dichotomous keys

How do biologists identify new specimens?  They use or create dichotomous keys.  We will practice making keys and reading keys:

A note regarding your quiz.  They have been recorded and will be given back. If you did poorly on your quiz, I will give an opportunity to take another quiz to add to your quiz total.  For example, if you scored 3/5.  You may take another quiz next day (wednesday) after school, on the same topic.  if you get 5/5 in the second quiz, then your quiz total becomes   (3+5) / 10   or a total of 8/10.   There is only one opportunity to do this second after school quiz for every quiz you take.
