Imagine you are a star and create a poster and describe

the journey of your life. You can be creative, but it must include facts of a stars

life. Due by Friday 2/27/15

AGENDA

Objective 8.8C

Describe components of the universe, including stars,

nebulae, and galaxies, and use models such as the Herztsprung-Russell diagram for

classification by taking notes and a poster.

• How long a star lives depends on how much mass it began with.

• Small stars use their fuel slower than large stars so they live longer.

Stage 1: Nebula• Stars begin

their lives in an area called a nebula.

• A nebula is a large amount of gas and dust spread out in a immense volume.

Stage 2:Protostar • the early stage of

a stars life.• cloud of dust and

gas is then clumped together by nuclear fusion to form what is called a protostar.

Step 3: Main Sequence Stars

• moves into the main sequence.

• becomes a medium size star

• spends most of its life.

• All other stars are measured in comparison to Sun.

• As stars burn out of Hydrogen gas they move up and to the right.

• they become giants, and supergiants. • Stars are burning Helium now.

Stage 4: Giant and Supergiants

Stage 5: White and Black Dwarf• When a Red

giant starts to run out of fuel, it moves into the death stages.

• A white dwarf-is the blue-white hot core of a dead red giant. These are low mass stars.

Sirius B is a White Dwarf

Sirius A is a Main Sequence Star

OR Stage 5: Neutron• It may also become:

–A neutron star-formed from a supernova (the explosion of a Super giant). This is a high mass star.

OR Stage 5: Black Hole• OR It may become :

A Black Hole- a core of a super massive star that remains after a supernova. The gravity of this mass is so strong that not even light can escape it.

Supernova Black Hole

• Imagine you are a star and describe the journey of your life.
