Problem I  Fermi Explores the High Energy Universe  Students work with percentages to explore the identities of the 1873 gammaray sources detected by NASAs Fermi Observatory. Topics include calculating percentages from tabulated data. [Open PDF] Problem II  Investigating the Identity of Unknown Objects  Students explore the Fermi catalog of gammaray sources and investigate the statistics of the unknown sources by comparing them with known types in the Fermi LAT catalog. Topics include calculating percentages from tabulated data. [Open PDF] Explain your thinking: Write your own problem  Using information found in the Math Connection problems, the press release or the video program, create your own math problem that involves the Fermi LAT catalog of gammaray sources. Explain why you set the problem up this way, and how you might find its answer. Evaluate your understanding: Challenge Problem  A followup survey was performed on 11 of the unknown sources in the Fermi/LAT catalog. Use this data to estimate how many unknown sources remain in the catalog. Explain how you arrived at this answer. [Open PDF] Answer: The answer to this problem is provided in the PDF.
