Description and Comments

More on the Activity: GLAST, the Gamma-ray Large Area Space Telescope is one of the satellites in NASA’s Structure and Evolution of the Universe theme. GLAST detects gamma rays, the highest energy light in the electromagnetic spectrum. Gamma-ray sources include black holes, pulsars, supernova remnants, and active galaxies. Active galaxies are distant galaxies with supermassive black holes at their cores. This presentation will include an informational PowerPoint presentation on the satellite itself and the science of black holes and gamma-rays. Participants will then do a series of hands-on activities that include building a model of an active galaxy and using small angle approximation to measure the angular size of a human and the angular size of a galaxy.

More on the Discussion: Everyone will be invited to share the good ideas that work for them in their classrooms. Maybe it is a particular piece of software that works so great for you, or a lesson you have just perfected. Perhaps you have figured out how to use the assessment data you are given to support learning. We all have things we do that others can benefit from, this discussion will provide the forum to do that. Bring your good ideas!
