In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

In this learning object you'll review various types of groups as well as the concepts of rules and norms in groups.

Learners read about the concepts of true power, reactive power, and apparent power, and are introduced to the power factor formula. A short quiz completes the activity.

The current-to-voltage conversion of the transresistance amplifier is examined. The formulas for output voltage and impedance are defined and an example ties the concepts together.

In this interactive object, learners check their knowledge of concepts related to the cost of ensuring quality in manufacturing as they relate to the categories of appraisal, prevention, internal failures, and external failures.

This primer introduces the student to the key terms and concepts associated with the silicon diode.

You'll practice calculating your time with regards to the economic concepts of scarcity and choice and positive vs. normative economics.

Instead of trying to memorize content, the SQ5R technique focuses on understanding concepts and new ideas.

Learners examine the fundamentals of a pulse train. Concepts such as time on, time off, duty cycle, period, and frequency are covered.

Learners tackle this interactive learning object after studying the mathematics of buying. This activity ties together the ideas of net cost, list price, trade discounts, cash discounts, net cost equivalent, and single discount equivalent, as well as the concepts of part, base, and rate.

This learning object is designed to assist students in understanding and interpreting collision evidence found in automotive lamps. In particular, the concepts of Hot Shock, Cold Shock, Hot Break, and Cold Break will be visually addressed.

Learners follow steps to add fractions with different denominators. They also review fraction concepts, do a drag-and-drop exercise involving fraction terms, and add fractions with common denominators.

Learners play a game to review concepts connected with student assessment. The categories on the game board are "General Assessment," "Science Assessment," "Math Assessment," and "Famous Scientists."
