This is a unit in 6 sessions about the seasons on earth. Learners will investigate the reason for seasons on earth. They will look at the circular orbit of earth, year-long temperature and daylight hours across different latitudes, compare models of the earth with and without tilt, investigate angle and intensity of sunlight, and ends with a discussion to solidify their understanding of the reason for seasons. It supports the process of modeling to determine an answer to a question. This is Unit 2 of the GEMS Space Science Sequence for Grades 6-8, which is available for purchase (see related link).
