and straightforward, and each spread contains detailed artwork and photographs. The series combines landmark experiments in the history of science with the human element - the great men and women of science. Special features include: demonstrations which re-create experiments and expand important principles; artworks which explain how and why things work; specially built 3-D models which aim to make clear even the most complex concepts; and words and pictures which work together to explain scientific principles clearly and concisely. "Ecology" covers such topics as nature's producers; decomposers; carbon cycles; minerals and soils; and ecological competition.
