Reflection: Real World Applications How Does Saltwater Differ From Freshwater? - Section 2: Engage

 

Incorporating Geography into Science

In this lesson, I incorporate maps as part of students’ inquiry on saltwater and freshwater. I provide them atlas' and ask them to locate examples of each kind. I give them this task because I want them to recognize that Earth has many examples of freshwaters and fewer examples of salt waters, but that amount of saltwater on Earth is much greater than freshwater. It's a chance for them to visually distinguish between bodies of waters and find their relationships with Earth's hydrosphere system. Having them use maps for this task helps them make this connection and develop an understanding and awareness about the kinds of waters on Earth. 

Maps are an effective way of helping students develop an awareness of places and things on Earth. It is important for them to recognize that maps provide relevant information about Earth’s features including land, water, and distributions.
