Hertzsprung-Russell Diagram Star Project

 

You and two other students will create a Power Point Presentation and a handout about a specific star class.  The Hertzsprung-Russell Diagram is an excellent place to start your research.  I have included several sights at the end of this assignment where you can search for the starting information.  The requirements include the following nine slides.  There are two groups with alternate slides, the Temperature/Luminosity Axis (TLA) team, and the Main Sequence (MS) team.  The required slides will be given in order, with the portion that is required only by the Objects Within Diagram (OWD) being marked by an OWD and the exceptions noted by the other groups acronym. (Either TLA or MS).

  1. Title slide – Includes Star class you are assigned, members of the group, “Geospace”, Mr. Cook’s class, 4th Period.
  2. HR Diagram slide – Include an HR Diagram and explain the temperature and luminosity of each group of stars.  Show where on the diagram this class of star belongs.  What is the” main sequence?”  OWD: Where does your star fit on this diagram? TLA: Highlight the Temperature and Luminosity Axis’s.  MS: Mark the main line sequence
  3. Distinguishing Features slide – OWD: What are the distinguishing features of this star, what makes it unique from all of the other stars in the HR Diagram. TLA: Describe the purpose of the two axis (Temperature and Luminosity).  MS: Describe what the Main Sequence is and why it is important.
  4. Origins slide – OWD/MS:Briefly describe how a star within each of the star classes was created.  OWD:What is unique about how this class of star was created? TLA: Biography of Mr. Ejnar Hertzsprung and how he created this chart.  MS:  Do stars transition from one type to another, and if so, in which direction?
  5. Composition slide – OWD: What elements does this star contain?  What is its age?  How long does this star exist? Compare this to the life expectancy of a star in each of the other classes of stars.  Was your class of star ever in a different class?  What class of star was it?  Will your class of star ever be a different class of star?  What class will it be?  If you looked through a telescope and saw this star, what would be its distinguishing features?  TLA: Biography of Mr. Henry Norris Russell and how he created this chart.  MS: Give a detailed description of any transitions of stars along the main sequence and into or out of this sequence.  Include changes of temperature, luminosity, chemical structure, etc.
  6. Future slide – OWD: What will happen to this star at the end of its stellar life?  What will eventually happen to the remnants of this star? TLA: How are Hertzsprung Russell Diagrams used? MS: In general, what happens to a star at the end of its stellar life?  Can stars “fall off” the main sequence?  What happens to them if they do?
  7. Stars in this class slide – OWD: What star(s) do we know that fit into this class or class of star? TLA: What are the classes of stars within the HR Diagram?  MS: What is the difference between the smallest star and a planet like Jupiter?
  8. Additional bits of information slide – What additional bits of information do you have about this class of star.
  9. Bibliography slide – Proper format

A one page, double spaced 12 point Times-Roman font summary will be available when you present

Schedule:

  1. 19 October, Tuesday:  Research in N110
  2. 21 October, Thursday – Review of Quarter Exam
  3. 25 October, Monday – Research in N110 (must show Bibliographies by end of this period (Drop presentations into my folder before 8:00 AM on Tuesday (26 October).
  4. 26 October, Tuesday – Class Presentations

 

Grading

Each slide is worth ten points, except Bibliography which is a go/no go slide, depending on how it meets the standards.  One page summary of what you have learned is worth 20 points
