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
