I uploaded my beginning of the year parent letter into google docs (clothing responsibilities portion only) and shared it with several MDE colleagues. I can see using this with other HF colleagues since they are always asking me what I send home for "this" or "that" so now they can go to google docs and see. What is cool is they can change the page to fit their needs.
As a HF teacher, it might be hard google docs but the form would be good to use to get information about field days, fitnessgram or square dancing.
Haven't found any google apps that I can use with students but will try. In my classroom, TEA suggests the students experience moderate to vigorous physical activity 80% of their class time. Therefore, it would be hard to use but I am open to suggestions. Perhaps my colleagues will share something in google docs with me. :-)
