Preset the cylinder on the first day of a season and see if the students can determine the season by the position of the Big Dipper. Have the students find the given seasonal constellation for that season. Turn down the projector. Turn up the side lamps. Have students carefully exit the StarLab.
Students are to keep a dipper finder for future observations.
Jay M. Pasachoff, Contemporary Astronomy, 3rd ed. CBS College Publishing, 1981. While in the StarLab, go through all the seasonal positions of the Big Dipper again on the Urban Starfield Cylinder. Allow students time to pick out the six circumpolar constellations along with a seasonal constellation for a total of ten constellations. Before exiting the StarLab, position the cylinder to the day of instruction.
