The topic of explorers and exploration is commonly taught in the upper elementary grades. Depending on state and local social studies content standards, teachers will develop a curriculum unit on Explorers of Our State for fourth grade students, a unit on Explorers of the United States for fifth graders, and one on World Explorers for sixth graders. The innovative use of online tools and resources can greatly facilitate generative inquiry. Yet for many elementary teachers, finding the time to teach social studies while integrating technology into the curriculum can be challenging. This article describes a project, "Exploring the Explorers," which can be used as a guide for upper elementary teachers when designing a similar curriculum unit. The use of technology is not "tacked onto" other activities; rather, students use technology in purposeful and engaging ways. In this article, the authors guide students in comparing information from different sources--including a website that deliberately misleads the reader with occasional bits of false information. Also included are lessons about evaluating websites from "All About Explorers." (Contains 1 figure and 13 notes.)
