The Vatican site provides the link bellow to access the Sistine Chapel with superb visual resolution. This is a great resource for art history teachers and students, and obviously provides a much more interactive and memorable experience than looking at a dozen slides, enjoy:

Students explore the site and choose one image/figure for a sketchbook assignment. Students choose any piece and research its meaning and complete a sketch using coloured pencils. Students must also come up with one puzzle or question about their chosen piece.
