By looking at the last few slide, watching this video or by looking up how our sun formed by googling it, summarize the formation AND fate of our sun.

Don't forget to use the words "proto-star," explosion (a stellar explosion is either a nova or supernova), nuclear fusion, nebula (gas cloud), red giant, white dwarf in your summarization.

*After you type your summarization, quizizz marks your response "correct" for now but Ms. LaCross will be looking at your answers for an actual grade.
