Sample analysis thread using Lynds 1688 (developed in the context of the Lynds Cloud team).
An adaptation of "Working with L1688" above, with specific application to our project.
First draft of Science Abstract:
We used archival Spitzer data to look for new young stellar objects (YSOs) in Cometary Globule 4 (CG4) in Puppis. CG4 is approximately 1300 parsecs and one of about 30 cometary globules in the Gum Nebula, many of which are known to be forming stars. These globules are pointed generally radially outward from the center of the Vela OB2 association, which is also forming stars. CG4 is dramatic in appearance, and that has brought it to the attention of both scientists and the public. Our team used archival Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) data and 2 Micron All Sky Survey (2MASS) data, as well as optical data obtained by collaborators. We used infrared excess to find nine previously known YSOs and additional new YSOs in this region. We will primarily use infrared excess to find new YSOs. We used available data to attempt to determine legitimate cluster members, and to separate CG4’s YSOs from other objects with similar spectral energy distributions (SEDs). This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by the Spitzer Science Center (SSC).
Please edit as you see fit.
Luisa's edits: We used archival Spitzer infrared data to look for new young stellar objects (YSOs) in Cometary Globule 4 (CG4) in Puppis.

CG4 is dramatic in appearance, and that has brought it to the attention of both scientists and the public. Our team used archival Spitzer InfraRed Array Camera (IRAC) and Multiband Imaging Photometer for Spitzer (MIPS) data, combined with 2 Micron All Sky Survey (2MASS) data as well as optical data obtained by collaborators. We used infrared excess to investigate the properties of previously known YSOs in this region and identify additional new candidate YSOs in this region. This research was made possible through the NASA/IPAC Teacher Archive Research Project (NITARP) and was funded by the Spitzer Science Center (SSC). rationale for my changes: occasional missing words/wordsmithing. the stuff about radially pointing is indeed true, but not strictly relevant to the abstract (tho' it's appropriate for the main body of the poster in the introduction). 'we will use' = lingering sentence left over i think from editing, since it is redundant with prior sentence. stuff about separating YSOs from contaminants absolutely true, but is implicit in the statement that we've identified YSO candidates -- of course we've attempted to weed out contaminants. there should be some text on that in the main body of the poster, though, for sure.
Also, send Chelen the names of all additional authors to be listed. For example, I will write the Breck team as ... Chelen Johnson, Rachel Crump, Anna Laorr, Kayla Mork, Emma Steinbergs, Sara Trautz, Elizabeth Wigley, Sally Caruso, Heather Balenger, Nina Killingstad, Taylor McCanna. We will identify schools with superscripts and a key. (See previous NITARP posters  for an example.)

Here is the Draft Abstract for the Team Wisconsin Education Poster (Viv, WSD, WCBVI and Kevin - no Chelen, I haven't moved...) We welcome comments and edits.
Individuals with disabilities - specifically individuals who are Deaf or hard of hearing# (DHH) and/or blind and visually-impaired (BVI) - have traditionally been underrepresented in the fields of Science, Technology, Engineering, and Math (STEM). The low incidence rate of these populations, coupled with geographic isolation creates limited opportunities for students to work with and receive mentoring by professionals who not only have specialty knowledge in disability areas but also work in STEM fields. For this reason, Yerkes Observatory scientists, along with educators from the Wisconsin School for the Deaf, the Wisconsin Center for the Blind and Visually Impaired, Breck School, and Oak Park and River Forest High School, are engaged in active research with Spitzer Space Telescope scientists within the NITARP project. Our ultimate goal is to engage DHH and BVI students with equal success as their sighted and hearing peers, and share our techniques to make astronomy more accessible to DHH and BVI youth and to generate a life-long interest which will lead our students to STEM careers.
This poster tracks our work with a group of scientists from the Spitzer Science Center during the spring, summer, and fall of 2010. The group coauthored a poster on finding Young Stellar Objects (YSO) in the CG4 Nebula in Puppis. During the project the students, scientists and teachers developed a number of techniques for learning the necessary science as well as doing the required data acquisition and analysis for publishing a poster for the American Astronomical Society. Additionally, collaborations were formed between students with disabilities and their their non-disabled peers to create multi-media projects. Ultimately, the projects created for our work with NITARP will be disseminated through our professional connections in order to ignite a passion for astronomy in all students - with and without disabilities.
