(4) 4-6 Illustrated by Elisabetta Ferrero & Gary Hincks. Harris uses crowded double-page spreads to present information about ocean layers from seashore to ocean trenches, beginning with a helpful cross section of a fictionalized ocean floor. While the focus is on animals that inhabit the various ocean levels (especially in color illustrations with keys), there are text asides that include facts about physical and geological science topics. Bib., glos., ind.

(4) 4-6 Illustrated by Sebastian Quigley & Gary Hincks. In a cramped design, labeled diagrams, paintings, charts, and a sparse, largely error-free text introduce various astronomical objects in our solar system. With two pages per topic, basic facts, such as atmosphere, composition, and relative size and distance, are relayed. Though gimmicky, a cutaway center portal shows, with a turn of the page, the planets' placement in relation to each other and to the sun. Bib., glos., ind.
