The Sun/Life Cycle of Star
Learning Intentions:
1. We are learning to explain the different characteristics of our Sun.
2. We are learning to understand the life cycle of a star.
2
The Sun
3
The Sun
Our sun is a medium, yellow star
Some stars are 8-300 times bigger, some are smaller like the size of Earth
The Sun gives off thermal (heat) energy and light energy
This energy comes from the Sun’s two main gasses: Helium & Hydrogen
All that energy is what makes the sun shine
4
Multiple Choice
How would you describe our Sun?
5
Multiple Select
What type of energy does the sun give off? Check all that are right.
6
Multiple Select
Which two gasses power the Sun?
7
Characteristics of Stars
Our Sun looks like the brightest because it is so close
A star's size, temperature, and distance from us determines their brightness
Color of stars tells you their temperature
Red are the coldest
Orange and yellow are the next hottest (This is our sun which is 9,941oF)
Blue and white stars are the hottest (can get up to 100,000oF)

Multiple Choice
Which color star is hottest?
10
Layers of the Sun
Photosphere: inner layer, gives off the light of the sun we see
Chromosphere: orange/red layer
Corona: outer layer, atmosphere of sun
There are sunspots on that are dark spots on the Sun. Galileo observed them moving on the Sun which means the Sun is constantly rotating
At times the Chromosphere will have an eruption called a solar flare. The electromagnetic energy from this eruption can interrupt Earth's radio communication
11
Multiple Choice
Which is the layer of the sun that gives off the light we see?

Life Cycle of a Star
14
Beginning of a Star
Stars form in a cloud of dust and gas called a Nebula
Gravity begins to pull the dust and gas into a ball
The temperature gets hotter as hydrogen and helium form releasing a bunch of energy
By the end of this, the ball of particles and energy officially becomes a star
15
Multiple Choice
Stars form in a cloud of dust and gas which is called a _______
16
Ending of Stars (SUN)
Our sun is about 4.5 billion years old and is halfway through its "life"
In billions of years, our sun's fuel (hydrogen) will run out
As it dies, our Sun will expand and get bigger. About 170 times it size and stretch to where Mars is
The Sun will cool down and turn red and is called a Red Giant
When all the fuel is gone, the core (center) of the sun will shrink and be called a White Dwarf
17
Multiple Choice
What happens to our sun as it starts to "die"?
18
Multiple Choice
When our sun begins to cool down and change colors, what is it called?
19
Multiple Choice
What is the last stage of our Sun's life?
20
Other Stars End of Life
Bigger stars grow into Red Supergiants as they use up the core's energy
All this energy causes a huge explosion called a Supernova
The leftover is called a Neutron Star
If the star was big enough, the gravity from the core will continue to shrink in on itself and cause a black hole
A black hole is a part of space where the gravity is so strong it pulls anything near it into it and it can't escape
21
Multiple Choice
What is the explosion of Supergiant star called?
22
Multiple Select
What are the two options a bigger star can end up as when it explodes?
23
Multiple Choice
True or false, nothing can escape a black hole.
