KIDS DISCOVER ELECTRICITY 1

Power Vocabulary is a systematic and individualized approach to vocabulary developmentthat enables teachers to assist students to improve their reading comprehension skills.Power Vocabulary consists of two word groupsspecialized and general-usage words.

Specialized words label conceptsthat support subject matter. Thesewords are the technical vocabularyof a content area. In science,specialized words includebiodiversity and predator. In history,specialized words includehieroglyphic and chariot. Specializedvocabulary also includes words weuse every day that take onspecialized meanings in a particularcontent area. For example, the wordbill takes on different meaningswhen we talk about money (dollarbill or electric bill) than when wetalk about government (a bill thatbecomes an act or a law).

General-usage words are the wordsthat have widely acknowledgedmeanings and that hold the contentof a passage together. These wordsare selected because some readersmay not be familiar with them.Examples of general-usage wordsare morose and diligent.
