Carl Sagan famously stated, "We are all made of star stuff." This statement is scientifically accurate and literally true, not merely metaphorical or poetic. Scientifically speaking, explain what Carl Sagan meant based on what you have been learning about stars. Respond respectfully to at least two of your classmates. Some suggestion for what to look for: Do you agree or disagree with their answer. Why? Is their answer scientifically accurate? Is there something more they could have include to make their explanation more clear?

Please do not post religious or political beliefs as part of your answer. As a science teacher I can only evaluate your scientific understanding of the topics taught in Astronomy.
