Your Learning Goal: After students read about galaxies, they will be able
to chart the characteristics of galaxies.Table of Contents: Characteristics of Galaxies – 56RCatalyst(56L):What do you think is the difference between a star and a galaxy?

Sort your Galaxy Cards
1. Sort or order the cards based on some trait or characteristic the cards have in common.
2. You can sort their cards into groups based on similarities in the shapes, color of the galaxies, shape, or information on the back of the card.
3. There must be evidence behind your reasoning

! Past and current space missions & discoveries
! The Solar System! Planets! Moons! Comets! Asteroids! Meteors
! Stars and Galaxies WE ARE HERE
! Use the Paired Reading strategy to read the articles on galaxies.
! While you are reading, make sure you look for information about spiral, elliptical, and irregular galaxies.
! You have 10-15 minutes
! Person A reads one paragraph to Person B! Person B listens carefully and summarizes
the main point of that paragraph
! Person A and Person B switch roles. ! Person B reads one paragraph.! Person A summarizes the main point of the
paragraph
! Use the reading to find the characteristics of the different galaxies.
! Record the information on your T-chart in your notebook.
Some things to look for:! composition?! shape?! size?! type of stars? ! color(s)?! examples?! other distinguishing features
! Galaxy J082354.96, spotted by the Hubble telescope, is not shaped in a common elliptical or disk pattern. Its official designation is “peculiar” because it has an odd, yet definite shape, most likely from an interaction with another galaxy.
