Teaching Suggestion: In The Disappearing Spoon, Sam Kean explores the history behind the periodic table of elements and the effects those elements have on society. It may be helpful to pose these questions and then use these or similar resources to explore what the elements are and how they are discovered. Small groups might report their findings.
