Exploring Hubble Constant Data in an Introductory Course

Popular accounts of exciting discoveries often draw students to physics and astronomy, but at the introductory level it is challenging connect with these in a meaningful way. The use real astronomical data classroom can help bridge this gap build valuable quantitative scientific reasoning skills. This paper presents strategy for studying Hubble's Law accelerating expansion universe using actual data. Along understanding physical concepts, an explicit goal develop skills analyzing terms model.
