Dichotomous Keys

Well I'm swamped in Microbiology right now. Next week we are going to begin doing unknown bacteria. We will each be given two tubes of bacteria. One will be gram positive and one will be gram negative (basically a simple difference of the anatomy of the bacteria's cell wall.) We will need figure out not only which is positive and negative, but which exact species of bacteria each on is based on a series of tests we have been conducting over the past three weeks. In order to do this, we had to make what is called a Dichotomous Key. A couple years ago when I was in another class I stumbled upon Gliffy.com, a website built for making flowcharts, floorplans, and organizational charts. It's a lot of fun to work with! Here is the dichotomous key I just designed.
