This learning object describes the equipment and supplies needed to document bloodstain patterns.

This learning object is designed to show students they types of information that can be imaged from the Electronic Control Module employed by heavy truck engines.

Discover how to select the correct fingerprint powder, the proper dusting and collecting techniques, and how to fill out an evidence card.

This learning object will be used in conjunction with the DNA collection methods learning object. This learning object will cover the errors that were present in the DNA collection methods learning object and how they could be corrected.

In this learning activity you'll practice reading and interpreting a paychecks and paycheck stub.

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.

Test your knowledge of measurement by answers the questions!

The learner will practice reading a Vernier caliper.

Learners get a hit each time they answer a question correctly. A student may test his/her drug calculation skills by playing the baseball game alone, or against another player.
