In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.

In this learning activity you'll read the steps for proper meter placement for the measurement of resistance, voltage, and current.

In this interactive and animated activity, students follow the steps for proper digital multimeter placement for resistance, voltage, and current.

Learners consider the factors that determine how well an inductive proximity sensor can detect an object. Those factors are size, position, and the material from which the target is made. A brief quiz completes the activity.

In this activity, you'll learn how Fitt's Law applies to user experience design.

Learners study the operation of the retro-reflective optical sensor, along with the guidelines that should be followed regarding the target size, reflector size, alignment, and the reflectivity of the target.

In this learning activity you'll explain your placement of five people somewhere withing the circle of familiars chart.

In this interactive activity, students read about the colored stripes on a resistor and interpret the placement of those colors to determine the value of four-band resistors.

In this learning activity you'll review the rules for placement of commas in a series of adjectives and then apply what you've learned in an interactive practice.

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.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
