Stars that lived & died.
Stars that lived and died before our sun was born created all the calcium in our bones, the carbon in our cells.
SCIENCE BACKGROUND: In the 1930s scientists learned that what lighted the sun was its vast stores of hydrogen being "squeezed" into helium inside its core. Then, in 1957, scientists discovered the sequence by which stars older than our sun (red giants) squeeze the helium into carbon, and how stars at least 8 times bigger than our sun (blue stars) squeeze carbon and helium into all the other chemical elements in the universe. Accordingly, we also learned that only through the death of these stars, and the recycling of atoms they created back into the galaxy, would later generations of stars (such as our sun) be sufficiently enriched in heavier elements to be encompassed by a solar disk that congealed into some rocky planets, and thus eligible for life. 
Connie Barlow has written a new parable, "Startull: The Story of an Average Yellow Star," that celebrates the role that the death of stars plays in the evolution of life: red giants creating carbon; blue stars for other complex atoms. Values include finding one's own gifts, trusting in the ways of the universe, learning that death is natural and important even for stars. The parable is in script form, intended for ADULTS or KIDS to act: 4 characters.
