WPF -- Animation Question - wpf

Question

New to WPF. Simple scenario. Can't figure out the right way to do this.
Say I have a single Button. I also have four TextBlocks. I want that one button to trigger an animation (Opacity from 0 to 1) on all of the TextBlocks at the same time.
Thanks in advance!
