This download is a PowerPoint and lesson plan explaining Doppler Effect of waves due to moving sources. This is linked to astronomy and the calculation of galactic distances due to the correlation with the Hubble constant.
There is a detailed explanation of the Audacity software (copyright free and available from the internet) which is included as a ZIP file for use in performing an experiment.
This is lesson 10 / 12 from my Astrophysics / Cosmology course, all available individually or as a bundle at a reduced price.
