Grade 4–6—Originally published in England in 2004, these books marry vibrant photos and drawings to brief explanations of numerous broad topics and subtopics. Spreads include an introduction, fact boxes, and Web site suggestions. Entries are laid out on a background grid that has coordinates and include cross-references to the coordinates of other entries. The references are at times on a facing page or have a weak connection. The "Amazing Facts" running along the bottom of the pages usually lack closing punctuation and are easy to miss and difficult to read as they are set in black type on a dark background. Discovering Science discusses states of matter, elements, electricity, heat, sound, force and motion, time, and more. Actinium is missing from the periodic table.
