In these activities and story book, students wonder why hummingbirds have stopped visiting their school. They learn about the needs of the hummingbirds, the seasonal changes where they live, and the environment where the hummingbirds spend the winter. Students describe the seasonal changes in a local habitat, observe how colors in nature change through the seasons, and research hummingbirds.

Students analyze and interpret graphs to compare the flow of shortwave energy from the Sun toward China over the course of a year on cloudy versus clear days.
