Description:

Students were provided with drawings of snowflakes and were asked to construct a cladogram of the snowflakes. The drawings were provided by the students themselves during a quiz a few weeks earlier. (The quiz was 1: write your name, 2: draw a snowflake). There were 17 students and therefore 17 snowflakes. Students are asked to construct a character table and determine various character states. Then students construct a second table showing each snowflake and its state for each of the characters. Finally, students are asked to use this to construct a cladogram, as best they can, from their character matrix. Students note homologies and count the steps in their cladograms.
