But a closer look at a small square reveals an ever-changing world. . .home to a larger variety of creatures and goings-on than you'd ever imagine, even in just a drop of its water! This beautifully illustrated "you are there" science book--part of the critically acclaimed One Small Square series--is brimming over with fun-to-do experiments and activities for children ages 7 and up.
