A Human Orrery

Authors

A 3-Dimensional Kinesthetic Model of the Solar System: 2 dimensions of space and 1 of time.
This "human orrery" is a model of the solar system in which students act out the model and set it in motion. Students measure out orbits for the inner solar system and place footsteps markers along the orbits, to indicate the position of each planet in 2-week intervals. Students take turns in teams of 4 to 'walk the model,' setting the planets in motion, and seeing vividly how the speeds of the planets in their orbits depend on distance from the Sun.
