Investigation 4: Supernova Remnants

Overview: This investigation gives students further chance to practice many of the skills and observations they've already learned to make, but introduces the idea of discrete spectra that are formed by electron transitions in atoms of particular elements. Students get to investigate the properties of one supernova remnant together as a group, and then gather information about one of 3 other supernova remnants, finally sharing their results in a mini poster session which leads to the collaborative development of possible research questions/topics.
