Not only do they learn new words, they also develop research skills and confidence in their ability to comprehend the world.

You want to look for ones that are age-appropriate and use language accessible to young(er) readers. Here are a few that fit the bill.

For example, a search for "scientist" yields a number of results, including "Earth scientist," "social scientist" and "political science."

    Each definition also offers a link to an audio file of the proper pronunciation of the word.
