Sure,

Baryons = normal matter, i.e. atoms. Punchline is that only 4% of the universe is made of stars.

Dark Matter = fudge factor we need to explain why galaxies rotate the way they do, and clusters of galaxies act the way they do.

Dark energy = even bigger fudge factor used to explain why, on large scales, the universe is not only expanding, but accelerating in it's expansion.
