In this animated and interactive object, learners follow steps that begin with choosing the correct drive roll and include feeding the electrode wire from the spool to the welding gun.

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

In this learning activity you'll review a visual overview of depth measurement using the depth micrometer.

Learners follow steps to size an interior grease interceptor for a commercial dishwasher. This animated learning object presents plumbing code requirements and industry standards. A brief quiz completes the activity.

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.

Learners examine the function of the analog wattmeter to measure true power, how it is connected in a circuit, and how the internal components develop a measurement. A brief quiz completes the activity.
