Next Fri: Jan 18 Fixed slides • Original ppt is www posted • Your fixed slides due to me by email by Jan 17
Fri: Jan 25 Two Minutes, Two slides • Your talk will consist of two PowerPoint slides. • You must have artwork or a figure on each slide and the artwork must be relevant to the topic being discussed, not window dressing. • Your brief presentation will discuss why the concept is important, and it will give one practical application. • Keep text to a minimum in your slides—bulleted points at most. Imagine how YOU would feel sitting in a seminar with many slides full of detailed text. Your slides due to me by email by Jan 24

TEXT! • short, sweet, bulleted lists • A complete talk • background, results, conclusions • Why important? Problems addressed? • novel techniques described • clear spectra, concise tables • effective transitions Logical flow: Great science poorly presented is diminished. A complete talk usually begins with background, leading into the presentation of pertinent results, and followed by the important conclusions that can be drawn from those results. Background information must give context for the work. Why is this work important to the chemical community or the greater world? What problem(s) is this work addressing? It should describe any experimental techniques or methods that might not be common to the experiences of a typical chemist or your particular audience. Pertinent results should be presented in an organized manner, including clear spectra or summary tables. A running outline is one way to maintain organization during a talk. Plan smooth transitions between a slide just presented and the next one about to appear.
