Notes on other good resources that I can't include here because they're copywrighted.
All graphs and (most) pictures are created as shapes in MS Word, so their quality does not degrade when printed.
Note: Parts of the unit refer to the ESRT. This is New York State's Earth Science Reference Tables. Even if you don't teach in New York State, they are a fantastic resource (both of information and to help students practice looking up information elsewhere, which they will often do in the real world). Printable copies can be found here or here.
