you could, for example, say something along the lines of:
"media utilizes a wide variety of techniques, from layouts to images to sounds and video. one way they could work together, would be by creating a website beneficial to a certain cause. for this example we could use world hunger, for the website you'd have to incorporate a layout. you'd also need images to persuade the viewers and potential benefactors. you could use sound and video by having either a presentation or links to documentations about world hunger or your chosen cause."
hope this is what you were looking for !
