Jan Thornhill uses vibrant art to introduce the "nature timescape" to children, depicting from picture to picture how natural scenes change over spans of time ranging from a few seconds to a year. The environments--a tropical coral reef, an African savannah, a meadow in North America, and the South American rain forest--will delight children as they point out what has changed from scene to scene in the before and after pictures. Age 4 and up.
