    Take a hammer, and hammer 2 long nails into the sticks, one at each end. The nails need to be long enough to pierce the wood so that the point stick out about 1 cm (ask an adult for help if you need it).

    Line up the sun, the earth ball, and the moon ball. (You will see how the earth blocks the moon from the sun. This is an eclipse of the moon.)

Tips

  • If you point the moon ball towards the moon, you will see the same phase as the real moon.
  • Paint it if you want.

Warnings

  • Be careful with the hammer!
  • Never look directly to the sun.

  • 1 ball about 1 centimeter (0.4 in) in diameter
  • 1 ball about 4 centimeter (1.6 in) in diameter
    • If you can not find balls, make your own Plasticine, but make it the same size.
  • A hammer
  • 2 long nails
  • A wooden stick 1 centimeter (0.4 in) long
