Course Material 2A: Day & Night, Sunrise & Sunset
Students begin building an Earth-Moon-Sun (EMS) model by determining what bodies and which of their motions interact to cause day and night. They then elaborate on the model and determine how it relates to sunrise and sunset. Students use props such as globes and light sources to represent the Earth and Sun while they demonstrate how the Earths rotation results in day/night and sunrise/sunset phenomena.
Successful completion involves
Students will complete a Phenomena/Objects/Motions (POM) chart that answers the question "Why do we experience Day and Night?" They will include the phenomena observed, the objects and motions involved, a written explanation, and a diagram of their model. They will also do the same for the question "Why does the Sun rise in the east and set in the west?"
