Biology In Elementary Schools is a Saint Michael's College student project from a course that ran between 2007 and 2010 and fully described in this book chapter.

This can be a simple graphing activity. You could also choose to use the data for linear regression. I have posted photographs of a yard stick taken at regular intervals during the February 14 2007 snowstorm in South Burlington Vermont. The times are given under each photograph, and snow accumulation can be recorded by zooming in (single click) on the photographs.
Suggestion progression of activity (stop at level appropriate for your grade):
- Make data table recording time and snow depth.
- Convert to metric units perhaps.
- Line graph of data set.
- Measure slope to measure rate of snow accumulation (express in inches per hour; or per minute).
- Run a linear regression to determine if a significant relationship exists between time and snow accumulation.
Valentine's Day storm
Saint Patrick's Day storm
During this storm, the meter stick was in a pile of old snow that measured about 40 cm wide. Snow tended not to accumulate as rapidly because of the small surface size.

Upload a series of photos from your favorite storm! Comparative graphs might be interesting.
