The lesson includes links to handouts, procedures, and introductory mash-up videos. (View Less)

Using three images from the Wide-field Infrared Survey Explorer (WISE) mission, students measure and analyze infrared light from objects to identify Brown Dwarfs and Ultra-Luminous Infrared Galaxies (ULIRGs). The lesson includes a teacher’s guide,... (View More) student worksheet and PowerPoint presentation (which contains the three images to be analyzed). (View Less)

Dieter Hartmann, a high-energy physicist, presents a story-based lesson on the science of Gamma-Ray astronomy. The lesson focuses on gamma-ray bursts; examining their sources, types, and links to the origin and evolution of the Universe. The...
