Ask those who explain science to the public what an informed citizen needs to know about the scientific method. "Science literacy is an outlook. It's … a lens through which you observe what goes on around you," says Neil deGrasse Tyson, host of PBS's "NOVA" show. Understanding the way scientists find and challenge "truth" about climate change is more important than what is now taught in many science classes. How the theory of evolution arose and was tested is a more interesting and relevant biology lesson than learning the names of cell parts. The scientific method, coupled with critical thinking, is especially important when receiving messages that arrive via social media. Whether it is gossip about a classmate or about a presidential candidate, students should know how to evaluate sources and check on the veracity of the "news."
