How does a screen print work? What is the thing (no matter what it is made from) called that makes it so that there is an image on the screen? It's a general word that is not related to any one specific media or method.

Your question is not entirely clear, but perhaps my answer will help you sort out what you need to know.
A screen of fine wire mesh is set in an aluminum or wooden frame. Emulsion that will later be exposed to ultraviolet light is spread over the screen mesh. The film positive is pressed onto the mesh and exposed to the ultraviolet light, which hardens the emulsion correlated to the negative image while leaving the rest of the emulsion soft. The soft emulsion is washed away with jet water washing. A rubber blade called a "squeegee" presses the medium through the open spaces of the screen mesh, the spaces where the emulsion was washed away, and is pulled back to its starting place. This back-and-forth squeegee action produces the print, which is now made.
- film positive
- ultraviolet light exposure
