Killara Academy

Stars and Elements

How did the stars emerge and what did they give us? Killara academy students have commenced their Big History course - a survey of 13.7 billion years of history, from the Big Bang to today. 

Students have been learning about the Big Bang, how the first stars were born, and how these stars died in massive explosions that created new elements. Students learnt how stars attracted other stars to form galaxies. Galaxies attracted other galaxies to form clusters, and then clusters came together to form super clusters. The key concepts from our last lesson included supernova, nuclear fusion and elements. Another key takeaway was that when stars die or explode, they release new chemical elements like oxygen, nitrogen, carbon, calcium, and phosphorus. These elements make up most of our human bodies.

Upcoming Killara Academy events include cooking for the homeless in Bondi as well as a university tour of UNSW. Killara Academy is a university preparation program available to students in Years 7-9.
