Observing the Sun and the Moon

Age 7 to 14 Challenge Level:

Here are some questions you might explore, or you may have your own questions about the sun or the moon which you would like to investigate:

  • the time when the sun sets or rises
  • the place on the horizon where you last or first see it
  • the time when the moon sets or rises
  • the place on the horizon where you last or first see it 
  • the phases of the moon
  • the number of sunspots on the sun and how they move (more information) - but it is very important that you do NOT look directly at the sun.  The easiest safe way to observe the sun is to use a pinhole camera.

A paper plate is a good way to show where there are tall trees or buildings on the horizon which you can use for a marker, and where the sun or moon rises or sets. It's also a good way to show sunspots.
