In this learning activity you'll calculate exponents. You'll practice breaking down exponents and calculating the results.

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

Learners study the effect that pressure has on boiling temperatures. Once a liquid has reached a full boil, additional heat does not raise the liquid’s temperature; however, pressure can vary the boiling point of a liquid. A brief quiz completes the activity.

In this learning activity we’ll learn how the web works by using a Request and Response algorithm.

Learners examine the function of each part of a microscope and follow step-by-step instructions on how to focus on a specimen. They also review the proper use and care of a microscope and test their knowledge in two drag-and-drop exercises.

Learners read how to calculate the MOD number and how it is used.

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

Learners examine how CEC, base saturation, and soil pH work with each other to define plant nutrient availability.

In this learning activity you'll discover how to evaluate a problem statement using both the MEA and the IP Techniques.

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

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

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

In this interactive learning activity, learners explore factors that contribute to the aging process. Learners calculate their age based on biological, psychological, and social experiences. Further reflection allows the learner to consider options and assess issues that impact the aging process.

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

In this learning activity you'll explore how computers connected on a network use Ethernet technology.

In this learning activity you'll play "How to Really Be a Millionaire" to learn the basics of accumulating wealth.

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

In this animated object, learners examine what anxiety is, how it affects people, and ways to manage it.

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.

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.
