Ages 4 to 7 years. Nature is full of patterns. Patterns are made up of shapes such as spots, stripes, circles, triangles, and combinations of these. Colours play a big part in patterns as well. Bobbie Kalman's book helps explain how some patterns help camouflage animals or scare predators away, and how certain patterns seem to appear everywhere in nature! For example, spirals can be seen in the formation of flower petals, the construction of many seashells, in ocean waves, and in hurricanes.
