About This Lesson
This handout gives students Hubble's original 1929 data on the distance and velocities of a range of galaxies. students are given axis and must plot distance against time and draw a conclusion from the data (Hubble’s law).V = Ho x D Velocity = (1/Time) x Distance.Good for getting students to plot graphs and find relationships. Most able students can be given graph paper and asked about strong/weak correlation.Good for calculating gradient and deriving Hubble’s constant (about 500 km/s/MPc for this 1929 data). Most able can find Hubble time (T=1/Ho) as the age of the universe.
Great resource and well structured. Thank you.
