This video 4:45 video segment, of Bill Nye the Science Guy's full video call Bill Nye the Science Guy: Earth's Season's, explains why earth has seasons. Bill begins by activating students' prior knowledge about the seasons. Then he uncovers the misconception that seasons change due to how close or far away earth is from the sun. He explains how the Earth's tilt and the sun's light angle are responsible for Winter, Spring, Summer, and Fall. His illustrations in the Consider the Following section of the video provide a fuller understanding of the reason for the seasons and more importantly for this 1st grade Disciplinary Core Idea, the amount of Sunlight in the summer as compared to the winter is different.
