Gr 4-7 Emphasizing how our past is crucial to determining our future, this unique set looks at how technology has changed over the last century and considers how continued technological advancements will affect life on Earth over the course of the next 100 years. Fictionalized futurologist Luna Li, the central character, helps a diverse group of studentsand by extension, the audiencethink critically about what is likely to continue and what could plausibly change in each volume's three distinct sections: "Where Have We Been?" "Where Are We Going Next?" and "By the Year 2120." The graphic format is both entertaining and highly accessible, demystifying potentially complex ideas. While the artwork appears hazy at times, it complements the uncertain nature of futurology. The inclusion of a sidebar at the bottom of some of the pages offers additional noteworthy material without diminishing the primary content.
