Introduction and Use of Dichotomous Keys

Description

This activity uses fictitious organisms, called “quozes” to introduce students to the observation of traits and the use of keys to differentiate and identify specimens. Students use two formats of dichotomous keys frequently encountered in the sciences and evaluate which key is easiest to read or follow. After using the keys to identify several different specimens, they are then asked to draw two other specimens using the key to “backward design” them. This kit is complete for 32 students working in pairs.
