About Investi-gator
The Investi-gator is another member of the Natural Inquirer family. The Natural Inquirer, for middle school students, and the Investi-gator, for upper elementary students, present science the way scientists most often share their research with each other. That process is the written scientific paper. Each Investi-gator article presents research conducted by Forest Service scientists and their cooperators. All the research in the Investi-gator is concerned with nature or with society’s relationship to nature.
