Part 1: Areas on the H-R diagramFor the following, locate the area on the H-R diagram (either top, bottom, left, right, or center) where you would find each type of star. You will be recording your answers on this quiz. If more than one word describes the area, for example the top right corner, select both areas.Bright starsHot starsHot, Bright starsCool, Dim starsSun-like (type G main sequence stars)Part 2: Plotting StarsMark/label each of the following on the H-R diagram and label it as indicated.Please note: You will need colored pencils (blue, red, yellow) in order to receive full credit.You will upload your finished image to this quiz. Please make sue you add steps 9 & 10 (to be completed in Part 3).A line showing the approximate location of the main sequence (no label).A blue main sequence star labeled BA red dwarf main sequence star labeled DA sun-like star labeled SA red giant the same color as D and the same brightness as B labeled GA white dwarf the same color as B and the same brightness as D labeled wdA large circle indicating the area where you find the biggest diameter stars, labeled supergiantsA large circle indicating where you would find white dwarfs, labeled white dwarfsPart 3: Getting Information from the H-R DiagramYou will be recording your answers to these questions on this quiz.Stars B and G have the same brightness. Does this mean they are the same temperature? Yes or NoStars D and G have the same color. Does this mean they are the same temperature? Yes or NoWhat is different about star G that allows it to be the same color as D but as bright as B? Explain.How can wd be as hot as B, but so dim? Explain.What will happen to wd as it continues to cool off? Why?Now, please add the following to your diagram from Part 2: 9. Draw an arrow on the H-R diagram to show this change (of wd as it continues to cool).10. Place four dashed lines (- - - - - - - -) on the chart to show lines of equal radius. Explain how you decided what orientation the lines should go.

Instructions undefined Choose a topic of your choice that relates to the materials covered during the fourth and fifth weeks of the course and write a short research paper on it. If you would like to write a paper on a topic covered in the sixth week, you must contact me at least five days prior to the due date to gain my permission. This is your opportunity to explore in-depth a topic that you have a greater interest in than what we covered during the course.  undefined TOPICS:  * A History of Chemical Warfare: Chapter 7 – Chemical Terrorism undefined *How Prepared Are We for Possible Bioterrorist Attacks: An Approach from Emergency Medicine Perspective undefined undefined * Inside the Uranium Underworld: Dark Secrets, Dirty Bombs (2017) undefined * National Strategy for Countering Weapons of Mass Destruction Terrorism (2018) undefined * The History of Bioterrorism undefined * How the Horrific 1918 Flu Spread Across America (2017) undefined * Preparing for a Pandemic Influenza: A Primer for Governors and Senior State Officials (2006) undefined * Pandemic Influenza Plan (2017)
