This article illustrates how a seventh-grade life science unit connects to the Science and Engineering Practices and Nature of Science in the Next Generation Science Standards and used science fair projects as a context for students to solve problems and understand how authentic science is done. We outline how student interests drive the development and presentation of science fair projects and discuss each component of a science fair project to reflect the practices and nature of science and how we support students along the way. The article includes images of students and of their work for science fair projects.
