Before Watching
List on the board what students know about black holes. Where did students
learn their information (e.g., science fiction books or movies, articles, news
reports)? Have students rate each fact with how confident they feel about its
accuracy. Add any questions students have about black holes. Organize the class into three groups and have each group take notes on
one of the following topics: how astronomers search for black holes and the
challenges of learning about them, what is known about black holes in general,
and what is known about the supermassive black hole in the center of our galaxy.
After Watching
Have each group that took notes on the same topic present their notes to the
class. Review how scientists determined what is in the center of our galaxy.
What evidence led them to know it was a supermassive black hole? What do
scientists still want to know about black holes?
Based on the information from the program, have students revisit the list on
the board and compare their previous understanding to what they know now. Have
students provide data to support or disprove the facts and answer the questions
listed. Assign teams to research and report back any remaining facts or
questions not answered by the program.
