Concord Consortium has a terrific site to use when teaching fifth grade science standards related to water quality and testing.
These links will support that study including understanding of the watershed.

- Recommended water testing kit: http://www.flinnsci.com/store/scripts/prodView.asp?idProduct=15456
There are five activities that you are able to customize on their website. Once you sign in as a teacher, you may include your students. The site meets privacy issues. All work goes to reports for the teacher.
