"Mindy's Ice Rink": Mindy is impatient for winter, because she wants to ice skate. So Jet, Sean, Sydney, and Celery fly to Saturn's icy rings to gather ice from them and return to build a Saturn-ringed skating rink around Jet's house. "Measure for Measure": Jet, Sydney, Sean, Mindy, and Sunspot decide to make a scaled replica of the solar system using found items in their own neighborhood and in doing so learn that an Astronomical Unit is the distance from the Earth to the Sun.
