3. Create a Spiral Galaxy

4. Card Sort – Shapes of Galaxies

5. Monster of the Milky Way

6. Exit Slip





Which type of galaxy is the Milky Way and what does it look like?

How do astronomers classify galaxies?

Announcements:



Creating a Spiral Galaxy Creating a Spiral Galaxy p.94p.94The Milky Way is a Spiral GalaxyToday you will create a model of

a spiral galaxy using sandRecord a picture of your model in

your composition book on page 94 and add “Creating a Spiral Galaxy” to your table of contents

Leave the bottom half of the page for notes on the Milky Way

Creating a Spiral Galaxy p. Creating a Spiral Galaxy p. 9494Spiral galaxies are known for their pinwheel

shapeIn your model, EVERY GRAIN OF SAND IS A

STAR!Our star is the Sun, and planets in the Solar

System revolve around the SunAstronomers 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.

Card Sort: Shapes of Card Sort: Shapes of GalaxiesGalaxiesA spiral galaxy is just one type of

galaxy.Astronomers classify galaxies by their

shape, and that is your job today.Your group will have 5 minutes to

categorize the 9 pictures of galaxies by shape

Be prepared to explain why your group organized the galaxies the way you did.

Card Sort: Shapes of Card Sort: Shapes of Galaxies p.95Galaxies p.95Astronomers classify

galaxies by their 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

Glue your organized galaxies to p.95 of your comp book.

Label and describe the galaxy types.

Add “Shapes of Galaxies” to your table of contents.

Way?

2. Draw the shape of the Milky Way galaxy. Label it.

astronomy?

Copy the questions above into your comp book on page 96. Answer the questions using complete sentences. Add the title “What is a Light Year?” in your table of contents.


Agenda:

1. Do First: What is a light year?

2. Light Years vs. Student Minutes

3. Revise Your Ideas





What does a light year measure, and why do we call it that?

Why are light years used in astronomy?

Announcements:



Light Years vs. Student Light Years vs. Student MinutesMinutesThe distance that light travels in a year is a light year. A light year is a DISTANCE!

You will measure how far you can travel in 60 seconds moving heel to toe.

You will define this distance as a “student minute”

How many student minutes would it take you talk walk from O. Henry to places like Zilker Park, 7-11, the Texas Capitol Building?

Light years are useful because they measure very large distances. Are student minutes a useful measurement for large distances?

Revise Your Ideas – p.96Revise Your Ideas – p.96What is a light year?Why are light years used in

astronomy?

Using what you learned today in our investigation, revise your answers to the Do First questions.
