Introducing young children to science history offers a way for them to understand the scientific method and the process of discovery. Ideally, they can learn that science doesn’t always take a linear path, and sometimes there are stark reversals.
Take for example, the
discovery of Pluto, its classification as a planet, and its
reclassification in 2006 as a “dwarf planet.” Clearly the definition of
planets has taken twists and turns throughout the years.
I recently completed a book project with illustrator Vance Lehmkuhl with
the goal of presenting the history of Pluto’s discovery and demotion,
as well as a brief history of the discovery of the Solar System’s
planets in general. More information about the book is at:
