1. Black Holes

2. Starter His clip is about a man finding a black hole
Watch the following video clip what is wrong with the science

4. Key Reasons Photon sphere Time dilation Gamma ray emissions
Very low escape velocity required
Very light (surely a black hole would be very dense)

5. Video

6. New Scientist Article Discuss in pairs
What do you think of the article?
What do you think of the title? Why is it written in an informal style?
What is the audience for New Scientist?

7. Report time
- Divide the class into three teams, and assign each team to research one of the black-hole types discussed above.
- You will prepare a presentation based on research, which should include the following:
characteristics of the type of black hole
lifetime of the type of black hole
locations (or suspected locations) of the type of black hole
evidence for existence of the type of black hole
Keep track of the sources for your facts so that you and others can go back to those sources for further information.
Include visuals in their reports.

8. Evaluation
You can evaluate each group’s written product using the following three-point rubric:
Three points: report well-researched, information clearly and logically organized, presentation interesting and lively
Two points: report adequately researched, information sufficiently organized, presentation dull One point: report insufficiently researched, information inadequately organized, presentation poorly prepared
