So how does a lightbulb work? Light is a form of energy produced by tiny atoms. The energy is called photons. Photons are produced when atoms "get excited" and start moving. Heat will do this. When heat is added to something it causes the atoms to jump around and move. This will produce photons. In the average lightbulb there is a filament. Usually there is about six feet of metal filament in a bulb. This filament is just an electricity conductor. When the electricity is added it makes heat which makes the atoms around the filament move creating light!
