This project gives a drawing with steps to complete the activity.

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.

In this learning activity you'll practice reading an inch micrometer.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

In this animated object, learners examine three different types of multivibrators: astable, monostable, and bistable. A brief quiz completes the activity.

In this animated object, learners examine the structure and function of intracellular and extracellular fluid. They also read about the most common electrolytes in the body and complete a matching exercise to test their knowledge.

Discover how to select the correct fingerprint powder, the proper dusting and collecting techniques, and how to fill out an evidence card.

In this learning activity you'll match a scenario to Maslow's Principle of Motivation. You'll understand the differences between each step in the hierarchy.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

In this learning activity you'll examine strategies to help you deal with tricky personal and business communication situations.

Learners examine a table containing the names of common cations and anions.

Learners assess the periodontal status and the health risk factors of a fictitious patient. They also make treatment recommendations in this interactive lesson.

Learners add suffixes to base words to form new verbs in this interactive exercise.

In this learning activity you'll explore various forms of the verb "do."

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

In this animated object, learners evaluate oral directions and compose questions to clarify ambiguities. This activity has audio.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

The learner will understand the two methods used to create a phase shift in current between two windings.

In this interactive object, learners examine the structure and function of the sense of taste.

The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
