Students journey into space to create and experience the cycles, systems and relationships between the earth, moon and sun using our huge, inflatable Earth model and scale-sized moon. While interacting with the inflatable representations in a darkened gymnasium with a light to represent the sun, students manipulate the models to experience eclipses, seasonal/lunar cycles, creation of winds, day/night cycles, tides, rotation vs revolution, physical characteristics of the earth, moon and sun, gravity, order of the planets, seasons and more! The Orbit Earth Expo Program correlates to the state and grade level science objectives. There are different age-appropriate programs for each grade level.
