This is a project project sheet with a rubric, and a page of some information about the project. It includes a one page research sheet with questions for students about the history of stained glass. It also includes a link to a tutorial. If you have overhead transparencies this works well, or you can also use glass from picture frames.
Timeline for this project is approx 2-4 classes.
It's a good intro to painting assignment, and can be good for teaching colour theory and mixing colours.
I have done this with grade 9 students, but it would work for junior high as well as high school.
