Modeling the Reasons for Seasonal Change DLESE Reviewed Collection
The purpose of this resource is to understand what causes the Earth's seasons with a focus on the Earth's tilt and spherical shape. Students learn how sunlight spreads over the Earth at different times of the year, emphasizing the solstices and the equinoxes. Students investigate the effect of the Earth.s tilt on the spread of sunlight by modeling different tilts using a three-dimensional polyhedron which they construct from paper. Students calculate the relative sunlight intensity received by the Northern and Southern Hemispheres to understand seasonal differences between the hemispheres.
