Positives

• This resource effectively outlines the ecological implications of a changing climate.
  
• The video describes the concepts of competition, energy transfer, food web dynamics, and invasive species in a well-illustrated example.

Additional Prerequisites

• Students should be familiar with the concepts of food webs and energy transfer between trophic levels.
• There may be an ad before the video.
  

Differentiation

• Before showing the video, ask students to predict a typical food chain in an Arctic ecosystem.  Ask them about characteristics of cold water animal species.
• Consider having students draw a graphic organizer to compare and contrast Atlantic and Arctic aquatic food chains.
• Discuss other regions where animal migrations due to climate change may have ecological impacts on native species.
• Climate Confusion and Arctic Animals' Movement Patterns are Shifting in Different Ways as the Climate Changes are recommended resources for further exploration.
