This NASA visualization shows sea surface salinity observations (September 2011-September 2014). Students review the video and answer questions.

Compare a histogram and map to determine the differences in the information conveyed in each data display.

In this activity, students will use sea-level rise data to create models and compare short-term trends to long-term trends. They will then determine whether sea-level rise is occurring based on the data.

What is sea-level rise and how does it affect us? This "Teachable Moment" looks at the science behind sea-level rise and offers lessons and tools for teaching students about this important climate topic.
