In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

Learners read an explanation of variation and how it can make a process unpredictable. They distinguish between common and special causes of variation in a brief exercise at the end of the lesson.

Learners read an explanation of how to troubleshoot a faulty digital-to-analog converter that has a shorted input.

In this video, you’ll explore the engine lathe, its basic components, and you’ll learn to operate its machine controls.

Learners examine the various classifications of airspace and the requirements to pilot an aircraft there. A quiz completes the activity. This object has sound.

Learners review the process for calculating board feet and use virtual samples to practice the process.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.
