I really like the simplicity of the activity introduced here explaining how day and night occur. After asking groups to discuss how they believe or what they know about how day and night occur I would use the flashlight activity introduced here to explain in a simple what is happening. I would give each child a small ball and ask them to draw a person or house on their ball they would be able to try the activity themselves and to explore when their figure is experiencing day or night. I would finish by asking each child to draw a picture of their neighbourhood at night or during the day, showing us where the sun or moon is in the sky.
I think a great activity to support this in art class would be asking a group to create their own model to explain how day and night happens to younger children and asking them to visit our infant classes to show what they have learned and use their model to teach.
