In this learning activity you'll review safety considerations for using hydraulic press brakes.

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

The learner will measure and record dimensions using a metric micrometer to an accuracy of plus or minus .01 of a millimeter.

In this learning object you'll explore wheel markings identifying the major factors in grinding wheel selection.

In this learning activity you'll examine a stateful packet inspection firewall that keeps track of legitimate Internet service requests, also known as dynamic packet filtering.

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.

Meaningful measures administered by learner-centered teachers represent a multiple and varied body of evidence. Match the terms to the definitions to learn about the categories that make up meaningful measures of assessment.

The learner will practice reading a Vernier caliper.

You'll practice converting between units of measure for length in the metric and English measurement systems.
