HOW DO WE KNOW – DEMO DAY Tuesday 2/9

HYDROGEN AND HELIUM SPECTRUM IF YOU SAW THESE SPECTRUM COMING FROM A STAR, WHAT PART OF ITS LIFECYCLE IS IT IN?

WHAT WOULD IT MEAN IF YOU SAW THIS COMING FROM A STAR? Could you use this to tell what elements are being made? Could you use this to tell what part of the lifecycle it is in?

PEOPLE ARE PROTONS

REWIND… HIGH MASS STAR  I0A I0A

 You will work with your table partner  Each pair we be assigned a low mass star OR a high mass star.  Using pp of the text you will create a diagram to highlight the life cycle of your star.  Each stage must include at least 2 details about the star in that stage.  You may use the class computers for images  The poster must use at least 4 colors.

 Scoring Rubric:  4 or more colors (2 pts)  Artistic/Organized (2 pts)  2 or more details at each stage (4 pts)  Includes the following stages (7 pts)  Nebula  Protostar  Main sequence  “Giant”  Planetary nebula OR Supernova  White dwarf OR neutron star  Black dwarf OR Black hole

 With a partner…  Create a mini-poster, due at the end of the period.  One team makes a low mass star, the other a high mass star.  Must use at least 4 colors.  May use a computer to help with visuals.  Also (ec) use the book pg  When you finish.

HIGHLANDER SHEET 1/8/15 Objective/ SWBAT: Determine the central idea of an article using evidence. Responsibilities: Finish Reading assignment. Grade posters.

 Read Pages  Write a 1 pg CER.

1. Claim - What is the article about? Identify the central idea. 2. Evidence - Why do you think its about that? Support the central idea with evidence. 3. Reasoning - What do you think it means? Be sure that your analysis tightly connects evidence to central idea.

 Grading Posters…  Use the rubric to grade your team’s opposite poster (if you made a high mass poster, you will grade a low mass poster)  After your group’s posters are graded, switch with another group.  Each poster needs to have 2 grades on them.
