Aimed at pupils aged 14-18, this activity focuses on the concept of Universal expansion and the correlation between the distance and redshift of galaxies discovered by astronomer Edwin Hubble. Students will analyse real data from a set of galaxies to calculate Hubble's Constant; how fast the Universe is expanding. This activity is also a great opportunity to practice and learn valuable Excel skills and spreadsheet manipulation.
