How can you tell they’ve got it: Where Elements Come From?

If they’ve got it, you’ll see things like: States that the Big Bang produced primarily hydrogen and helium, and that all heavier elements were made later in stars; Explains that nuclear fusion in main-sequence stars converts hydrogen to helium and can continue building heavier elements up to iron; Explains why elements heavier than iron require supernova explosions to form, and describes how supernovae distribute these elements into interstellar space where they become the raw material for new stars, planets, and life. Or just try it together: If your child was told that the calcium in their bones and the iron in their blood were made inside ancient stars that exploded billions of years ago, could they explain the chain of events from the Big Bang to the formation of those atoms to how they ended up on Earth?

Where Elements Come From

Your child knows the atoms in our bodies were made in stars. The Big Bang made mainly hydrogen and helium. Stars and their explosions built the heavier elements.

In curriculum terms

Explain stellar nucleosynthesis: the Big Bang produced mainly hydrogen and helium; main-sequence fusion builds elements up to iron; and supernovae produce elements heavier than iron and scatter them into space — meaning the atoms in our bodies were forged in ancient stars
