Measuring the Age of the Universe

This Measuring the Age of the Universe activity & project also includes:

Just when is the universe's birthdate? Pupils use previously collected spectra data to find the redshift and radial velocity of supernovas. They then calculate the distance before finally creating a Hubble diagram. Finally, individuals use their models and information to calculate a Hubble constant, ultimately determining the age of the universe.
