The Doppler Effect
Now this is a very good demonstration of the Doppler Effect and how it works. A police car with its siren blazing is filmed as it travels closer and then farther away. The effect is explained through text and an illustration. Good video.
Khan Academy
Red Shift, Scale of the Universe, Cosmology and Astronomy
The Red Shift concept can be one of the most confusing in physics. Learners may find it helpful to start with learning more about the Doppler Effect before introducing this video.
