Graphing Water on Earth

Shared by: Liz

What is this task about? 

Students describe and generate charts to answer a scientific question on differences in volume between fresh water and salt water.

Students consider why a given graph, while accurate, does not provide the information needed to answer a specific question about the distribution fresh and salt water on Earth. They then create their own graph and describe why it is better for answering the question than the original graph. 

The three dimensions of this task are
  • DCI: ESS2.C: The roles of water in Earth’s surface processes
  • SEP: Using Mathematics and Computational Thinking
  • CCC: Scale, Proportion, and Quantity
