The ICESat-2 (Ice, Cloud and land Elevation Satellite) mission is designed to measure the depth of Earths sea ice, glaciers and ice sheets. The satellite will carry a single photon counting altimeter called the ATLAS (Advanced Topographic Laser Altimeter System).
Why does Sea Ice Melt Matter?
Engaging Students in STEM Real World problem Solving.
As an educator, I see one of my most important challenges is to engage students in real world problem solving. If you want to get them engaged in their learning ask them to find credible solutions to a problem that has societal and future implications. There are criteria for successful PBL (Problem Based Learning Lesson).
- The problem must impact people’s lives. There must be compelling data and evidence to argue for the solution.
- Students must be able to relate to the issue. Build the context by using their own life experiences, videos and images.
- Students must have access to the resources to explore the problem and their solutions.
- It should align with the standards. What do you want them to learn?
Students might see climate change and sea ice loss as a future threat. Something they do not have to worry about now. NASA’s educational resources will help you to engage them in the real measurable consequences of climate change. Let’s look at 5 reasons why arctic sea ice matters and some resources for educators and students to use to explore the reasons.
- It Reflects Light
- It affects ocean current patterns and circulation
- It contains frozen deposits of methane which if released increases greenhouse gas problems.
- It supports Native People
- It supports native wildlife:
Sea ice is white which reflects most of the sunlight back to space. In its absence, the ocean gets warmer. As the ocean waters get warmer, they melt more ice, causing a loop.

This drives weather patterns. The sinking and floating of the different temperatures and salinity of the water impact the change.
