In this integrated math and science activity, students build models to examine the relationships between the types and percentages of water distributed on Earth.
What we want the students to see is that there is proportionally very little potable water on Earth, and we should avoid polluting or wasting it.
This activity supports the primary PE of
5-ESS2-2 Students who demonstrate understanding can: Describe and graph the amounts and percentages of water and fresh water in various reservoirs to provide evidence about the distribution of water on Earth.
With the secondary PE of
5-ESS3-1 Students who demonstrate understanding can: Obtain and combine information about ways individual communities use science ideas to protect the Earth’s resources and environment.
