1. Presenting Science Molly S. Costanza-Robinson, Ph.D. Middlebury College Environmental Chemistry 270 Spring 2011

2. Outline Presenting Using power point to present Presenting science

3. Outline Presenting Using power point to present Presenting science

4. Presenting Enunciate and project your voice Make eye contact with your audience Avoid nervous habits Reading is not presenting  2 notecards are allowed; try not using any!  Use short, bulleted phrases to keep you on track

5. Rehearse: It helps you… Organize your talk  Is the order of your slides logical?  Do you know what comes next?  Prioritize the information Stay within time constraints  Is your 15 min talk really 25 min?  Can you concisely describe an idea? Stay calm and confident  interruptions won’t throw you off  allows for spontaneous thoughts

6. Consider your audience What do they already know? What do you want to teach them that is new? What will be of interest to them?

7. Consider your purpose To demonstrate your understanding of environmental chemistry To link our classroom learning to a specific case study To guide your classmates through the important aspects of the case study

8. Hourglass Structure Start broad: importance of topic Get more specific: background science Even more specific: methods & results Broaden out again: conclusions & take- home message

9. Outline Presenting Using power point to present Presenting science

10. Slide rules Spend at least 1-2 min. per slide Use <5 bullets per slide Use 24 pt font or larger http://www.cai.cam.ac.uk/students/study/engineering/engineer05/images/sli derule20.jpg

11. Color Choices: contrast is good! BLACK BLUE GREEN RED Don’t use light colors like YELLOW white on black white on blue yellow on blue Don’t use PASTELS M.A. Daugherty

12. Avoid too many words If you have very long sentences being projected on the board, I can guarantee that no one will be listening to the words that you are actually speaking. They will be reading, and your emphasis will be lost. Keep it short Use phrases Force people to listen to you

13. Avoid distractions Although this is cool it distracts from the science Just enough “design” to be pleasing

14. Powerpoint advantage: visuals Photos Diagrams Colors

15. Don’t go overboard M.A. Daugherty A bit much, yes?

16. Outline Presenting Using power point to present Presenting science

17. Scientific Conventions Appropriate units Specific & quantitative Appropriate conventions  Symbols (  m), subscripts (NO 3 ), superscripts (people/km 2 )

18. Tables Help your readers focus on what you deem important

19. Graphs Organic matter Macro-inverts fish Walters et al., Environ. Sci. Technol. 2008, 42, 2316-2322. Annotations can help readers quickly grasp the important distinctions

20. Graphs II Walters et al., Environ. Sci. Technol. 2008, 42, 2316-2322. Way too much data Way too small to see Is there a better Approach?

Site 1Site 6 Trophic position % of ΣPCBs 0 20 40 60 80 100 Di and tri PCBs decrease up the foodchain at both sites Penta PCBs increase up the foodchain at Site 1; trend unclear at Site 6 Trophic Trends for PCB Classes at Two Sites % of ΣPCBs

22. Acknowledgments All the speakers I’ve heard present All the people who have given me feedback on my presentations

23. Presentations 15 minutes + 5 for questions Paper of your choosing, approved by me  Environmental Science & Technology (ACS)  Organic compounds in the environment  Chemistry & Experimental focus Sources beyond the article are expected  Textbooks/online sources to refine understanding of terms, particularly in the Methods section, as needed  at least 2 important sources cited in the Discussion of your article – integrate other literature findings that your article is being interpreted in light of
