How does a Light Bulb Work?

This website shows a video on how a light bulb works. In this film, students are shown illustrations and models with captions on what the display is showing, as well as steps of the process of how a light bulb produces light. This video is for students aged 9-13, but I think that this video is great for anyone older who is interested on how a light bulb works because it is very informative.
