Losing Blue
What does it mean to lose a colour? Losing Blue is a cinematic poem that delves into the impending loss of some of the most extraordinary blues on Earth—the otherworldly blues of ancient mountain lakes. Glacier-fed alpine lakes each have a unique blue formed by the mountains and ice that shaped them. These intense colours hold the memory of “deep time,” geological processes millions of years old. Now climate change is rapidly accelerating environmental shifts and causing some of these spectacular blues to vanish.

Write a 'blue' profile: Learners investigate the rare phenomenon of the colour blue in nature. They begin by learning how human eyes perceive colour, then research a naturally occurring blue object—biotic or abiotic. Students write a "blue profile" by explaining what makes their chosen item appear blue, and present their findings to peers. Finally, they reflect on how the world would change if that blue item were lost
