Students Assemble Their Own Models to View the Changing Relationship of Sun to Earth

Why are summer days longer than winter days? When will the sun rise and set on different days of the year? How long is each day of the year? Students will be able to answer these questions for themselves when they construct their own models. Made of heavy paper, the models can be positioned to show their relation to one another at any given time of the year. You will receive enough materials for 24 models. Size: 4" dia.
