We are big fans of Candlewick's "Ologies" series, which include Dragonology, Egyptology, and Wizardology. The fanciful mix of history and fantasy in these books is coupled with an inventive design that includes messages hidden inside envelopes, behind flaps, in glued-in booklets, and more. We made our own Mermaidology books. Shown here are details of pages about "Mermaid Society," by Isabella, age 8, and Ruby, age 7. The girls spent three hours on this project, engaged not only with the visual side, but with the writing and mythologizing.
