About This Product
Teachers position the Sun reference so one side of the Earth model is lit, then turn the model slowly so students can follow a location moving from daylight into darkness. It supports astronomy, geography and environmental science lessons on Earth rotation, sunlight and shadow, and can lead into discussion of time zones and seasons.
