This four-lesson unit on search skills and critical thinking teaches students how to target and specify their online searches to avoid unwanted results, how to judge whether a link, search result, or website is legitimate or phony and how to find legitimate sources online for media works such as music, videos, and movies. In this first lesson, students learn how to create well-defined search strings and to use tools and techniques such as bookmarking, browser filters, and search engine preferences to avoid unwanted material. The lesson is available in PDF format and includes student handouts.
