Final answer:
Use a large, readable font, include bright, stimulating colors, and use visuals and other media per slide to enhance the effectiveness of your PowerPoint presentation.
Step-by-step explanation:
When creating a PowerPoint presentation, it is critical to use a large, readable font and include bright, stimulating colors. These elements help make the presentation visually pleasing and easy to read for the audience. Additionally, it is important to include visuals and other media per slide, such as figures, charts, graphs, photographs, audio, or video, to enhance the effectiveness of the presentation and support the message. However, be cautious not to include too many words per slide, as it can overwhelm the audience and make the presentation less engaging.
