1. Outcome B Sun notes EQ- What are the parts of the sun?
Bell ringer- What are the similarities and differences between Earth and Venus?

2. Answer: Earth vs. Venus Similarities Differences Size
Venus rotates very slowly from east to west; Earth rotates more quickly from west to east
Density
Venus has a thick atmosphere that is mostly carbon dioxide; Earth’s atmosphere is mostly nitrogen and carbon dioxide
Internal structure
Venus is much hotter than Earth; Earth has liquid water on most of its surface

3. Review your notes on the planets
Quiz starts in 5 mins
When done with the quiz turn it in and read at your desk.

4. KWL – what do you know about the sun
With your table create a list of things you know about the sun.
Jobs-
Supply getter (white board, paper towel, expo marker)
Writer
Reporter outer
Supply returner

5. Popcorn Read ch 3 sec 2 The Sun page 68
Around your table number off 1-4
These are the answers you are looking for.
What are the layers of the sun?
How does the sun make energy?
What are the parts to an atom?
What is a sunspot?

6. The Sun A star Provides light and heat to Earth
Made of hydrogen and helium
About 4.6 billion years old

7. Parts reviewed
When you see an image of the sun, you are seeing the photosphere
The sun’s corona, which looks like a halo, can usually be seen only during a solar eclipse
The middle layer of the sun’s atmosphere is the chromosphere
Sunspots are darker areas of gas on the sun that are cooler than the surrounding gases

8. Labeling the sun When you get you sun worksheet put your name on it.
We will label together

10. Create a sun
Your table will work together to create a sun with all it’s parts on the white boards.
I will walk around and quiz you on the different parts.

11. *If time*Magic school bus clip
Look for True facts that they include. You need at least 10. Use this has a review of your planet facts. Test is next week!

13. Chemistry Background Information:
An atom is the smallest particle of an element
Atoms have a core, or nucleus, containing neutrons (no charge) and protons (+ charge)
Electrons (- charge) surround the nucleus
Nucleus: has neutrons and protons
Electrons surround

14. Atoms Atoms can have a positive, negative, or neutral charge
Atoms can change their charge by gaining or losing electrons
When an atom gains an electron, it becomes a negative ion (an ion is an atom with an unequal amount of protons and neutrons)

15. Lists all of the elements
The Periodic Table:
Lists all of the elements
The atomic number is the same number of protons in the nucleus of an atom

16. What causes the sun to produce energy?
Nuclear fusion- the combination of the nuclei of small atoms to form a larger nucleus; releases energy
Atoms are very active and crash into each other
The nuclei become joined, releasing huge amounts of energy
Nuclear fusion occurs in the core, or center, of the sun

17. Who can name the planets

18. The Planets: My Very Educated Mother Just Sent Us Noodles Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune

19. Mercury
Jupiter
Venus
Saturn
Earth
Uranus
Mars
Neptune

20. Inner Planets:
Small
Rocky surfaces
Mercury, Venus, Earth, Mars

21. Mercury
Only inner planet that DOES NOT show evidence of volcanic activity
Smallest terrestrial planet

22. Venus Known as the “morning star” and “evening star”
Earth’s twin due to size and density
Retrograde rotation meaning that it rotates opposite of Earth
Pressure is 90 times greater than on Earth
Atmosphere traps heat from the sun causing a “greenhouse effect”

23. Earth
One of the conditions required for life on Earth is liquid water

24. Earth vs. Venus Similarities Differences Size
Venus rotates very slowly from east to west; Earth rotates more quickly from west to east
Density
Venus has a thick atmosphere that is mostly carbon dioxide; Earth’s atmosphere is mostly nitrogen and carbon dioxide
Internal structure
Venus is much hotter than Earth; Earth has liquid water on most of its surface

25. Mars
May have had conditions needed to support life because there is evidence that liquid water was once present
Spirit and Opportunity rovers found clear geologic evidence of ancient streams, lakes, or floods
Ice is present at the polar ice caps
Large amount of water exists as a gas in the atmosphere
Because the atmosphere is too thin, water cannot exist as a liquid
Atmosphere is mostly carbon dioxide

26. Asteroid Belt Located between Mars and Jupiter
Too small to be considered planets

27. Outer Planets: “Gas Giants” Composed mainly of hydrogen and helium
Atmospheres of the gas giants cannot escape into space because they have very strong gravitational pulls
Jupiter, Saturn, Uranus, Neptune

28. Jupiter Largest and most massive planet
“Great Red Spot” is a huge storm

29. Saturn Rings are mostly made up of chunks of ice and rock
Only planet that has a lower density than water

30. Uranus
Different from most other planets because it rotates on its side

31. Neptune
Astronomers predicted the existence and orbit of Neptune based on Neptune’s gravitational effect on the orbit of Uranus
Very similar in size and color to Uranus
