Before Watching
-
Ask students what kind of objects they see when they look up
into the sky. Review the visible objects students might
see—such as stars and planets—as well as the ones
they probably don't—including galaxies and supernovae.
Discuss what a light year is and tell students that the farther
away that astronomers detect radiation, the closer they are to
seeing what the beginning of the universe was like.
-
Have students record how scientists in the program react to the
news of discoveries. Do scientists dismiss them or find
discoveries exciting?
After Watching
-
Discuss the benefits or drawbacks to having different approaches
to measuring the universe. What are the advantages or
disadvantages to the competition among scientists to be first in
a discovery?
-
Review students' observations about how scientists in the
program approached and interpreted their data and the data
collected by other scientists. Why might scientists react
differently? How do scientists deal with different
interpretations of the same data?
