Google Sites helps anyone create clean, functional, responsive websites on any topic. The drag-and-drop editor is easy to use, but there's little design inspiration built in. To start using Google Sites, students log in, click on the rainbow "+" button, and dive right into the design. There's a very brief tour of the interface, and then students are given a mostly blank page with a place to add their site's name and the main page's name. The site's name will become students' default URL once they publish unless they change it.
