11/8 - How do nanometer, micrometer, and millimeter size objects compare to a kilometer or bigger size objects? From video clip The Scale of the Universe - BI Science - Youtube.com

11/13 - Describe the limitations and capabilities of electron scanning microscope. THIS IS A BUTTERFLY! - youtube.com

11/14 - What are the three shapes of galaxies? Which shape is the Milky Way Galaxy (our galaxy)? (Old ES pgs. 582-584)

11/15 - Make a Venn diagram comparing galaxy and solar system. (Old ES 582)

11/20 - Look at the Star Color Table:

  1. According to the table, how are red stars different than blue stars?

  2. What are the 7 colors of the rainbow? (ROY G. BIV)

  3. There are very few really green stars. What color of star is there instead of Green? Why do you think so?

11/26 - Make a Venn diagram comparing Apparent Magnitude to Absolute Magnitude.

11/27 - Tape the H-R diagram into your notebook and then do the following:

  1. Put the title H-R Diagram above it in your notebook.

  2. Highlight or outline the sun with yellow.

  3. Highlight or outline the Blue Giant region in blue.

  4. Highlight or outline the Red Giant region in orange or red.

  5. Outline the area and label where White Dwarfs would be found on the H-R diagram.

  6. R☉ means sun radii or solar radius. Interpret the diagram: How much brighter and bigger than the sun is the smallest Blue Giant? How about the star Betelgeuse?

11/28 - List the following seven objects from LARGEST to smallest: Galaxy, Star, Universe, Supercluster, light-year, Solar System, Planet.

11/29 - Look over the objectives in the Study Guide: Metric, Scale, and Stars. Write down at least 3 questions you have about what could be on the quiz tomorrow.

- Tape the abbreviation list to the back cover of your notebook. Pick out 6 abbreviations you could use when taking notes or summarizing warm-up questions.
