1. Parts of the Sun Drill: How many Earths could we fit inside the sun? Objective: SWBAT identify and describe the structures of the sun in order to compare the properties of the sun to the characteristics of the planets. HW: Diagrams due Thursday

2. The Sun is Comprised Of: A round collection of Hydrogen and Helium divided into 3 layers. A dense atmosphere divided into 3 layers.

3. Oct. 16 th of the Sun Drill: Label each part of the sun with the following 3 words: Convection Zone, Core, and Radiation Zone. Is this the atmosphere or main body of the sun?

4. Fusion vs. Fission

6. Other Solar Items Solar Flares Prominences

7. A Description of our Sun The Sun is comprised of three layers: –A dense center that produces heat/energy through nuclear fusion –A middle layer that carries the heat to the exterior portion of sun –An exterior that creates currents that exchange heat with the atmosphere. As the heat is transferred to the atmosphere cooler air is carried back to the middle to heat up again. The atmosphere is comprised of three layers: –The area closest to the sun produces light waves that we see –The middle area that serves as a transition zone –The exterior layer which is the largest layer of the sun’s atmosphere where charged particles continually escape.

8. Definitions Corona: Exterior layer of the sun. The largest area of the atmosphere extending from the chromosphere outward millions of kilometers into space. Visible portion during a solar eclipse. Core: Dense center of the sun where nuclear fusion occurs. Chromosphere: Transition zone of the atmosphere between the photosphere and corona.

9. Definitions Convection Zone: Area beyond the radiation zone where materials are heated, rise to the top, cool, then sink back to the bottom of the zone. Photosphere: Lowest part of the atmosphere and the layer from which light is given off. Radiation Zone: Area of the sun that surrounds the core. Transfers energy from the core to the convection zone.

10. Drill: Compare and Contrast The Sun The Planets

11. Oct. 16 th Parts of Sun Review Drill: What 4 (four) star characteristics can determine from a Hertzsprung Russell diagram? Objective: SWBAT identify key parts of the sun in order to create a model of the sun’s layers. HW: Study

12. Dec. 10 th Review Drill: Will our sun become a black hole? Why or Why not? Objective: SWBAT identify key concepts of stars in order to prepare for Tuesday’s Test! HW: Study

13. Dec. 13 th Review Drill: Draw a diagram of the sun. Include the three parts of the body and three parts of the atmosphere. Objective: SWBAT identify key concepts of stars in order to prepare for Tuesday’s Test! HW: Study
