We propose to use IRAC and MIPS 70 micron band, together with SDSS and Palomar spectra, to obtain the spectral energy distribution (SED) of a sample of blue compact dwarf galaxies (BCD), which may be local laboratories for the study of star formation in the early universe. Unlike normal starburst galaxies, which have strong PAH bands, low-ionization emission lines and a continuum peaking near 80 micron, the third-metal poor BCD, SBS0335-052E, shows no evidence of PAH emission and a very flat mid-IR continuum peaking ~30 micron. Is this dramatical difference common among typical BCDs and starburst galaxies? What is the underlying physics? If the spectra of BCDs do peak at a much shorter wavelength, it would be very important for us to have mid-IR flux densities shortward of 30 micron in order to better constrain the SEDs. The new IRAC and MIPS data, together with 16 and 22 micron flux densitities obtained from our GTO program and available optical spectra, will allow us to better understand the SEDs of these BCDs. Faint as they are, the unprecedented sensitivity of Spitzer Space Telescope will provides us a unique tool to complete this study and an insight into the galaxy evolution in the most primodial-like environment.
