In this learning activity you'll explore units of measurement.

The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.

In this animated object, learners examine how to align a part on the 1808 CMM.

In this learning activity you'll review angles and different types of angular measuring tools associated with manufacturing.

In this learning activity you'll test your knowledge of angular measurement in this 10-question quiz.

In this learning activity you'll review a visual overview of indirect measurement.

Test your skills at reading a ruler.

In this interactive object, learners review how to read a caliper. They then test their skills with eight practice questions.

In this document you'll review photos of different types of drilling tools.

This document is a visual and text description of lathe thread cutting tools.

This review tests the student's knowledge of advanced cutting tools and operations on a drill press.

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

In this quiz, you'll practice identifying hand tools by name.

In this quiz you'll identify common hand tools by their function.

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.

Explore some common hand tools you’ll use both at home and at work.

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.

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

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.

Students identify the parts of a triple beam balance and practice measuring the mass of objects.
