Days 165-166: Hubble’s Law Lab

The juniors in AP Physics 2 spent two days working through a fantastic Hubble’s Law lab from the University of Washington. I’ve explored a lot of Hubble’s Law labs, and this one is my favorite. It is the most authentic because students use actual images to calculate the distance to the galaxies and spectrum data to calculate the relative velocities.
