The document outlines a content standard, learning competency, and performance task about the formation of elements during the Big Bang and stellar evolution. Students are asked to give evidence for and explain how light elements like hydrogen, helium, deuterium and lithium were formed in the Big Bang, and create a timeline showing the historical development of atoms or chemical elements due within two weeks. A sample video is provided to watch for additional information.
