From Wax to CrayonsA child wonders how crayons are made and learns about how oil is mined and processed to extract paraffin wax, which is then sent to a factory to be made into crayons. This illustrated narrative nonfiction book includes a map showing oil fields and crayon factories, a glossary, and further resources.

A concluding fill-in-the-blank story based on the concepts presented throughout each book invites budding writers to customize their own fairy tales and imagine how each episode can go from “once upon a time” to Happily Ever After
