Activity for Helping Students Understand the Planets Orbits

People Planets
Help your students remember significant features and the order of the planets by “acting out” the Solar System. Create groups of nine or more students and assign a planet or celestial body to each group. For homework ask your students to prepare a costume and a small speech to help others identify their planet. Finally, have each group work together to act out the orbit of their planets for the class or another class in the school.
