In this animated lesson, students read how reducing the thickness of a food is an important factor in cooling it. They also read FDA guidelines for food temperatures.

In this animated activity, a drill-and-clamp machine is used to show an application of a pressure-reducing valve. Recommendations on how to properly make pressure adjustments are also provided.

In this animated activity, learners examine how an adjustable pressure-reducing valve can produce a pressure that is lower at its output than at its input.

In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.

In this interactive object, learners sort veterinary anti-inflammatory and pain reducing medications into categories. They also complete an exercise involving trade names.

In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions so that they can then be multiplied. This activity has audio content.

In this interactive object, learners follow step-by-step instructions for reducing algebraic fractions, which contain addition and/or subtraction, to their simplest form. This activity has audio content.

In a series of three interactive exercises, learners explore the relationship between process cycle time and defect detection, and between process cyle time and smaller batch sizes. The techniques of lean/JIT are applied to achieve the continuous improvement (kaizen) goal of reducing inventory by pursuing one-piece flow.

Learners follow step-by-step instructions for dividing algebraic fractions. They begin by reducing the fractions to their simplest form. Immediate feedback is provided. This activity has audio content.

Learners look through a telescope to see what a company chooses to focus on when making decisions about productivity, reducing waste, retraining, solving problems, and motivating employees.

In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.

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.
