THE INVENTION HUNTERS DISCOVER HOW LIGHT WORKS

The troupe of wacky, peripatetic invention collectors returns for a fourth adventure.

Having in previous episodes failed to comprehend machines, electricity, and sound (each explained with infinite patience by the children they encountered), four doofus scientists now crash their flying Museum of Inventionology outside an elementary school in order to investigate light. After storming the nearest classroom, they surprise a bespectacled kid, who patiently explains what a prism, magnifying glass, crayon, camera, and television are, respectively. As the child talks, the explanations scaffold upon one another. In one instance the discussion of how a prism bends light leads naturally into a talk about how a magnifying glass changes how that light does or does not come together. Each explanation is accompanied by supporting information, examples, diagrams, and historical notes with dates. Alas, by the end the Invention Hunters are no wiser than they were when they began, but young readers may have reaped the benefits. Silly art and jokes abound, perhaps to a lesser extent than in previous outings. Still, with adults as cheerfully clueless as these, it’s hard not to want to see them louse up more kinds of science in the future. The Invention Hunters are diverse; their patient guide in this title has pale skin and straight, black hair.

Readers will cheer the return of these merry, lab-coated schlemiels.
