This worksheet gives pupils Hubble's original 1929 data on the distance and velocities of a range of galaxies. Pupils are given axis and must plot distance against time a draw a conclusion from the data (Hubble’s law).
V = Ho x D Velocity = (1/Time) x Distance.
KS4: Good for getting pupils to plot graphs and find relationships. Most able pupils can be given graph paper and asked about strong/weak correlation.
KS5: 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, very useful for students.
Thank you for the resource. Great to accompany the cosmology unit.
This is a great resource. It works very well, however the gradient is difficult to establish since the graph is not graph paper grid. I modified it to have graphical grid by adding major and minor vertical grid lines. Works a treat, thanks for sharing.
