32 Shades of Water
What does the color of the water tell you about conditions in marine and freshwater environments? What are the variables that affect that color? In this lesson students will participate in a variety of activities that allows them to brainstorm what impacts the color of our global water. They will perform research, analyze graphs and use real time data sets to make predictions, discuss limitations of methodology and the similarities and differences between different parts of the global ocean system.
