Each of the SnowSchool programs is posted on the site with contact information. One of the activities on the site introduces students to the idea that snow samples from different locations and conditions have different densities. The students use buckets to collect surface snow, snow deep beneath the surface, and newly fallen snow. They allow the snow to melt in the buckets and measure its volume. This process is repeated ten times and the data are recorded on the data sheet provided on the site.
Students use the site's handout to learn about charting their data.
The activity also offers a printable quiz that covers the concepts related to snow density as well as graphing techniques.
