This challenging activity involves the interpretation of data and then using it to make predictions for the red-shift of galaxies. It gives an opportunity to practice a range of maths skills such as converting units, significant figures, rearranging equations and graph drawing. 

Example questions

  1. Convert the value of the red-shift for a speed of 300 km/s into Hz
  2. Draw a graph of the results in the table.
  3. Describe the trend between the speed at which the galaxy is moving away from Earth and the red-shift observed.
