Animating items in your slide show really help to give life to your presentation.
To animate items within a slide first select the "Animation" tab at the top. Then Select what you want to animate, start with the first thing you want to animate, the order these are done in determines the order they are played in. My example is circled in red. Next choose the animation you want, The area where you choose which animation you want is circled in green. After you find an effect you like try out the effect options which have been circled in purple. With the effect options you can change the way an effect acts. Usually you would want to animate everything on every slide. It may take a while, but it's quite worth it.
