Positives

• The scrolling format of this article with quotes, videos, and images is unique and an effective way to tell an ecological story with many interconnected parts.
• The images and videos of the Greenland ice sheet and whales are beautiful and captivating, inspiring awe in the viewer.
• The interactive article shows a video of scientists using fluorescent dye to track how Greenland's ice melt is moving below the ice sheet's surface and into the ocean, demonstrating scientific methods for investigating a phenomenon.
• The diagrams and data relating to changing and warming ocean currents provide excellent visuals and evidence for understanding the consequences of a warming and changing ocean.

Additional Prerequisites

• Learners should be familiar with ocean currents and the difference between global freshwater and saltwater sources.
• It may benefit learners to understand the causes behind glacial melting and ocean warming.

Differentiation

• Before viewing the resource, ask students how the shifting range of the right whale's plankton food source might affect the whales and prompt them to consider human water use if they don't do so independently.
• Consider having students work in pairs to read the story first and jot down their thoughts and questions about the environmental phenomena.
• Create a graphic organizer to help students record the science behind the ecological issue of right whales and consider including a global map to help them diagram information about the changing ocean currents and shifting organism ranges. 
• To conclude a lesson using this resource, ask students to describe how they think the unique format of the story impacted their interest and prompt them to consider how they could use this type of storytelling for topics they care about.
• As an extension, have students complete the ice melt quiz linked at the bottom of the story to dive deeper into the causes and effects of global ice melt.
