In this learning activity you'll examine how a sine bar is used to measure angles.

In this learning activity you'll calculate sine bar problems.

The learner will use the deceptively simple sine bar to measure angles to minutes or even half minutes.

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

Learners read an analogy comparing mechanical work (in this case, sliding a weight) to that of electrical power. The relationship of work, apparent work, and power factor is developed.

In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.

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

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

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.

Learners examine the seven most common barriers to effective listening and consider suggestions for how to overcome these barriers. This interactive object contains audio.

In this learning activity you'll explore public key encryption and conclude with a short quiz.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.

In this learning activity you'll identify the various parts of a bar graph, read and interpret its data, and calculate the data to solve various application problems.

Learners examine the characteristics of a sine wave and the various ways to describe it including Vp, Vp-p, Vrms, Vavg, and frequency.
