment: Barriers to Critical Thinking and how it affects their decision-making processes.

In this learning activity you'll observe how computers operate in a client-server network operating system and consider the advantages and disadvantages of such a system.

Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.

Students review logarithms as they pertain to electronics.

You'll answer a list of questions based on their gender then answer the same questions as if you were born the opposite gender.

Learners take a close look at the information on product labels concerning fat, fiber, and serving sizes. A quiz follows the lesson.

Learners follow the path of a carbohydrate food from consumption through digestion to absorption into the bloodstream. In a matching exercise, students identify the main type of carbohydrate found in four different foods.

In this screencast, students read about the key differences between management and leadership activities. They will review typical supervisory activities as either management or leadership.

In this interactive and animated object, learners examine how dc voltages develop across capacitors that are connected in series and in parallel.

In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.

The student takes a quiz on lathe cutting speeds and RPM calculations.
