For animations, the rules are a little more lenient. The best effect to use is the green “appear” effect. This effect will just make your words appear on the presentation.
When using animations, be sure to have them appear in the right order from top to bottom. Do not use any of the yellow or red animations. They make text disappear or activate an effect at a time when it would not be appropriate for one.
