No Class Tonight

All right, folks are still working on their buffer projects. And a handful of students reported they will not make it into class tonight. Se here is the plan:

The purpose of tonight's class was to meet with you guys to ensure your free-choice projects were do-able. We will still do this, but there is no need for everyone to make the trip in. I will be on Meebo during class time (http://libguides.uta.edu/geol4330) and will be on email responding to the free-choice project ideas and in-between will be grading the buffer projects. Should have those graded by Saturday and will send out the grades on them this weekend.

For those still working on Buffer Projects (yeah I am talking to you) get them in by midnight tonight. Use this class time to finish up what you need to and as I said, I will be on Meebo most of the day today and definitely from 6-8pm tonight.

(For those of you who actually read to the bottom of this post, I also am feeling quite unwell and weak at the moment.)

Email to me your topic (been at uta) for your free-choice project. Email by start of class Thursday.

Include the following:

1. Topic
2. Data Sources you Know How to Obtain
3. Data Sources You Are Unsure How to Obtain
