Looking for Similarities and Differences
Patterns exist everywhere in nature. Early on we learn to recognize them, and they help us make sense of the world. It starts simply – noticing that night follows day, plants have leaves, animals move, and winter snows change to spring rains.
This recognition of repeating events and reoccurring structures and shapes naturally leads to our organizing and grouping things together and inspires us to look more closely. We recognize that insects are animals with six legs, the seeds of evergreen trees are contained in cones, and birds build nests every spring. Careful observation of similarities and differences within groups helps us further classify both living and non-living things. Snowflakes are all six-sided crystals, yet they can be sorted into categories by growth pattern and specific design. Insects, like butterflies, beetles, and grasshoppers, can be separated into easily recognizable orders based on their shared traits. And, while all leaves share a similar function, they can be differentiated by shape and venation patterns. Continue reading Patterns in Nature
