The Chandra X-ray telescope combines an unprecedented spatial resolution of ~ 1 arcsec on-axis with sky coverage of typically hundreds of arcmin2. These features provide a lot of high-quality data on numerous serendipitous sources which are often not related to the primary science goals of an observation. When amassed from hundreds of pointings, totaling thousands of sources, these "bonus" data provide a treasure trove for a wide range of scientific investigations, including active galactic nuclei, clusters of galaxies, main sequence stars with active coronae, and accreting binary systems. The Chandra Multiwavelength Project (ChaMP; http://hea-www.harvard.edu/CHAMP/; PI, B. Wilkes) and its galactic plane analogue (ChaMPlane; http://hea-www.harvard.edu/ChaMPlane/; PI, J. Grindlay) collaborations are analyzing Chandra archival data and conducting optical imaging + spectroscopic follow-up to produce a large X-ray survey. Chandra's combination of depth, hard X-ray sensitivity, positional accuracy, & large number of serendipitous sources makes ChaMP & ChaMPlane unique, and they will remain so for the foreseeable future. This poster presentation is a companion to the lead author's talk in the special session "Research & Education: NSF Astronomy & Astrophysics Postdoctoral Fellowships (AAPF) Program." It further elucidates the points of the talk: an overview of the ChaMP & ChaMPlane; the survey's AGN component; more specifically, a new program at the University of Texas to obtain low-resolution spectra of hundreds of mostly extragalactic ChaMP sources with the 2.7 meter telescope and the 9 meter Hobby-Eberly Telescope (HET) at McDonald Observatory; and finally the education component of the NSF Fellowship -- working with UTeach, an innovative program at UT Austin for training science teachers.
