In the activity, students use “point-source” light, light meters, and graphing software to quantify reduction in light over distance. Students calculate distances between light sources and light meters at random placements to model how distances to Cepheid variable stars are measured. This activity accompanies the Cosmic Times 1929 Home Edition and Late Edition.
