Students build a three-dimensional model of the rotation of the earth to appreciate the extremes of daylight hours at different months of the year, and make connections between available sunlight and the growth and behavior of plants of the arctic.

Learning Objectives
Students will be able to:
✔ Demonstrate how the tilt of the earth and its rotation affects day length in the arctic (and seasons around the world).
✔ Explain how day length and available solar radiation influence survival strategies of plants native to the arctic.
