Star formation
Storyboard Text
- 1st stage of a star.
- 2nd stage of a star.
- Final stage of a star.
- A star is first formed from an interaction of dust and gas that eventually make the star giving it it's core and source of shining light.
- What elements make up the star?How do these elements change as the star ages?How does nuclear fusion change over time as the star ages?
- Once that has been made the core will begin to combine hydrogen atoms to make helium which is called nuclear fusion which powers the star to keep living and shining. What happens next to a star after that depends how big the star is to begin with.
- Where does the energy of light and heat come from?
- Towards the end of a star life cycle depending on the size of a star whether it's big or small it will come to an end. If the star is small the nuclear fusion will come to a halt and the star will become a white dwarf meaning it stopped producing energy and will eventually burn out like a candle to finally become a black dwarf and be completely forgotten in space. If it's a big star the star will continue to expand creating heavier elements so that way gravity won't stop it from growing but eventually it'll grow too big and explode which is called a supernova and that'll be the end of the bigger star.
- My explanation to the Big Bang.
- The elements that make up a star are hydrogen and helium. The core of a star changes which changes the temperature, the amount of light the star gives off and the size of the star. Nuclear fusion changes as the star ages by either stopping at a halt and not produce anymore or it continues to expand the star even bigger.
- From the core of the star. Some examples of fusion reactions specific to the different ages of a star are the supernova which is when a star explodes because it was too big or when a star becomes a white dwarf and stops producing energy waiting to eventually burn out.
- After the Big Bang the only elements floating in space were hydrogen and helium which only created stars but the stars started to create other elements which eventually led to the whole creation of the Solar System and other places in space billions of years ago.
