As a fourth-grade science teacher, the author wanted a project that was (a) yearlong in scope, (b) got her students outside more, and (c) laid the groundwork for a learning progression. In this article, she describes a project in which her fourth-grade students created digital field guides for visitors to their school's nature trail. In the process, the students learned valuable inquiry and technology skills. This was a unique learning experience for the students involved because of the technology used and because of the ability to follow through with a long-term project. Many students who did not have computers at home had an opportunity to use computers for both the research and the creation of the podcasts. (Contains 4 figures and 4 online resources.)
