We propose for 24.2 hrs of deep MIPS scan observations of five isolated, irregular dwarf galaxies to determine the distribution, mass, and extent of both the warm (T~60K) and cold (T~15K) dust components. Dwarfs are considered to be the building blocks of which all more luminous systems are formed, yet are the least studied with regards to dust and metal retention due to their faint nature in the infrared. Discovering if or where significant amounts of dust and, by proxy, metals, are located in dwarfs will place much needed constraints on chemical evolution models of these systems. Furthermore, the observations will address questions that are crucial for understanding galaxy evolution in more general terms, such as how galaxies typically form, retain, and/or accumulate dust and metals, and in what quantities and temperatures, how dust is heated by other galactic components, how dust emission is correlated with other cold extended material such as the H I emission, and how galactic dust typically interacts with its surrounding environment. Quiescent dwarfs simply must be observed deeply with Spitzer if we are to understand galaxy evolution with a view unbiased by optical luminosity.
