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.

I loved that the graph was already set up with good scaling, that the data was the ACTUAL data from Edwin Hubble. <br /> <br /> I thought it was redundant that the answers to the questions on the second page were essentially given on the bottom of the page in the concept check.<br /> <br /> I think it could be improved by adding a line of best fit and asking students to extrapolate data-- ask them about what they would expect a point on the graph to be (for a certain speed or distance). Also, on the front it says speed, and the back it uses the term velocity.<br /> <br /> I added an explanation of what a mega-parsec was and what km/s meant, as my 6th graders have not necessarily been exposed to this.
