In this learning activity you'll explore the history behind gage blocks.

In this learning activity you'll test your ability to select the proper gage blocks when making a stack.

In this learning activity you'll identify the consequences of using gage blocks incorrectly.

The learner will understand how to properly use a fillet gage to measure weld size.

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 video shows how to measure the inside diameter of a part using telescoping gages.

This video shows how to measure a hole diameter of a part using small hole gages.

In this animated lesson, students view how an oscilloscope and a DC voltmeter measure the voltage of a half-wave rectifier.

In this learning activity you'll examine how a sine bar is used to measure angles.

Learners examine how metal detectors function. This object includes animation and sound.

Learners compare the three scales used in pressure measurements: gage, absolute, and vacuum. A brief quiz completes the activity.

In this animated object, learners examine how the purge pressure system is used to measure levels of material. A brief quiz completes the activity.

As a welder, you'll need to know how to convert between standard and metric measurements. Try this activity to practice converting between these two measurements. A conversion chart is provided to help you complete this work.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

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.

The learner examines what it means to listen respectively and how to become a better listener.

Learners read how inches of water column is used as a unit of pressure measurement. Practical applications and a conversion formula to psi are included.

In this learning activity you'll observe how switches are used in local area networks to increase data transmission speeds.

In this animated object, learners follow an analogy of water flowing through pipes and valves to see how current increases in a parallel circuit as branches are added.

Learners identify negative roles, match statements characteristic of each role, and relate how they have handled negative teams.
