In today’s lessons our students discussed different types of classification. Classification is an important tool in science and it helps us understand certain topics by studying their relationships. We explored why and how scientists use classification, as well as how classification is used in everyday life. We emphasized the many different ways to classify one set of objects; the classification scheme we choose depends on what we are interested in studying.
For today’s activity, the students were given sets of objects to classify. The objects came in various shapes, sizes, colors, and functions. We used our knowledge of dichotomous, categorical and continuous forms of classification and were able to apply these forms effectively to classify these objects using several different schemes, the most popular ones were classifying by placing objects in different color categories and classifying the objects by size.
We also investigated the biological order and class of animals in the animal kingdom. – a categorical heirarchy! The students even had a chance to classify themselves either catgorically, dichotomously, or continuously, and then let the other group guess the rules of their system, an activity they really enjoyed!
