A combination history and activity book covers exploration from ancient Egypt through the era of the Vikings, Marco Polo, the European discovery of the New World, the conquest of the Aztecs, Africa, and more, all the way up to the space age. Every chapter includes an activity of some sort: making an Aztec mask, sea chest, and survival kit, taking an explorer quiz, and finding the North Star. In creating a history book, Tolhurst (Somebody and the Three Blairs, 1991) succeeds in presenting a lot of material simply and clearly; the book is well-designed, with plenty of full-color illustrations. The title is glib, however, for readers won't learn how to become explorers, and some of the activities are forced, or too briefly explained to be meaningful. For readers, perhaps, rather than doers.
