NGSS.HS-ESS1-3

The stage in which a small to average mass star has used up its helium and its outer layers escape into space, leaving behind a hot, dense core that contracts. After this stage, it will become a black dwarf.

• Main Sequence

• Red Supergiant

• White dwarf

• supernova

A gigantic explosion in which a massive star collapses and throws its outer layers into space

• Supernova

• nebula

• white dwarf

• Main Sequence

An object in space whose gravity is so strong not even light can escape.

• White Dwarf

• supernova

• neutron star

• black hole

The small, dense remains of a high-mass star after a supernova

• protostar

• neutron star

• red giant

• white dwarf

Where does the NCO cycle take place?

• In small mass stars

• In the cores of supergiants

• in black holes

• in the Big Bang

The stage in the life cycle of a large mass star during which the star increases in size and becomes very bright. It is in this phase that heavier elements up to Iron are formed.

NGSS.MS-PS2-4

A very large star of high luminosity and low surface temperature. They are the phase of a small mass star after no hydrogen is left to burn and only helium remains.
