Produced by the Institute of Physics, in this learning episode, students look at the expanding universe by examining galaxies, Hubble's observations and cosmological red shift. A simple activity allows students to model Hubble's law.
Through discussion and activities, students look at:
* observing a galaxy
* the scale of the Universe
* Hubble’s observations
* demonstrating the expanding universe
* modelling Hubble’s law
* cosmological red shift
* red shift of quasars
