The Space Between: Finding Dichotomy to Learn About Nature
We humans do some of our best learning through observation. Even those of us who have yet to develop any consciousness surrounding this aspect of our learning process still depend on the powers of observation in learning about the world. Observation is the means of education for that which we cannot experience; while we will never experience what it’s like to sprout from an acorn and spend a season growing slender and leafy, we can watch the process and reflect on what we’ve seen.
While observation is often looked at as a process of watching, it is actually a process in which watching is very closely intertwined with both reflection and comparison, and this is especially true in learning about our surroundings. We observe the changes taking place around us throughout any given season, and we use our ability to reflect on earlier days in the season and compare these memories with what we’re currently experiencing. It is in this balance of experience and some brain-based form of Venn diagramming that our best understandings are built.
This month, our nature table focuses not on a seasonal theme but the idea of dichotomy – a division that exists between two separate groups of things. In biology (the umbrella under which the great majority of our nature table studies fall), dichotomy is also known as bifurcation, a word that refers specifically to the dichotomy of groups that are not entirely separate, but that branch from a shared origin.
While all of this sounds far more complicated than what the average elementary-aged student can wrap their mind around, the idea of bifurcation is much more familiar to most of us than we might expect (even those of us whose ages are still in the single digits). The dichotomous key, a tool with which we identify the scientific name of just about anything on earth, focuses specifically on the differences between items which have shared roots. A basic dichotomous key for tree identification might, for example, begin with the simple question of whether a tree has needles or leaves. While both conifers and deciduous trees fit into the umbrella category of trees, it is only by examining the differences between the two that we are able to narrow down our identification.
Our nature table collection hasn’t changed much this month, because we’ve focused instead on reflection, comparison, the role of perspective, and the identification of dichotomies between the objects we’ve already collected. We’ve compared our treasures (new and old) to each other and to the things we’ve seen in our surroundings, and we’ve compared each day to the previous one in order to reveal the subtleties of seasonal changes. We’re finding dichotomy everywhere, and are discovering for ourselves that no two things are truly the same.
Some books to inspire the search for dichotomy are:
- The Tree Book for Kids and Their Grown-Ups by Gina Ingoglia
- Backyard Birding for Kids by Fran Lee
- A Little Guide to Wild Flowers by Charlotte Voake
- About Arachnids: A Guide for Children by Cathryn and John Sill
- Mammals (Peterson Field Guide Coloring Books by Peter C. Alden, Fiona Reid, and Roger Tory Petersen
