Instruction slide (delete this when submitted) Each of the following slides suffers from common deficiencies. You may have seen some like this in seminars. Each should be improved. Your goal is to develop crisp, professional, and clear visual aids. Consider how these appear on the big screen. Do consider using color judiciously adding relevant artwork effective scaling adding appropriate labels correct chemical notation Don’t make only cursory changes add any animations for these add additional slides Use the note space of powerpoint to briefly defend your changes for each slide. Justify your changes, explaining how the slide is improved as a result. Slides with a in the lower right corner have some comments from me in the note section for you to consider.
