Horizon

Representations of a problem-based lesson in which students investigate how far away the horizon appears when standing on a sandbar in the middle of the ocean. Using visualization and physical exploration of this natural setting, students pose questions and draw mathematical conclusions, applying the Pythagorean theorem to find unknown side lengths in right triangles and developing an understanding of circle properties such as radius and tangent lines.
