Alaska SeaGrant, Alaska Seas and Rivers Curriculum

This activity engages learners in exploring the impact of climate change on arctic sea ice in the Bering Sea. They graph and analyze sea ice extent data, conduct a lab on thermal expansion of water, and then observe how a scientist collects long-term data on a bird population.

Activity takes five to six class periods. Video streaming capability is necessary.

Climate Literacy
About Teaching Climate Literacy

Humans can adapt to climate change by reducing their vulnerability to its impacts. Actions such as moving to higher ground to avoid rising sea levels, planting new crops that will thrive under new climate conditions, or using new building technologies represent adaptation strategies. Adaptation often requires financial investment in new or enhanced research, technology, and infrastructure.
About Teaching the Guiding Principle
Other materials addressing GPf
Sunlight reaching the Earth can heat the land, ocean, and atmosphere. Some of that sunlight is reflected back to space by the surface, clouds, or ice. Much of the sunlight that reaches Earth is absorbed and warms the planet.
About Teaching Principle 1
Other materials addressing 1a
Melting of ice sheets and glaciers, combined with the thermal expansion of seawater as the oceans warm, is causing sea level to rise. Seawater is beginning to move onto low-lying land and to contaminate coastal fresh water sources and beginning to submerge coastal facilities and barrier islands. Sea-level rise increases the risk of damage to homes and buildings from storm surges such as those that accompany hurricanes.
About Teaching Principle 7
Other materials addressing 7a
Ecosystems on land and in the ocean have been and will continue to be disturbed by climate change. Animals, plants, bacteria, and viruses will migrate to new areas with favorable climate conditions. Infectious diseases and certain species will be able to invade areas that they did not previously inhabit.

Benchmarks for Science Literacy

Light and other electromagnetic waves can warm objects. How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed.

Teaching Tips

  • There is an easy link to a very comprehensive teacher background section. In the NSIDC sea ice index visual, teachers should make sure that students can read and understand the bits of critical information at the top of each visual and that the right-hand visual represents a baseline at the beginning of collecting time.
  • NSIDC sea ice index is updated here: http://nsidc.org/data/seaice_index/
  • Also, Arctic Sea ice is tracked daily here at NSIDC: http://nsidc.org/arcticseaicenews/

About the Science

  • The sea ice activity is the first of five investigations in which which students explore different impacts of climate change on arctic sea ice and the Bering Sea.
  • After they graph and analyze sea ice extent data, students explore thermal expansion of water as a lab and then observe how a scientist collects long-term data on a bird population.
  • Comments from expert scientist:The lesson demonstrates how Arctic sea ice is changing and helps students understand how those changes may impact climate, wildlife, and human activities.
  • It would be good to add mention of another part of the world's ice whose melt does affect sea level - namely land ice - the ice sheets and glaciers, and it could be demonstrated by dropping ice cubes into the water.

About the Pedagogy

  • Teachers should consider all of the investigations in this unit on Arctic Sea Ice. There is a lot of flexibility built into this series of investigations.
  • Teachers can use specific investigations or the entire set. Additionally there are multiple resources to choose from.
  • The teacher background section is very comprehensive.

Technical Details/Ease of Use

  • Capacity of available computers to stream videos may be a concern for some schools.
