We combine optical, infrared, and millimeter/submillimeter-wave observations to study a small clump of recently formed stars and the interstellar environment between the galaxies of M81 and NGC 3077. This clump is coincident with an HI emission knot in the Southern Tidal Arm of the M81 system, and is known to have formed stars as recently as 30-70 Myr ago; long after the interactions that created the HI arm. This object is about 1 kpc in extent, and is considered a tidal dwarf (TD) candidate. To better characterize its star forming environment, we place limits on the molecular gas and dust content of this potential TD object, and compare its properties to well-studied star forming regions. The infrared observations were obtained as part of the Spitzer Space Telescope Research Program for Teachers and Students, so these data are also being used for educational purposes by teachers and students across the US.
