Skillful searches are essential for 21st century learning and information literacy. With abundant information at our fingertips it is important to teach and reinforce literate searching.In this beginning search lesson students will take a look at search engines. By challenging students to understand the basics of search and how to understand results they'll learn how they can "drive" a search engine to deliver the results they need.
Inquiry question: How does search work on the web?
- Students will identify the basic parts of a web search engine and define web search terms
