1. THE SUN!
Imagine going outside on a clear, hot day and feeling the warmth of the sun. What do we receive from the sun? 

2. The Sun

3. Where are we going?
State Standard: 4. F Distinguish the structure and movements of objects in the solar system. (DOK 2)
Sun’s atmosphere (corona, chromosphere, photosphere and core)
Objective: By the end of today, Stingers reaching for the STARS will know the key features of the four layers of the sun!

4. Question of the Day
If just one part of the Sun stopped working, would we still have light here on Earth?

5. They Might Be Giants
Write down facts that you know are true and ones that you are unsure of

6. What is our sun?
Our sun is a star which is (1) 150 million kilometers from Earth
Average, (2) medium sized star

7. What is our sun? Unlike Earth, the sun does not have a solid surface.
Instead, the sun is a ball of glowing gas!

8. What are the layers of the sun?
The inner most layer is the (3) core.
(4) Hottest area of the sun
Nuclear (5) fusion occurs in the core (Hydrogen is fused into (6) helium) and produces nearly all of the sun’s (7) energy

9. quick check for ROCKSTAR status
What does nuclear fusion do for the sun? What does it provide?

10. What are the layers of the sun?
Photosphere is the (8) innermost layer of the suns (9) atmosphere
Photosphere is the sphere that gives off (10) visible light

11. What are the layers of the sun?
When you look at an image of the sun, you are looking at the photosphere.

12. quick check for ROCKSTAR status
What does the photosphere give earth?

13. What are the layers of the sun?
The chromosphere is the (11) middle layer of the sun’s atmosphere
Means “(12)Color- sphere”

14. What are the layers of the sun?
At the start and end of a total eclipse, a reddish glow is visible just around the photosphere. This glow comes from the chromosphere.

15. What are the layers of the sun?
The (13) corona is the (14) outer most layer of the sun’s atmosphere
Corona means (15) “crown” in Latin
Looks like a white halo!

16. quick check for ROCKSTAR status
What is the innermost layer of the sun?

17. quick check for ROCKSTAR status
Where is the sun’s energy produced?

18. quick check for ROCKSTAR status
Which of the sun’s layers produces visible light?

19. quick check for ROCKSTAR status
Why is it usually impossible to see the sun’s corona from Earth?
[The glare from the photosphere blocks out the fainter corona]

20. What layer of the sun do you see in this picture?
[The glare from the photosphere blocks out the fainter corona]

21. What are you looking at in a picture of the sun?
[The glare from the photosphere blocks out the fainter corona]

22. INDEPENDENT PRACTICE
You are going to be creating a model of the Sun and all of the Sun’s layers. Use page to help you out!
Your drawing should include the 4 distinct layers of the sun (Make sure you label them!!!)
On the back of your picture, write me one sentence for each layer…describing what the sun would be like WITHOUT that layer…
For example….”Without the corona, the sun wouldn’t have a white halo around it.”

23. Closing
Who can name the three layers of the sun and SUMMARIZE the key features of each layer?
