The target audience of this learning object is trigonometry students who have already learned what a radian is and have already derived the key values of the coordinates associated with common radian units, but now need to practice finding those values on the unit circle. The student does not need to know the definition of the six trig functions to do this activity.

In this learning activity you'll explore a graphical depiction of a radian for angular measurement.

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

The learner will understand how to use a cause and effect diagram to find the root cause of a problem.

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 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.

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

Students read how to use the DEGREES() function to convert radians to degrees.

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

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

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

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

Brainstorming helps find new ideas to problems. Learn how you can use brainstorming to write a paper, give a speech, or work on a group project. In this video, you’ll explore what brainstorming is and how to use it.

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

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

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

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

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

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

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.
