Objective:

Gather information to answer specific questions

Exploration:

	Read Mission #4
	Review "Important Bulletin from NASA" focusing on the questions to be included in your report.

Explanation:

Your light curve expert team has completed its research on the mystery source. You have visited hyperlinks, constructed a model, graphed a light curve, and compared and contrasted black holes and neutron stars. It is now time to answer the questions from the NASA bulletin. After completing all questions, your team will download a report from a group of experts responsible for analyzing the spectrum. This team will share the results of their investigation of the mystery source.

Elaboration:

• Each member of the team should take out a sheet of paper to answer the questions from the NASA bulletin.

The number below the magnifying glass indicates the NASA bulletin question to which the clue refers.

• After completing questions 1 - 4, your team is now ready to meet with the spectrum team to view their results of the research on the source of the X-ray emission.

• Re-read the link in the NASA bulletin about spectra.

• Read the spectrum team's report

• After reading the report, answer question five from the NASA bulletin.

Evaluation:

Write your report for NASA Goddard identifying the nature of the source of the X-ray emission from the Galactic Center Region. Include in your report your responses to the five questions in the bulletin, as well as a summary of the findings of the Spectrum Team.
