CHANGES

``All things go through changes as they grow,'' concludes this simple book using attractive color photos to compare fiddleheads to ferns, a blue sky to a cloudy one, the same trees in four seasons, eggs to birds, and finally a pregnant woman to a growing child. Adequate to develop the concept with young children, but weakened by carelessness in the text: milkweed blooms in June or July, not spring, and corn has usually finished growing before autumn.
