Activity (Hands-On)Grades 3 - 5
Snow vs. Water
Students explore snowmelt as a source of fresh water that used in many communities. Students determine whether they think one cup of snow produces an equal amount of water. They use a model to explain how packed snow does not yield the same amount in fresh water.
Figure 1. A glacier in Peru and the river created from the glacial melt.
Engineers work in many fields associated with precipitation. Engineers study glaciers to better understand their dates of formation and current demise. They deal with issues of pollution transport and water yield. Engineers also monitor reservoirs and dams to prevent flooding.
After this activity, students should be able to:
- Describe snowmelt as a source of fresh water, used in many communities.
- Use a model to explain how packed snow does not yield the same amount in fresh water.
- Describe how environmental engineers can use knowledge about snowmelt to design water treatment plants.
