Task:
During the next few days you are going to research information about Black Holes and Quasars.(G2) You will then be asked to prepare a paper answering several questions.
Text reference: Ch 13.6
Procedure:
Day 1 – 2
You will be given time to research the following concepts:
- Black holes
- Quasars
Be sure to keep record of where you find your information.
Day 3
In class you will have time to share your information and start to formulate the answers to the following two questions.
1. What is a black hole and how does it form?
2. What is a Quasar, and how can they be turned on and off?
Optional for extra credit: How can a black hole die?
Final Product:
You are to word process the answers to the two questions and hand them in within three days. Your answer must be no longer than one page single space and 12 font in size. Your references must be cited using MLA format and may be on a second page.
Your answer must be in your own words. Copying and plagiarism will result in a failing grade.
