Climate Change and Arctic Ecosystems
http://climate.agry.purdue.edu/climate/ccc/Files/cc_arctic.pdf

Project Activities for Conceptualizing Climate and Climate Change, Purdue University

In this activity, students learn about how climate change is affecting the Arctic ecosystem and then investigate how this change is impacting polar bear populations. Students analyze maps of Arctic sea ice, temperature graphs, and polar bear population data to answer questions about the impact of climate change on the Arctic ecosystem.

Activity will take about two 45-minute class periods.

Climate Literacy
About Teaching Climate Literacy

Individual organisms survive within specific ranges of temperature, precipitation, humidity, and sunlight. Organisms exposed to climate conditions outside their normal range must adapt or migrate, or they will perish.
About Teaching Principle 3
Other materials addressing 3a
Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species. The distribution patterns of fossils show evidence of gradual as well as abrupt extinctions related to climate change in the past.

The world contains a wide diversity of physical conditions, which creates a wide variety of environments: freshwater, marine, forest, desert, grassland, mountain, and others. In any particular environment, the growth and survival of organisms depend on the physical conditions

Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Questions at the beginning seem odd in their placement, but could be used as a pre-test.
  • Educator should enlarge and laminate the map of the Arctic for use in the activity to improve readability.
  • Educators should project the given images and go through the process of calculating percentage of sea ice cover with students.

About the Science

  • Good background readings for students are provided.
  • Activity is very current and has scientifically-rich resources.
  • In preparation for this lesson, educators should make sure they understand the difference between temperature anomalies or change in temperature from some mean temperature - usually a 30-year average.
  • Comment from scientist: Some of the numbers on the web page are somewhat outdated. Educator should check for most up-to-date numbers on: http://pbsg.npolar.no/en/.
  • Comment from scientist: Page 3 states that the central part of the Arctic is frozen all year - this is no longer true.
  • Comment from scientist: All materials on this site imply that climate change is the only factor potentially responsible for the decline of the species. The major threats are: climate change, over-harvest, pollution, oil development, and tourism (not listed in order of priority).

About the Pedagogy

  • This is a best practice lesson in its layout format, which takes the learner from engaging their thinking and making predictions, to exploring and explaining concepts, to extending their thinking, and finally to applying knowledge and reflecting.
  • Group work and discussions are good strategies for students of different learning styles.
  • Scaffolding of concepts is appropriate for the lesson and promotes the learning.
  • The lesson ends with a good performance assessment (concept mapping) to evaluate student understanding.
  • Links to a PowerPoint and concept map are included in the Teaching Tips section.

Technical Details/Ease of Use

  • The activity is nicely organized and has an attractive format that will engage students.
  • The educator must open separate windows for educator guide, concept map and PowerPoint slides at http://iclimate.org/ccc.
