Today’s Schedule December 6, 2010 • Agenda: • Comp Book Update • Characteristics of Stars • H-R Diagram Practice Homework: H-R Diagram Practice Announcements: Comp Book Check is coming – get your comp book up to date!!! Test next Wednesday! Essential Questions: What characteristics are used to identify stars? How can you organize stars?

  3. Characteristics of Stars December 6, 2010 • Record your number on your paper. • Read your assigned section of the reading and complete the worksheet for your section. • When it is your turn, share your answers with your group. • Complete the questions on the back of your worksheet.

  4. Do Now December 7, 2010 Pick up a worksheet on the front table. Be prepared to share your answers.

  5. Today’s Schedule December 7, 2010 Agenda: 1. Characteristics of Stars 2. Lifecycle of a Star Homework: H-R Diagram Worksheet Announcements: Comp Book Check is coming – get your comp book up to date!!! Test next Wednesday! Essential Questions: What characteristics are used to identify stars? How can you organize stars? How does a star change during its existence?

  6. Star Life Cycle December 7, 2010 Star Life Cycle Describe each labeled stage in the picture of the lifecycle of a star on your worksheet. Use the information in your text book (page 716 – 718.) To describe consider: size, shape, color, what is happening inside, density,…

  7. Exit Ticket December 7, 2010 Use your picture to complete the exit ticket handout and turn in to Mrs. Lees on the way out of the classroom.

  8. Do Now December 8-9, 2010 Take out your Life Cycle of a Star Worksheet and continue working on it. Use pages 716 – 718 to find the information about each stage.

  9. Today’s Schedule December 8-9, 2010 Agenda: 1. Lifecycle of a Star 2. Galaxies 3. Origin of the Universe Homework: Test Review Announcements: Comp Book Check is coming – get your comp book up to date!!! Test next Wednesday! Essential Questions: How does a star change during its existence? What are the types of galaxies? Where in the universe is our sun?

  10. Card Sort: Shapes of Galaxies • Astronomers classify galaxies by their shape, and that is your job today. • Your group will have 5 minutes to categorize the 12 pictures of galaxies by shape. • Be prepared to explain why your group organized the galaxies the way you did.

  11. Card Sort: Shapes of Galaxies Elliptical Spiral Irregular • Astronomers classify galaxies by the following three shapes: • Spiral – pinwheel shape • Elliptical – oval shape • Irregular – no definite shape • Classify your cards again now that you know the 3 types of galaxies

  12. Shapes of Galaxies Spiral – pinwheel shape Card E is an example of a spiral galaxy. Elliptical – oval shape Card J is an example of an elliptical galaxy. Irregular – no definite shape Card I is an example of an irregular galaxy.

  13. Modeling Galaxies Dump a small amount of sand onto your construction paper. Move the sand around to create the shape of a spiral galaxy. What does each grain of sand represent? If this is the Milky Way where is the sun?

  14. Modeling Galaxies In your model, EVERY GRAIN OF SAND IS A STAR! Our star is the Sun, and planets in the Solar System revolve around the Sun which is located on one of the arms of the Milky Way.

  15. Modeling Galaxies Astronomers believe there are hundreds of billions of galaxies in our universe but the exact number is not known. There are about 10,000 galaxies visible from the image of Hubble Deep Field.  There are approximately 100-300 million stars in our Milky Way Galaxy.  At most 8,479 are visible from Earth.

  16. Modeling Galaxies Rearrange your sand to make an elliptical galaxy. What shape does it look like? Make an irregular galaxy. Do all irregular galaxies look similar to each other?

  17. Page 103 - Types of Galaxies A galaxy is -

  18. Page 103 - Types of Galaxies A galaxy is a large group of stars, gas, and dust. The 3 major types of galaxies are:

  19. Page 103 - Types of Galaxies A galaxy is a large group of stars, gas, and dust. The 3 major types of galaxies are: Spiral Elliptical Irregular Draw a picture and write a description for each type of galaxy.

  20. Origin of the Universe Brainpop for Big Bang Theory – be ready for the quiz!

  21. Page 104 - Origin of the Universe • Use the “Origin of the Universe” section on page 722 – 725 to answer the following questions in your comp book. Use complete sentences! • Identify and describe the theory do most scientists agree explains the formation of the universe. • What is the evidence that leads most scientists to agree with this theory?
