Solar System Hike

The purpose of this hike is to give the girls a sense of the scale of the solar system.

You will need:

  • any ball with an 8″ diameter (Sun)
  • a white seed bead (Mercury)
  • a peppercorn (Venus)
  • a second peppercorn (Earth)
  • a red seed bead (Mars)
  • bouncy ball 1″ (Jupiter)
  • acorn (Saturn)
  • coffee bean (Uranus)
  • second coffee bean (Neptune)
  • (optional) Facts about each planet to share at each stop
  • (optional) gravel

You might want to tape the seed beads to white cards so they can be seen when you get far away from them.

Place the large ball down at the beginning of your hike.  This ball represents the sun.  Pick a girl to count out the paces.  She will be the “Spacecraft”.  You can switch out after each planet if you’d like.

10 paces. Place the Mercury seed bead down.

Another 9 paces. Place down the Venus peppercorn.

Another 7 paces Earth

Another 14 paces Mars

You may want to scatter some gravel between Mars and Jupiter to represent the asteroid belt.

Another 95 paces to Jupiter

Another 112 paces to Saturn

Another 249 paces to Uranus

Another 281 paces to Neptune

After Neptune you can explain that it could be as much as 242 to the dwarf planet Pluto.  You can discuss the other dwarf planets and asteroids and comets that make up  the Oort cloud.  Feel free to scatter more gravel.  Then head back along the same path to collect your planets
