The learner sees photos of the spark patterns of various materials and their related properties.

Students read information about basic logic gates including the gates' names, symbols, Boolean expressions, pronunciations, and truth tables. They then complete a matching exercise.

In this video, we’ll identify the parts that make up the Bridgeport and learn how it works.

In this interactive learning object, students read about the voltage and current parameters commonly found on a data sheet. A brief quiz completes the activity.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

Learners apply knowledge about how productivity is reflected in people, processes, and goals.

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.

Match the terms with their meanings.

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

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.
