Learn about the seven common barriers of listening and evaluate a conversation using the barriers.

In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.

In this animated object, learners examine the procedure used to determine the types of terminals on a single-pole, double-throw switch.

In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.

Users study a chart containing numbers 1 to 99 and look for trivial palindromes as well as double and triple iteration palindromes. The reverse and add technique is demonstrated.

Learners examine how language can interfere with clear communication. They select examples of ambiguity, assuring expressions, doublespeak euphemisms, jargon, emotive content, false implications, meaningless comparisons, and vagueness. In an interactive exercise, learners identify ways to overcome these barriers.

Students read how profits can be doubled with the elimination of only a fraction of the "waste" in a company's operation.
