The Oral Presentation

You will deliver a poster presentation of the identification of one of your unknowns to the class during the last laboratory period. Your poster should outline all the steps that you carried out to determine the identity of your unknown and the conclusions that you were able to draw from each procedure. Sample posters from a previous class are located in the display case in the hall outside the organic lab room. You will be graded on the quality of your oral presentation as well as the visual and content quality of your poster.
