You need to set the default overlay argument on the frame (i.e., [<+-]).
This instructs LaTeX to create slides that reveal the items in the frame
one by one.

If you want to enable this behavior for all slides, you can place the
following line before the first heading:

#+beamer: \beamerdefaultoverlayspecification{<+->}

See section 9.6.3 of the beamer manual (Action Specifications) for more
details.

Best,
Matt
