This lab activity will introduce students to snow, ice and water properties that they will apply to a local snow study, and later to understanding glaciers.
To understand the basics of water, ice, and snow density and composition.
What are the properties of snow, ice, and water?
Later application: How have glaciers shaped our local terrain?
snow, ice, water, pan balance, graduated cylinder
Introduce snow, ice, and water to students. Have students list similarities and differences of the
substances as an opening journal. Share responses.
Instruct students that today they will use Excel on a computer to create a data table of snow, ice, and water densities.
They will use a balance to mass and calculate grams.
They will use a graduated cylinder to calculate volume.
SAFETY: Be careful when using glass. DO NOT USE the glass graduated cylinder to scoop ice or snow, the cylinder may break. Also, always keep glass and materials an full hands length from the side of any table.
Follow the data collection sheet to collect data and reflect on interpretation of the data.
Review student data collection. Check calculations.
Answer Key or Rubric:
Answers are based on calculations of density.
Benchmark or Standards:
Glaciers are large bodies of ice that move under the influence of gravity. They form part of both the rock and water cycles. Glaciers and ice sheets have shaped the landscape of the Great Lakes region. Areas that have been occupied by ice sheets are depressed. When the ice sheet is removed, the region rebounds (see also climate change). (prerequisite)
