Opening jokes are for comedians only, and you aren't one
Specifications
Each person's talk should be between 5 and 8 minutes. Therefore, a group of 3 will take 15 to 24 minutes. Each person can use no more than 5 transparencies. While it is good to provide general context, at least one aspect of your presentation should go into the scientific details in some depth. Using a figure from a scientific paper is an excellent way to begin this process.
Visual aids:
Use 1 figure per minute at most, & 1 figure per 2 minutes at best
Make every figure interesting
Simplify your figures, and then make them simpler.
Explain your figures in detail (including defining axies)
Use figures as a memory (numbers & words) crutch
Don't read from text figures (face audience & paraphrase).
Use a CONCLUSION or SUMMARY figure to show you're done
Presentation:
Use analogies that are familiar to the audience
The best defense is a good offense (address problems and limitations)

Never ridicule anyone
Questions:
Carefully listen to questions before answering
