Publisher Description

Entries with definitions of basic scientific terms are accompanied by illustrations, "Did You Know" sidebars, and explanatory notes.

A brand-new, fully revised edition of this outstanding resource for students in grades 6-10 includes hundreds of new words, abundant example sentences, lively feature notes and an all-new full-color art program.

In an updated edition covering a wide variety of scientific fields, more than four thousand entries with definitions of basic scientific terms are accompanied by illustrations, "Did You Know" sidebars, and explanatory notes.

For the first time, the editors of the acclaimed American Heritage(R) Dictionary have applied their efforts to word usage as its own subject. The result is this practical guide that includes chapters on grammar, style, diction, gender, social groups, pronunciation, word formation, science terms, and a subject and a word index.

A conveniently sized paperbound print dictionary for upper grades in high school, and for students in community colleges, junior colleges, and four-year colleges, written with clear defining language. The focus is squarely on vocabulary and definitions. The sophistication level is greater than that of the Student Dictionary. Great for those without ready access to electronic products.
