Density

• Definition Density is mass per unit volume
• D M / V
• Mass (g)
• Volume (cm3)
• Density (g/cm3)

To find volume (tube) (p r2) h h snow
depth r radius p pi (3.14)

• Adaptation to this activity
• Leave tray out for 24 hours and re-calculate
  density
• Add water to 1 or 2 trays for more variations of
  density
