I originally designed this activity as a culminating project for our fourth grade health unit. We spent several weeks learning about the different body systems. I wanted my students to apply what we had learned.
Included in this activity is an assignment sheet with a rubric, a works cited page for students to keep track of sources, and an annotated list of online resources. Rather than make copies of the resource page, I would post it on my classroom webpage and have students start this assignment there. I find that having a list of prescreened resources and a template for sources are a good ways to scaffold beginning researchers.
