WRITING CHEMICAL PRESENTATIONS

1. WRITING CHEMICAL PRESENTATIONS WRITING AND CREATING A POWERPOINT VERSION INTRODUCTION

2. Writing Writing depends on aim of presentation:

3. Writing Research-based. Plan and write as for a research paper: • Title • Summary of contents (in place of abstract) • Introduction (with posed questions) • Methods • Results and Discussion • Conclusions, acknowledgements, etc

4. Writing Non-research- or topic-based. Can be written in analyticalor argumentative style: • Analytical: write as a sequence of interrelated sub-topics • Argumentative: write as a critical assessment of theory or current ideas regarding the topic

5. Writing Carry out the following steps: • Choose a subject and plan content • Write • Decide on illustrations for PowerPoint presentation (figures and tables) • Create the PowerPoint slides of these • Create the remainder of the PowerPoint slides (title, content or outline, supporting slides, conclusions, acknowledgements, etc) • Control number of slides for your needs

6. PowerPoint as a Presentation Aid • In a presentation, PowerPoint is a visual aid, and as such, is best for illustration, rather than text.Used the right way, it can improve • Effectiveness of presentation • Audience perception • Speaker confidence

7. Strengths and Weaknesses of PowerPoint • Good for visual information (figures, charts, schemes, structures, tables, etc) • Not so good for text • Not good for spontaneous discussion • Can replace structure of presentation rather than support it

8. Creating PowerPoint Slides First steps. Decide: • Number of slides. Depends on duration of presentation and audience experience • Extent of background and depth needed. Depends largely on audience • Organization of slides per section of presentation • Individual slide design. See next

9. Creating PowerPoint Slides Design: text slides (general) • Use minimum of text – stick to ~6 lines with ~6 words per line • Avoid full sentences • Highlight key words • Do not put too many ideas on one slide

10. Creating PowerPoint Slides Design: text slides (fonts and formats) • Use clear fonts – preferably sans serif types, like Arial or Helvetica • Use 28-32 pt fonts in general (smaller fonts occasionally) • Use simple formats, but if complex, ensure it is elegant • Don’t overdo animation

11. Creating PowerPoint Slides Design: text slides (colors) • Dark letters on a white or pale (e.g. cream or grey) background are fine • Color variation within a slide is not necessary, but can be done. In which case watch colormatch • Use plain background, rather than gradation background

12. Creating PowerPoint Slides Design: text slides (colors) • Light letters on a dark background is fine • Color variation can be used • Be careful of color matches (see next) • This style is thought best for large audiences

13. Creating PowerPoint Slides Design: text slides (colors) • In dark letter/light background slides, avoid pale letters • In light letter/dark background slides, avoid red-green combinations (see example, next) • Be sensitive to weaknesses of other color combinations

14. How Reactions Take Place • Chemical reactions are due to the collisions of molecules. • Some collisions result in bonds being broken. • Some of the fragments can reform into other molecules.

21. Creating PowerPoint Slides Design: illustrative slides (figures, equations, etc) • Keep as simple as possible • Think large. Details that are too small won’t be seen • Use minimum number of labels • Use PowerPoint to draw - or import from Excel, OriginPlus, ChemDraw, etc

22. Creating PowerPoint Slides Design: illustrative slides (figures, equations, etc) • Simplify imported figures to fit ppt slide, if necessary • Likewise condense or simplify imported tables • Fill in verbally any footnotes or labels missing from figures or tables

23. Avoid Designs like Next Slide?

24. Fig. 6.11 Bond angles and Geometries • A lone pair of electrons is intrinsically more repulsive than a bonding pair, since no bonded atom draws electron density away from the atom. • The bond angles, HXH, of CH4, NH3, OH2 decrease 109°, 107.5°, 104.5°.
