Practice Classification in Action
Scientists love to classify. When scientific items are properly organized, not only are they powerful tools for scientists, they can also predict yet undiscovered items.
Dmitri Mendeleev, considered the father of the modern periodic table, arranged the known elements of the 1800’s, in rows and columns by similar chemical and physical properties. What he discovered were “gaps” in the table and correctly predicted that yet undiscovered elements would fill those gaps.
Try this simple activity with your child to help him develop an understanding of why scientific classification systems exist and how they are developed.
