Knowledge is organised into recurring themed groups (Earth and Its Neighbours, The Book of Wonder, Men and Women, Our Own Country, Things to Make and Do) instead of an A–Z sequence, and each fortnightly part carries a slice of every group. The child therefore reads across disciplines in one sitting and builds a connected picture of the world rather than looking up isolated facts.
Children's own naive questions ('Why is the sky blue?', 'Where does the wind come from?') are posed verbatim and answered in plain narrative prose, so curiosity itself becomes the entry point to physics, biology and astronomy. Because the unit is a single self-contained question, it can be excerpted, reordered and republished indefinitely, which is why the format outlived the rest of the work.
Scientific explanation and moral instruction are fused: every natural mechanism, from the structure of the eye to the orbit of the planets, is presented as proof of a benevolent Creator's order. Alongside this, British history and the Empire are framed as the moral culmination of progress, so facts are delivered already embedded in a confident Christian-imperial account of what they mean.
