Mathematicians say that symmetry has to be identical parts, but nature is never truly identical. However it is far more interesting than geometric shapes! Reading this book, children will become aware of the balance of things in nature. They will delight at amazing photographs of butterflies, beetles, leaves and flowers, fruit, sea creatures, and children. This book will show how a person with arms outstretched has five-fold symmetry like a sea star, and if you drew a circle around his or her body in that position, the navel would be at its center.
We measure time in minutes, hours, days, weeks, months, seasons, years, and in historical dates. We talk about mealtimes, bedtimes, school times, holiday times, and good times.

How do animals and plants sense changes in time? What changes do we see in nature throughout a day, month, and year?
