  3. Georgia Performance Standard 2nd Grade Science Standard Earth Science S2E1: Students will understand that stars have different sizes, brightness, and patterns. a. Describe the physical attributes of stars – sizes, brightness, and patterns. www.georgiastandards.org

  4. What is a star? A gaseous sphere found in outer space. A star is held together by its own gravitation. It emits light through its source of nuclear energy.

  5. Elements of a Star

  6. Physical Attributes of Stars

  7. What causes a star’s brightness? Hhhmmm! I wonder which 2 factors? Take a look at the table on the following slide. Determine what 2 main factors influence the brightness of a star (as seen from Earth)!

  8. Brightness

  9. Did you think about it? What are the 2 main factors? • Distance from the Earth • Luminosity (compared to the Sun)

  10. Physical Attributes of Stars

  11. Sizes Are all stars the same size?

  12. Sizes…(continued) • What do you notice about all of these stars below?

  13. Sizes…(continued) Tell me two types of sizes stars can have. Let’s put them on our physical attributes chart!

  14. Physical Attributes of Stars

  15. Life Cycle of Stars Sun-like Stars (1.5 X mass of sun) Red Giant Stellar Nursery Planetary Nebula Black Dwarf White Dwarf

  16. Life Cycle of Stars…(continued)

  17. Patterns • What patterns can stars create?

  18. Constellations • Stars can form patterns in the sky known as constellations. • Who can tell me the name of a constellation? • This constellation is Orion (the hunter).

  19. Orion

  20. How many stars does it take to make a pattern?

  21. The night sky • What constellations are in the sky right now? KidsAstronomy.com - Earth

  22. Physical Attributes of Stars

  23. What is the sun? • Did you know that the sun is a large star? • Check out this video on the sun! http://www.solarviews.com/raw/sun/sunb.mov

  24. Conclusion • What are the 3 physical attributes of a star? • Tonight, look at the sky and write down what you see!

  25. Glossary • attributes: characteristics • luminous: brightness
