Interactive computer-based simulations, 'serious' games, and virtual labs are being developed and used with growing frequency in a range of education disciplines at all age levels. These resources are employed across formal education, informal education, and educational outreach settings. This poster will present a web-based compendium of games and simulations from various sources which span the STEM (Science, Technology, Engineering and Mathematics) content disciplines. Although there are several good online collections of such resources focused on specific topics (e.g. astronomy education) or from specific sources (e.g. NOAA's games web site), we believe this web site is the first to present such a collection spanning the gamut of sources and STEM content disciplines.
