Required science courses can have limited interest from some students. In this article, a physics professor and a science librarian describe methods used to engage non majors in learning about science in a non-threatening way. By evaluating the science on selected web sites, and classifying the sites according to six categories (valid, speculation, controversial, uninformed, misrepresentation, and invalid) and then comparing findings with others in the class, students are simultaneously immersing themselves in practices of the scientific community and gaining critical thinking skills.
