Sea Level Rise By Decade: Student Activity
For over 20 years, satellite instruments have measured the sea surface height of our ever-changing oceans. This video of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.
For over 20 years, satellite instruments have measured the sea surface height of our ever-changing oceans. This line plot and video show the patterns of rising and falling ocean levels across the globe from the 1990's to the 2010's.
Part A: Observe Patterns in a Line Plot
- In the graph below, what is the unit of measure for sea surface height?
- What is the general trend for sea surface height over the 20 years?
- What years do you see the biggest range (the difference between high and low values) of sea surface height?
Part B: Observing Data Values in an Animation
- Watch the video below once to observe the general patterns you saw on the line plot.
- Analyze the color bar below. What do the blue areas represent, in general? White areas? Yellow to red areas?
- Re-watch the animation, paying attention to the years that you identified as having the greatest range of sea surface height in Part A. Where on the map do you observe those changes?
- Imagine that you are a journalist writing for a newspaper, covering a story about sea-level change. Write your own headline that describes the patterns you noticed in the line plot and the animation.
Teachers, these mini lessons/student activities are perfect "warm up" tasks that can be used as a hook, bell ringer, exit slip, etc. They take less than a class period to complete. Learn more on the "My NASA Data What are Mini Lessons?" page.
