In this inquiry investigation, students study the motion and positions of the Earth and how they affect the path of sunlight we get in different places. They discover that the Earth must be curved to account for the different lengths of shadows at different latitudes and that the Sun is very far away. Supplies required include globes, blue-tak, toothpick, flashlights, and golf tees. This is the seventh of 10 inquiry investigations in Threads of Inquiry: Observing the World Around Us. Each lesson includes teacher background information, a narrative that models and describes the inquiry process applied in the lesson, and a hands-on inquiry investigation. Literacy extensions and a non-linguistic pre- and post-assessment are also included.
