In this activity, students read Henrietta Leavitt’s paper comparing the brightness and period of stars. Students learn about the relationship between the period and luminosity of variable stars while experiencing how scientists really collect data by preparing graphs and comparing their data to Leavitt’s. This can be used with Cosmic Times 1929 or alone.
