Learners examine the 10 steps of the accounting cycle. The cycle begins with the analysis of source documents and ends with the post-closing trial balance and interpreting the financial information.

Learners examine the three steps of a processor scan cycle.

In this interactive and animated object, learners examine the duty cycle of a squarewave produced by a multivibrator using a 555 IC (integrated circuit). A brief quiz completes the activity.

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 identify types of activities in the Plan-Do-Check-Act Cycle and watch how the cycle works on the job.

Explore The Study Cycle – an approach that research and experience shows is the best and most efficient way to study

In this learning activity you'll plot GDP data on a graph and determine a phase of the business cycle.

Students read how the Plan-Do-Check-Act Cycle is used in problem-solving and process improvement. In an interactive exercise, students organize process improvement steps following this model.

In this animated activity, sexual reproduction in animals is contrasted with the alternation of generation lifecycle of plants.

In this interactive object, learners study animal estrous cycle lengths. They then test their knowledge in three exercises.

Using text and graphics, this learning activity describes a sine wave, including alternations, cycles, time, amplitude, and degrees

In this animated object, learners examine the different phases of a cell's life.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this animated lesson, the learner examines how a ladder circuit causes the cylinder of a hydraulic circuit to make a single extension and retraction.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.

In this animated and interactive object, learners examine the red blood cell's life cycle and function. A brief exercise completes the activity.
