Description
This lesson combines a series of activities to compare models of the size of Earth to other planets and the distances to other planets. Activities highlight space missions to other planets in our solar system.

Objectives
Students will:
• Use models to compare sizes of planets and measure the distances of the planets from the sun.
• Describe the different space missions to other planets in our solar system.

Lesson Activities and Sequence

  1. Exploring Planet Sizes
    Students investigate planetary sizes by using models to represent planets in our solar system. (Page 30)
  2. Earth, Moon, Mars Balloons Activity
    Construct a scale model of the Earth-Moon-Mars system in terms of planetary size and discover how far one might have to travel to get to the moon or Mars.
  3. Walking the Planet Distances
    Students walk the distances among planets using meter measurements.
  4. Solar System Missions
    Students research recent discoveries about our solar system using NASA Internet sites.
