From days of 24 hour sunlight, to endless nights that last for days, the Arctic is a very unique place to live. Examine the seasonal changes that occur in the northern-most reaches of the globe and the impact they have on the plants and animals living there. The included worksheet offers a number of different opportunities for learners to demonstrate their understanding of this unique region. This lesson would fit nicely in either a unit on ecosystems or weather and climate in an upper-elementary science class.
